Honda CR-V: What you need to know before buying. DIY repair of Honda CR-V automatic transmission repair Honda CR-V

The automatic transmission switch is the most expensive repair of the vehicle, which is why when the first signs of problems appear, it is necessary to immediately eliminate the defect. If this is not done on time, then in the future it can turn into more serious problems. And if you contact specialized service, then repairing there can do it very expensive. Motorists, having studied the market of spare parts come to one conclusion, the repair of their own hands is a pretty good idea, as it can be significantly saved.

We prepared this article for those who have never come across problems in the gearbox, and also if you have conceived to repair it on your own. We will tell you in detail on the example of how the repair of the automatic transmission of the SRV RD1 is done with their own hands. We will also share with you interesting knowledge, in the future they will help you extend the life of your car.

Do I need to do repairs yourself

In the 21st century, absolutely all cars moving in roads are insured, in case of malfunction most of Costs will be able to be covered. But the insurance also contains the conditions that repair and maintenance can be made only in special auto repair shops. Otherwise, if suddenly the repair was carried out in other places or independently, then all warranties will be lost.

And if you still decided to make repairs with your own hands, then you must realize that in the case of disassembly of any parts of the car, no one will pay damage to it.

How to exploit the gearbox

It is strictly forbidden to move the car with towing, especially if there is an excess in the oil box. We should not forget to make the replacement of oil in the car - it is recommended to perform every 20 thousand kilometers. This, of course, is an individual indicator and depends on many other factors, but it is necessary to accurately change more often than 1 time per year. Too many oil in the box - it is also not good because it will begin to foam and will be badly removed from the transmission. Therefore, it is desirable to check the oil always when you especially are going to the long journey.

How to diagnose and repair ACPP Honda do it yourself

The whole process occurs according to the following plan:

Full diagnostics.

Removing the box from the housing.

Disassembly box.

New grade spare parts.

Reverse assembly.

Installation.

Repeatal.

The structure of all ACPs is equally, and therefore it will insuffize difficulties. Differences are available only in a transmission control device, it can be either electron or hydraulic. And therefore the repair process will have minor differences.

Causes of malfunctions of automatic transmission

Most of all problems with gearbox occur due to improper operation of the car. Now we share the main factors that will continue to violate the work of the entire transmission:

Insufficient or redundant oil level, the gears and breakdowns can be increed rapidly and breaks when switching;

Towing, we have already talked about it, and you need to remember that you should not tow a car;

Sharp braking and acceleration also lead to rapid wear of parts;

The gear shift knob is jammed - learn more about how the automatic transmission is being renovated http://atfservice.ru/.

First signs of trouble

Violations in the work of the gearbox is desirable to find at the very first stages, so it does not have to completely sort out the box and strongly disappear. Signs of problems in the box abound, but we will tell the most frequent:

Characteristic sounds when switching transmissions, a foreign smell may also be present;

If the transmission does not turn on at all, this is a sign of a serious problem, and it will be necessary to do an emergency repair;

You should always check the surface under the car, there should be no stains. If they are detected, then this is talking about leakage, and this problem will need to be solved.

Repair of automatic control Honda SRV RD-1 do it yourself

Repairs this car You can do both from specialists and do it yourself. Like all cars in order to disassemble the box it needs to be removed. To do this, you need to disconnect the subframe, to disassemble the lower stabilizers. The repair process is concluded in the disassembly of the box, identify problems and eliminate them, and then all this work is done in reverse order. No need to forget to check the operation of the hydrotransformer, and all the integrity of its device. Because there may be worn items, and this is not good.

Next, it is necessary to check the condition of the friction departments, they may fail very often, mainly due to sharp braking. After all the points done, it is necessary to back the box in the car. First of all, all attachments, and then a hydrotransformer, and at the end to fix disposal box. It should be noted that such a job requires at least minimal knowledge in the structure of the car. You can repair the car "Honda" CR-V with your own hands, but still there are such cases that you will have to refer to professionals to the maintenance station.

Precautions during car operation

The box is a very complex mechanism for which it is necessary to care for, otherwise it can lead to negative consequences. If you take care of the car correctly, then the repair of the box may not need even after 250 thousand kilometers. So try to drive correctly and not rape your car. In an example of good maintenance can be brought japanese cars 80s release. Some of them have already drove about a million thousand kilometers. Do not forget about your car, and then he will last long years without overhaul.

We hope that our article was useful for you, and you were able to figure out how to repair the right automatic box Gear "Honda" SRV RD-1 with their own hands. You should not wait for the scary signal from your car so as not to change it. Pay attention even in small signs, and then the car will thank you for a long service life. We wish you success!

