Get your car to a bmw repair center! I had to replace my automatic transmission, had the same problem. Transmission fluid is a lifetime oil, and should be left alone! These transmissions are made in USA,and they ****!!!

Before you make any other moves, I would try having the transmission flushed and refilled and filters changed and if that doesn't work, you may have burned out the modulator so you may have to shop around for another transmission or have that one rebuilt, whichever would be feasibly financial for you.

sometimes it will clear if you turn the X5 off and restart it. however, it could be an early indication that the tranny is about to expire. i have had it happen and it cleared with a power cycle, but also had friends where it cleared for a few weeks/months and returned. this time it was really the transmission that went bad. if you can't get it to clear, then i'd suggest taking it to the dealer and have them plug into it to have a better look.

this is normal to some extent to try and warm up the tranny to opp temperature as soon as possible. make sure the vehicle had the latest software installed in the transmission as this could also cause a delayed shift when cold.

filter and fluid. If that doesn't do it $4000 should do it.
