What are the common BMW 325xi transmission problems?

Shifting gears

This is one of the most common transmission problems that BMW users experience. This problem is common among negligent drivers. It occurs because the fluid is contaminated or low. That’s why it is important to service your BMW 325xi as recommended by BMW.

To fix this issue, the driver will have to change the contaminated fluid with a new fluid. On the contrary, if the fluid level is low, the driver will be required to fill the fluid to the desired level.

Car shaking on the road

Another common BMW 325xi transmission problem is the car shaking on the road while driving or accelerating. Your car will shake if the transmission is damaged or it has low transmission fluid levels. Your BMW needs proper lubrication that is provided by enough fluids. Hence, if the fluids are insufficient, the moving parts will struggle to operate optimally.

The best solution is to fill your car with the right and enough transmission fluids to avoid it from shaking. And if the transmission is damaged, have it inspected and fixed by a reliable mechanic.

Car grinding during acceleration

If your BMW planetary gear system is compromised, you will start to hear a grinding noise. The car’s planetary gear system ensures that the speed of your vehicle’s wheels matches the speed of the engine. So, if the engine and wheels are not in sync, they will collide and cause a grinding noise.

To avoid hearing the grinding or damaging your car’s transmission system, you will have to fix the problem by repairing or replacing the planetary gear system.

Burning smell

This is another common problem that different BMW users have complained about. So, if a burning smell is present or the scent of transmission fluid inside the car’s cabin, this is an indication that your transmission is overheating. And the main causes are a transmission fluid leak or low fuel level.

If that’s the case, you will have to find out why your car’s transmission is leaking. Some of the causes are a bad torque converter, failing gasket, bad seals, or damaged fluid lines. Repair or replace the damaged part to fix the problem.

Whistling noises

If you hear a whistling noise when accelerating, this is a sign that your transmission has issues. The first culprit to check out is the alternator belt. The alternator belt is one of the belts that wear out faster in a BMW. Other reasons for the whistling noise may be the clutch pack slipping, thrust bearing failing, or low transmission fluid level.

Before guessing what’s the issue, it’s best to take your BMW to a professional mechanic or BMW service center and have the problem identified. You should replace the bad or damaged parts to avoid hearing the whistling noise again.