Depending on the year of the production and volume of the engine on the Honda CR-V car are installed the following models Boxes: M4TA, MDMA, S4XA, SKWA. However, regardless of the existing model, with automatic transmission vehicle Problems may occur. And if you run this case, the repair of the M4TA boxes, MDMA, S4XA, SKWA can do it very expensive.

Repair of automatic control Honda CRV - Prices

To identify the problem as early as possible, pay close attention to the operation of the ACAP SRV.

Major malfunctions Honda CRV:

• Shoes when switching gear. This indicator is, if shocks occur in the automatic transmission Honda CR-V When switching gear during a quiet ride. The reason for the reason can lie in oil starvation of the hydraulic system.

• Pinky when pressing the gas pedal. The reason lies in faulty work Hydraulic system and pump. Here, the repair of automatic transmission of Honda SRV often reduces to restore normal operation of the hydraulic system or to its replacement.

• Shone, slip, Peregazovka. This malfunction in the operation of the Honda CR-V automatic transmission in most cases is caused by oil leakage and full clogging fuel filter Automatic transmission

However, even if you probably know the reason for the malfunction and the possible ways to solve it, we strongly do not recommend repairing the automatic transmission of Honda SRV. It is better to entrust the repair of the box of the Honda CRV machine to specialists - in our autotech center using modern equipment, we will thoroughly reveal the cause of the problem and will help to eliminate it as soon as possible.

Replacing Oil in Honda CSP

As it was already noted earlier, a number of causes of Honda SRV automatic malfunctions can be caused by a leakage or clogging of oil into Honda CPPs. To avoid a similar one, it is necessary to check the oil level in the automatic transmission in a timely manner, its consistency of the IPRY need to replace oil in the box.

To facilitate your task, our car service offers its oil replacement services. We have the most affordable oil replacement prices in the CR-V box. Our employees will help you choose aTF oil For Honda CR-V, and also provide all required spare parts CR-V automatic transmission if necessary repair automatic transmission chonda CRV in Moscow. High quality and acceptable cost of repair ACP HONDA CR-V and oil replacement are a guarantee of our work.

Honda CR-V fourth generation - Compact japanese SUV., very popular on russian market. The machine is well in demand with an automatic transmission, which provides comfort in the city and convenience of control. But that the transmission always pleased its owner, it must be serviced in a timely manner. Fortunately, some procedures with this automatic transmission can be performed independently. For example, change the oil in the box. This procedure does not require professional skills. To do this, there will be enough set of hand tools, as well as special materials. Consider in detail how to replace the oil into the Honda CR-V 4 automatic transmission.

The transmission fluid in the automatic transmission changes depending on the mileage. The manufacturer claims that under favorable conditions, the replacement regulations are 40-50 thousand kilometers. But in the harsh operating conditions, the replacement frequency is strongly recommended to cut up to 30 thousand km. In extreme cases, changing the factory oil for the first time after 15 thousand kilometers, and when buying a supported machine, the oil must be changed immediately - so safer, safer, and more confidence that the box will serve as longer as possible.

Should I wash the box?

Definitely stands. Over time, the oil loses its lubricating properties, and the internal components of the checkpoint can be cooled, which result from overheating and are rapidly wear out. At the same time, mud sediments and metal chips accumulate inside the box - a consequence of mechanical wear of parts.

We note that some Honda CR-V configurations are not equipped with a removable pallet, so many dirt accumulates in the gearbox. All this torture also scores the oil filter, which also has to change.

If the specified problems are not paying attention to the specified problems, sooner or later the gearbox will be unusable. Even in the dealer center, they may refuse to take place for repairing the checkpoint, and advise to replace the box to a new one. Therefore, it is necessary to check and change the oil regularly, at least every 20 thousand km.

Partial replacement of oil

This procedure is considered the most common, since it does not take much time, and it is enough for the transmission to light throughout the operation of the car.

What to pour?

Most proper oil For automatic transmission HONDA CR-V 4th generation liquid ATF. DW1. Alternatively, you can recommend ATF Z1.

Materials for replacement

• Tools, keys and heads
• Ribs, gloves
• New oil
• New oil filter
• Capacity for the drain of old oil

Sequence of work

1. The engine is heated, the car is placed on the overpass. Alternatively, the overpass or observation pit is suitable
2. Give the engine to work for minutes, drown, then open the hood and measure the level of the remaining oil in the automatic transmission
3. In the appropriate place under the bottom of the car you need to remove the Carter to access oil filterwhich must be replaced. Also in this place there is a plug plug, it must be unscrewed and drained the waste fluid - in the pre-prepared pallet. This should be done carefully, since hot oil can cause burns. Note that the drain plug (for the oil drain) is unscrewed using a 3.8-finger
4. Wait until the oil is fully extended from the automatic transmission. About 3.5 liters of old oil should pour out
5. On the drain plug can remain metal chips and dirt, it should be cleaned with special composition WD-40. In addition, there is an aluminum washer in traffic, it should also be replaced with a new
6. Install the plug in place and start the bay of the new transmission Oil. To do this, you will need a hose or funnel. Alternatively, a special syringe is suitable. It should be connected to the hose, which, in turn, should be inserted into the plug-in neck, having previously measured the measuring probe. Pay attention new liquid It is necessary to pour as much as the old oil flowed.
7. It is better to nourish oil a little than to pour. You can add later, after starting the engine. Then the control measurement is done, and the liquid is agreed as needed. Some masters believe the oil must be at the level between Max and Min tags on the diploma - it is considered the most optimal level.
8. A week later, you can measure the fluid level again.

