View Full Version : 07 525i transmission question
05-10-2010, 09:29 PM
Purchased a CPO in November of 09, recently in traffic going and coming from work have noticed that at around 15-20mph and 1500-2000rpm that while just lightly/barely accelerating when it upshifts I have been feeling what some call "shift shock". Wanted to know if anyone else has experienced this and if it is normal.

Normal if you had been driving less aggressively... try standing on the pedal once in a while to give your tranny a better adaptation. Some festers here will tell you to reset your tranny... you can do that as well, which forces your adaptation to shift to a more aggressive mode.

Yeah less aggressive would describe the way I have to drive because of NYC traffic. Every once and while when traffic lets up I try to open open bust mostly I just get stuck in the stop and go stuff. Thank for you help this is my firs BMW and was worried the transmission was damaged or something worse. Guess like you said the "shift shock" and slight lag comes from the stop and go traffic.
