Common Problems in the Gear Assembly of BMWs

BMW Gear Set

When it comes to superior car models based on performance, safety, and comfort, the BMW takes one of the top slots. The vehicle has been designed to give its drivers the perfect experience on the road, with cutting edge technology being incorporated into it over the years to ensure it remains to be among the top choices for many buyers.

Unfortunately, the BMW is still not the perfect car, as there are still areas that have brought forth a lot of complains from their customers. A common complaint that most BMW owners tend to have is related to the gear assembly.

The gear assembly is a system that enables transmission of power within the different parts of the car. It consists of rotating cog wheels that transmit power in their rotation from the internal combustion engine to the wheels of the car. This therefore means that it is the gears that control the speed of the car. The gear assembly also increases the torque while reducing the engine speed in order to slow down the car.

Problems Associated With the Gear Assembly

Some of the common problems that have been linked to the gear assembly in BMWs include difficulty in shifting between gears, irregular shifting from gear to gear that may be the result of the gears bumping into one another, increased wait time when shifting from gear to gear causing the engine to rev, and complete failure of the engine to shift or respond as required.

In addition, you may feel the gears slipping or experience some pulsations in the gear as you attempt to engage them. A burning rubber smell may also emanate from the clutch. All these issues are signs pointing to gear assembly problems.

Causes of Gear Assembly Problems in BMWs

Problems related to the gear assembly can pose a major safety issue to the driver as well as anyone driving near them. This is because when the gears are miscommunicating, the wheels also get caught up in the trouble and they may not respond as required, and this can cause accidents on the roads.
Some of the causes of gear assembly issues include:

Leaking transmission fluid

When the seals in the transmission fluid gasket become loose, the transmission fluid will leak out. This will cause the gear assembly to lack lubrication and the ensuing friction will cause difficulty in cog movements. This difficulty then causes the stutters while changing gears. When the transmission fluid is low, the gears will also start slipping and there will be a lag time when switching between gears. You will get a notification that the level of transmission fluid is low when you try to accelerate. This is because more transmission fluid is put to use when you engage higher gears.

Cross-contamination of transmission fluid

This happens when the coolant in the radiator finds its way into the transmission fluid chamber and mixes with the transmission fluid. This contamination will impair the performance of the gear assembly and in turn necessitate a change of the fluid.

Damaged solenoids

The solenoids perform the task of regulating the movement of transmission fluid within the gear assembly. When they become damaged, the level of transmission fluid in the gear assembly may go down, causing issues in the transmission. The solenoids may also fail to function within the valves as a result of reduced fluid pressure.

In addition, overfilling the transmission fluid may also impair the gears from shifting smoothly. Too little transmission fluid may cause problems in your BMW’s gear assembly, but so will filling the fluid way above the recommended level.
