WOW! My 2001 X5 4,4 sport is presently at the dealership with this same "TRANS.FAILSAFE.PROG" error message. Mine occurred with only the error message and a disengagement of the driveshaft, ie I ended up coasting on the interstate. Fortunately traffic around me disappeared and I eased over to the side from the 3rd lane of 4 northbound lanes on I-15 in Salt Lake City.

In an hour, I plan to call them and suggest they check out what you have found in your situation. Only difference may be that I have a Dinan throttle body. So I'd like to know where the gasket came from?????

Thanks for sharing!
