Frequent problems of automatic transmission BMW X5

The BMW X5 is a reliable car and lasts a long time if used properly. However, repairs will be required sooner or later. Various parts break down - including the automatic transmission. Breakdowns can occur due to wear and tear of parts of the machine, as well as as a result of inaccurate operation - due to sudden starts, acceleration, slippage. It is advisable, of course, not to bring this unit to repair and try to extend the life of the automatic transmission. If repair work cannot be avoided, you must go to a service center where qualified people work.

The most common automatic transmission problems on the BMW X5

Typically, the causes of problems are the driving style of the car owner. People drive in low gears, over-accelerate, drive too aggressively. As a result, the components of the assembly wear out at a faster rate. There is gradually less oil in the box, other problems appear. These include:

• strange noise arising from the friction of machine parts;
• untimely gear shifting;
• inability to move.

As for natural wear and tear, it occurs at the moment when the car has already traveled about 200 thousand kilometers. Parts of the oil pump wear out, the input shaft breaks, problems arise with overrunning clutches. There may be defects in the torque converter, which it is desirable to immediately eliminate. Not only the main parts break, the condition of the seals and seals gradually deteriorates.

How is diagnostics performed before repair work

Carry out repairs Automatic transmission BMW X5 must be a specialist. The person must have experience in rebuilding a transmission, as well as access to specialized equipment. During repair work, they perform various actions - they change clutch discs, oil seals, and other elements. The list of operations is not limited to this - the cooling system line is thoroughly washed.

Before repair work, diagnostics are carried out. It includes various procedures. This is a test drive that is performed in order to clarify exactly what problems there are. After a test run, the specialist proceeds to the next step - conducts a visual inspection in order to troubleshoot. This approach makes it possible to understand how worn parts are.

Then computer diagnostics are performed - this procedure is of particular importance in the process of finding problems. For its implementation, devices are used that can determine the type of problem with maximum accuracy. Hydraulic diagnostics are also performed, which is needed to check if the lubricant is leaking.

If during the diagnostics it is possible to identify defects, the box is dismantled and troubleshooting is performed.

What are the features of automatic transmission repair on the BMW X5

If the driver often pressed the gas from a place “to the floor”, it becomes necessary to repair the oil pump bushings. When it is necessary to change the lubricating fluid, you should clean the adjacent units, and also replace the filters. This is important - otherwise, a blockage may occur in the cooling system, after which the oil pump may break.

This gearbox is often repaired due to worn solenoids. If the owner is negligent, oil starvation may occur. It causes the valves to stick. Due to the problem, the solenoids burn out. The consequences are different - the pressure decreases, the temperature sensors fail, the automatic transmission goes into an emergency state.

It is important to prevent the occurrence of all these problems. Regular preventive maintenance is required – at least once a year.

How to extend the life of an automatic transmission

It is important to take good care of your car. To increase the period of trouble-free operation of the unit, you must follow a number of tips - change filters and oil in time. Gradually, the former become clogged with foreign particles, as a result, the rate of pressure growth becomes less, and the amount of oil decreases. Over time, the speed at which gears change decreases. Extraneous noise indicates a small amount of oil, as well as a long gear shift. Lubricant must be changed every thirty thousand kilometers. Replacement after the winter season is also recommended.
