Car automatic transmission filter

Hydraulic filter is necessary for every hydraulic system. In the car hydraulics may be used for servo-assisted steering gear or for brake gear. In the hydraulic system liquid is used. As a rule, it is special oil for hydraulic systems. This mineral oil passes through reservoir. In order to prevent system’s dirtying, there is a filter directly after the reservoir where all the undesirable parts are collected.

If the storage conditions were not followed, there are may be admixture in the oil. Also when oil filling, suspended materials may get into the hydraulic system. There is no necessity to find out how foreign bodies got into the oil for hydraulic filter. For service life period and optimum hydraulics work it is very important to remove them as quickly as possible. In course of time hydraulic filter may block. Then it is necessary to change it. Car makers recommend how often it is necessary to change the filter. Car owner must follow these terms.

It is not difficult to change the hydraulic filter. There is no necessity to do this by yourself because it is done during the technical check up. In case when the hydraulic system doesn’t work correctly you need to check the hydraulic filter. If it is very dirty, this may be the cause of the faulty operation. If you want to order starter, heating radiator, saloon air filter, poly-V belt, conditioner branch, receiver-drier, brake calliper or another part for your car in our online store you can find qualitative car parts at moderate prices.

How to detect the automatic transmission filter failure

To perform an independent diagnostics of the automatic transmission filter, you have to visually inspect it. A properly functioning component is not warped, has no visible damage, the filter element is polluted not more than by one third. If you have not detected any failure symptoms, but the filter does not operate or functions incorrectly, have it diagnosed at a service station where, using special equipment, specialists will determine if the pressure during the bypass valve opening corresponds to the norm.

You can identify that the automatic transmission filter requires to be inspected by the following symptoms:

• corrosion, damage, visible stains of working fluid on the component;
• transmission sometimes malfunctions;
• the working fluid has darkened, sediment was formed in it;
• an abnormal noise comes from the gearbox.

Causes of the automatic transmission filter failure

It is important to understand that poor quality parts have a much shorter service life. If too much force is applied to the component in the course of installation or during its use, the part will fail prematurely as well.

Delayed working fluid replacement or its low quality, impact of moisture and other aggressive factors can result in premature filter element wear and the part corrosion. If the operating pressure in the system is exceeded, the valves may warp.

Replacement of the automatic transmission filter

Scheduled replacement of the part is advised to be performed every 20,000 km. If the component has failed prematurely, you have to replace it immediately. Use of the car with a faulty filter is not allowed, therefore, it is advisable to have a spare automatic transmission hydraulic filter kit.

All replacement works must be performed exclusively at a service station, as they require specialized expertise, and installation mistakes will result in the transmission malfunction. The working fluid and the gearbox gasket are replaced together with a new filter installation.