Transmission with planetary gears is generally distinguished by excellent mass boar characteristics, not in vain on the legendary Ford T stood just such, only with manual, or rather, the "foot" control. The first attempts to adapt the torque converter to move the machine showed that the ideal combination for it will be the planetary transmission, which is very easily translated into automatic control.

In the future, designers focused on improving mostly this option, and only now alternative schemes began to apply quite widely. And before the second half of the 90s there were practically no options. Yes, the variators were produced more or less massively, but even the speech was compared with "decent automatic transactions" - it was a transmission of purely for light cheap machines or motorcycles.

But other automatic transmissions were promptly produced - in particular, the combined automatic transmission company Honda, and then Mercedes. This branch of development is radically different in the design of its "relatives", has both advantages and disadvantages.

What are bad classic "planetary"?

With all the advantages of planetary gearboxes, they have at least two drawbacks in the automatic transmission. Firstly, this is the association of transfer numbers of all transfers, because the planetary programs are collected in the "rows", and cannot be changed the gear ratio of only one transmission, without affecting the rest. This complicates the selection of transmission gear numbers, have to make compromises that, with an increase in the number of gears, are becoming less significant.

Secondly, all the components of the "chain" of the gear ratios are experiencing different loads of the engine torque: one above, others are significantly lower. And the duration of this load is also different. And when the most loaded row fails, it usually loses the performance of the entire transmission.

Thirdly, in the technological plane, planetary automatic transmission is very different from the MCP passenger carswhich have been released only for a long time. Therefore, the manufacture of automatic transmission requires completely other production lines, calculation systems and technologies. And this is money.

It is necessary to admit that against the background of such advantages as compactness, almost complete unloading of the automatic automatic automotive case and the convenience of hydraulic control. These shortcomings are not particularly important for most automatic transmission manufacturers. However, there was a company that tried to refraart the trend.

Birth Hondomatic

Honda is generally distinguished by some originality of structures. It is now they are quite a conformist, and in the 70-80th originality bash. So when creating automatic transmission, they distinguished themselves, using a far-nontrivial scheme. First Hondamatic for Maltro models Honda. N 360 AT was presented at the London Motor Show October 18, 1967 and produced a furor, since it was the first use of motor automatic transmissions so small volume.

The box was made without the use of the technologies of the main patent holders in this area, in particular BorgWarner, the cooperation with which was not charged at that time. Already the first three-stage automatic transmission were valves, a similar scheme was chosen for efficiency and high efficiency.

Unlike American machines, this box should have been applied with low-power motors. Then tested on the machines, the Honda design was installed on motorcycles. In 1976, the automatic transmission appeared on the Honda CB 750A Hondamatic, and then it was equipped with motorcycles with motors of 400 "cubes".

By the way, another unique feature of the classical automatic transmission from Honda became the design of the control system. Let me remind you that the box you need to "know", which torque gives out the motor to switch "upstairs" or "down". At that time, data from the motor did not seem to be possible from the motor possible, for in the go were mostly carburetors without any electronics. The "classic" method was in the pressure measurement in the intake manifold before and after throttle valve, as well as monitoring the position of the gas pedal. Indirectly, it gave some idea of \u200b\u200bthe current torque.

But the system estimated it inaccurately, and therefore needed setting up for each particular engine and was sensitive to the failures of the control system. I needed an alternative approach, and the engineer Torao Hattori found him: he used the simplest physical principle.

The moment at the GDT stator is always proportional to the moment transformation ratio. This means that if you connect a control system to it, it will be able to automatically change the transmissions, depending on the load and the transformation coefficient in GDT. It turns out a practically ideal system that can determine a large and low load on the motor, regardless of its real power.

A similar design in combination with the comb reducer had a sufficiently large efficiency in order to be successfully applied on the smallest engines and, moreover, it worked well at high speed of the shafts (which was important, given the "horse" character of Honda's motors). Moreover, Honda appeared to the BorgWarner designers to develop a layout, but harsh professionals answered that the creation of automatic transmission for such speeds and low-power engines is impossible.

