Can't tell for certain, but it sounds like the splines on your front driveshaft are stripped. If true, you need to replace the front driveshaft. It's also possible you have a pblm with your rear driveshaft.

Possible Transmission / Front Driveshaft Failure *edit* Rear Axle popped out - Xoutpost.com

Hi, Car 2005 e53 4.8is I have been searching all morning and lots of great info the driveshaft failure, repair strategies etc, however as of right now

xoutpost.com

search E53 front driveshaft

 

This sounds like low tranny fluid. Even though it looks full when you open the "add" bolt; you have to let the car run with your foot on the brake and cycle back and forth thru the gears (P-R-N-D-N-R-P) 3 or four times (holding each position for 3-4 seconds). This will spin up the torque converter, and allow you to put a lot more fluid in. Repeat this process until fluid comes back out of fill hole after recycling gears (only then is it full).

Good luck,

Rickster

 

do you solve the problem please ???i have the same issue

 

Either CV axle popped out of the differential or the splines are stripped at the transfer case.

Need more details on the symptoms to know which or what diagnostic steps to take

I have a 2012 bmw 750li it won't go into gear. It just beeps and returns to park? Any ideas?

 

I have a 2004 bmw 530i runs great but won't move in reverse or drive nothing. 🤔 could you please help me here

 

mannn...I'm going thru the same thing with a 2004 330ci. I just swapped the transmission with lower mileage one. Still nothing...wheels won't move. Torque converter is spinning. Fluids good. I'm gonna see if my drive shaft is spinning while it's in drive today.. gotta a lower a heat shield and look while its up on jackstands. It shifts gears and the idle changes like it's supposed to but nothing to the wheels. I'm beginning to think it's the rear differential completely. If so, I'm swapping a limited slip differential into it. I'll keep you posted. I'm flying blind and I'd like to help people if I can
