2004 525 had problem last month. Car stuck in N, pressed on gas, engine revved but no movement. Turn car off, locked/unlocked, restarted, worked fine for a mile or two. Then, Warning "Transmission Failure", do not drive above 35 mph. Got home, and had it towed to dealer. They replaced entire transmission, saying it was a controller issue, and that controller was located within transmission. It was better to replace entire transmission than just the controller. Got car back, no problems since. Does this sound right?

 

I'm assuming you have an automatic. If you do, your story is consistent with others that I have heard about. The controller is within the transmission housing and it cannot be serviced by your dealer. The repair is to repalce the entire transmission and have it repaired by AG.

I have heard of this happening to a couple of local cars including a new 7er. It broke down a block away as the fellow was leaving the dealership after picking up his new 745. A group of techs were told to walk over to the car and to push the car back in N past the MB dealer next door.

Made for quite a story at the MB dealership.

 

His sig says he has a stick manual. This problem is more consistent with pennetta's experience with SMG which is also manual.

 

Sorry DrStix67, no car signature and we cannot help. We don't like to guess here.

 

I had the same problem with a Chrysler Caravan years ago. The dealer fixed it and it worked like new. Hopefully, yours will result in the same way . . . working like new.