Truly, the wedroom and control system with controlled hydraulic pressure valve turned out to be continuously created for each other. In the compaction automatic transmission, unlike the planetary, not necessarily unblocking the clutch-frictions to enable increased transmission. It is enough to put the overtaking coupling between the first and second transmissions, and switching 1-2 will pass only by incorporating the adhesion of the second transmission.

Let me remind you that the overtaking coupling is a passive element of the automatic transmission, which allows one of the shafts to rotate relative to another only in one direction. When the first transmission turns on in the batter, the speed of rotation of its drive gear of the secondary shaft is lower than the rotational speed of the driven gear of the secondary shaft of the second transmission. Just due to the difference in gear ratios.

If the overtaking clutch was not, when the "fast" second transmission is turned on, it would be necessary to disconnect the frictions first. But the coupling of free movement this question solves, and significantly simplifies the management. The automatic transmission of such a design costs a fairly simple control system. The first transmission springs in it are always included in the DRIVE position, and as the second and other increases are turned on as overclocking.

The use of such an "alternative" scheme allowed us to successfully apply automatic boxes with small "twisted" motors, and the switching speed of 1-2 best affected the time of overclocking to hundreds, which was playing on the hand of the company's sports image.

The first boxes were two-speed, then the third was added, and in 1982 there was a four-stage automatic transmission of the same scheme for the Prelude model, but already with a more traditional pneumohydraulic control system.

Great freedom regarding the gear ratios mentioned above, generally made Hondovsky combat quotes much more efficiently than planetary competitors.

And in addition to a good working range, reliability was a big advantage of such structures, and the matter is not only in the manufacturer. As I said, in the compact automatic transmission all the programs do not depend on each other. Does not turn on the second? Nothing, rides on the third. Does not turn on the third? We are going on the fourth and fifth.

In addition, the case of the box is loaded with the moment, and therefore the shafts rotate in roller bearingsWhat means the minimum number of elements with sliding bearings sensitive to lubricant. Here everything is monumental: the balls and rollers work with minimal oil pressure, are not very demanding to temperature modes. The mechanical base of the box is much less vulnerable to both oil contamination and its temperature.

And of course, the friction sprouts themselves are tritely more reliable, because even with maximum relief, they have a very gentle mode of operation. Any frictions are loaded only at the time when the transfer is on, all the rest they do not work and cooled, wear products from them are washed out. And the clips of higher gears and the first are made with a good safety margin, besides, access to the first transmission is possible outside - it is not necessary to even remove the box. As a result, the springs resource for 300 thousand kilometers, and after this mileage you can simply be replaced, not the touch of the rest of the mechanics.

Improvers

It was to the wind automatic transmission that Mercedes turned, developing "automatic" for its first front-wheel drive car. The company whose products then produced underlined reliable and comfortable, preferred the wedlique scheme to create its automatic transmission type 722.7. From 1998 to 2005, these boxes were put on cars of A-Class and VaNeo with motors up to 2.1 liters. Like Hondovsky structures, he also turned out to be extremely reliable.

Disadvantages and limit of construction

Honda CR -V Third Generation, Last Year Restyling, is still sold with a 5-speed box. Why? Because more gear from the battery to be, alas, can not.

1 / 2

2 / 2

An increase in the number of transmissions on the compact automatic transmission was at first easy. To go from three to four and four to five, it was not necessary to break the established structures (as on planets), it was enough to add another pair of gears and grip for them.

It was the five-speed automatic transmission that appeared in 2001 became the design limit. In the future, restrictions began to affect the dimensions and mass, which from the very beginning there were more in such designs than that of planetary boxes, and only due to successful constructive solutions at some stage, this flaw could be smoothed.

If you leave the patent cleanliness and dependence of the BorgWarner Heritage dependence, then obvious disadvantages of the basic boxes are dimensions and weight. The trivial automatic transmission for four or five steps is noticeably superior to the Gabarities of the MCPP with the same number of steps and even a five-six-speed "planetary".

Traditional boxes with an increase in the number of gears almost do not increase the dimensions, because it is possible to facilitate the design due to the frontal gear ratios, and each in the boom box each new gear leads to an increase in dimensions and mass.

In addition, Honda did not sell their automatic transmission "to the side" and did not transfer the patents to anyone. Yes, and they were not designed for powerful and low-speed motors from the United States, which in the 80-90s there was a lion's share of sales automatic transmission in the world, and in Japan, competition was great and without them. Toyota used Honda's work. The time of their technological leadership remained in the 90s.

Instead of good farewell

However, the story has not ended. If you look closely, modern preselative "robots" is pretty reminder of the same Hondovskiy boxes, only instead of the friction package for each transmission of the frictional frictions, and they are called clutch. And the shafts and gears of each gear ratio are included in a classic way, couplings.

Which is the reliability of such structures, which is now clearly not comparable to the Hondovskaya "classic", then give her time, at least ten years for improvement. They will show us again.
