What does chips look like in the automatic transmission oil? Aluminum chips in DCPP

03.08.2010, 12:24

Actually it bothers. That when checking the oil level in the automatic transmission, it was said about the presence of chips. At the request, I saw only dark butter, I thought that the chips should look like that in the form of a habit of less large sawdust. What this usually speaks in terms of most likely the wear of what parts of the box, i.e. The color of the chips and oil.

Thank you in advance.

P.S. I used someone with a khoklyatsky additives "Avtovitamin" with nanoalmazami. One comrade promised that after processing, the automatic transmission will earn noticeably better, in terms of shocking and sounds when switching from "D" in "R".

But it is in vain. No need to pour into the box what is not prescribed by the manufacturer

Comrades who have any opinions about additives? The opinion of Ioanna is important, but this is the opinion of one person. Maybe somebody used.
And is it worth climbing to repair the box if switches normally, only warming up a small push when switching from "R" in "D".

IOANNA opinion is important

This is not my opinion. This is the opinion of the manufacturer. Unfortunately there is no representative

How much I remember from numerous posts is our feature ...

Thanks for the answer. What do you think about chips in oil, should it be visible?

04.08.2010, 20:13

Ideally not :)
And if you can see, this is an alarming bell. Also, the oil should not be smelling Gary, should not be dirty (dirty and dark it is different things).

Added a little later ---

And if the question is about how exactly this chips looks like, you can take a piece of soft metal, swing it with a large file until sawders will be sprinkled. This is how the chips look like.
And friction chips look like black little fibers.

Clear. I will watch.

The people still have a question ...
Good day.
The automatic transmission masters said that if not to repair the box, then it can burn. Those. Hydbot seems. The main chip argument in oil. Comp. Diagnosis was not performed. How likely is it?

This feature of the funny boxes and motors, on sound between R and D, everything is clearly without shock: MrGreen:

Thanks for the answer.
Do not be a nasty in the tiptronic, repairing dear!

Of course, peeling dust or small metal sawdust, very tiny.

Before that there was a car with MCP. When changing the oil there was a little sawdust of metallic. However, after the shift traveled four years. There were no problems at all when gear shifted (included with almost one finger), nor when driving. In the course of operation, there must be wear of parts, because it is normal. Does the automatic transmission can "burn" if it is not repaired on time. It seems to me how a maximum, during normal operation, the frictions will erase with time, and it will simply stop touched from the place, or switch the transfer. Is not it so?

and I have such a problem ... I was on the diagnosis of automatic transmission - I do not remember any errors ... When opening the bottom pallet - 800 ml of oil ... The smell of Gary and the oil is dark .. that there were sawdusts (small sand grains) .. . If you have to drive away very much drops 4 transmission ... In a small slide, it does not pull more than 80 (only turns are growing, and no speed), 3 transmission also raises, but only at the moment of switching ... you have to accelerate very smoothly (after 80 km \\ Also, when opening it turned out that it was revealed before it (the bolts and the gasket were not relative). I would like to know your opinion. Thank you!

Even with very neat operation, the automatic box sometimes grieves the owner of the car by various problems. If you feel about the machine, it is not particularly scrupulous, one of the probable incidents can be chips in automatic transmission. Let's talk a few more on this topic.

Most often in the automatic transmission, the correct operation of mechanical, as well as hydraulic parts is disturbed. To reveal the causes of the problem, the node for a hundred is removed and disassembled. Primary diagnostics of automatic transmission during disassembly may show chips in the unit of the unit. An experienced master can understand a lot when seeking such a technical picture.

For the owner of the car, the first communication with the box will be the replacement of oil in the automatic transmission. Pure grease recommended by the plant guarantees very long work automatic box. Well, and do not forget about the maximum level. The state of the working fluid correctly displays many damage arising in depths automatic transmission car.

First diagnostics

How to reveal the condition of oil in automatic transmission? We take a piece of pure fabric, and be sure to light. We rinse this matter with oil. This procedure will well show you the presence of extraneous garbage in lubrication. If a lot of metal chips, the state of the node can be safely considered an emergency. A lot of chips in the oil speaks of reinforced wear of iron. Fragments and fibers of the metal clog filters, solenoids, as well as hydroblock channels.

If the chips in the automatic transmission oil is present in small quantities, you can not worry about the serviceability of the system.

Even to identify the status of the automatic transmission, the pallet should be examined. If there is a garbage in the box, then it will definitely accumulate exactly there. Specifically, the Magnets of the Machine Pallet should be inscribed.

Having found sharp metal fragments on them, you can judge two faults:

1. Planetary gear was worn out
2. The thrust bearing crashed.

In addition, the Satellites of the automatic transmission can be supplied. In all these cases, the node will have to be removed from the machine for subsequent parsing and repair.

Aluminum chips, and then the pieces on the pallet automatic transmission can talk about a whole range of breakdowns:

1. The aluminum sleeve was worn out (it is located among the elements of the planetary transmission).
2. Extermining the sliding bearing or the same thing happened with a stubborn bearing of differential.

In the service center to eliminate the fault, the automatic box is disassembled. Bearings, sleeves - all this changes to new details. This occurs, in particular, the replacement of the differential with the bearing, and the worn socket is restored or also changes in case of extreme wear.

Sometimes there is plastic on the bottom of the pallet or pieces, particles of textolite. It is recommended to check the pump puck, coupling and plastic bushings. Repair involves replacing faulty parts.

And small rollers may be present on magnets. This signals the destruction of the roller bearing. The wizard after parsing the box will find the bearing, will explore the rest of the details and will repair. Well, if you find friction chips on the pallet - therefore, it became defective a box of the box.

One of the main problems of automatic transmission is the abnormal work of the mechanical and hydraulic part of the unit. To determine the cause, disassembly and disassembly of the transmission are required. With the primary diagnosis of the disassembled unit, the presence of chips in oil and the pallet can tell a lot to the experimental master.

Chips in oil

The first communication with its transmissary for the car owner begins with replacement oil ATF.. Pure, in sufficient quantity working fluid - The key to the long life of the automatic box. Most of the problems associated with automatic transmission are very accurately displayed in the state of its working fluid.

To determine what state is transmission fluid, take a piece of light matter and wet it with oil. Such a procedure clearly shows whether there is an extraneous garbage as part of oil. The presence of a large amount of metal chips is an emergency indicator of this expensive node. This means that iron, fibers and particles whose particles are clogged intensively in the automatic transmission. oil filter, Hydrock channels, solenoids.

A small amount of metal chips in oil is not dangerous.

Chips in the pallet

Another way to check the condition of oil and transmission is a pallet inspection, since some garbage is usually accumulated on the pallet.

If sharp and large iron fragments are adjusted on the pallet magnets, this testifies to the wear of the planetary gear or that the stubborn bearing crashed. Other possible reason The appearance of iron chips is the wear of the gearbox satellites. In such cases, the analysis of the machine and the replacement of the details failed.

If at the bottom of the pallet is visible aluminum chips or pieces of aluminum, then one of the reasons for their appearance can be: abrasion of the sliding bearing; developed its resource aluminum bushing, located among the details of the planetary transmission; Wireless discontinuity bearing. In service centers, to eliminate these faults, disassemble the automatic box and replace the wear bearing, or find items with an emergency sleeve and change it, or change to a new differential with the bearing, the nest is restored, and the nest change with strong wear.

When plastic chips, textolite or plastic particles are found at the bottom of the pallet, pay attention to the condition of the plastic bush. Another reason - the puck of the pump or coupling crashed or crashed. During the repair process, change the damaged item.

When the small roller pallet is detected on magnets, check planetary mechanismsince most likely it crumble roller bearing. The masters disassemble the transmission, find the location of the bearing, study the integrity of the remaining parts, and, if everything is in order, the bearing change.

The particles of friction chips on the pallet indicate faults in the hydrotransformer.

Signs:

The car is either not moving at all or constantly sinks (there is no overclocking on the engine rolling speed), fault box machine either a complete lack of switching, noise from the machine, etc.

How to check the oil in the automatic transmission In most cases, it is under the hood, but in modern cars still practiced to "hide" it in order to eliminate cases breakdowns automatic transmission associated with the human factor. So it is not at all necessary to look for it and blame the manufacturer and / or the past owner in this, everything is much easier - the installation of stationary probe on certain types of automatic transmission is not provided. If it is not - you need to use the universal service probe. But! On some cars, even universal service probe is not provided, and can be carried out strictly in specialized service centers. In order to certainly know the peculiarity of your automatic transmission, we recommend on our website.

Malthotransformer malfunction: disruption of the piston sealance and failure of the main blocking friction. The destruction of the turbine, overtaking coupling, blades, breaking the drive slots and so on.
