Tranny searching when cold
Hey guys, I have an 03 745i with 129k.. it shifts fine and I tried doing the pedal thing for 30sec, not sure if it helped, I think it did, but could be in my head.. anyway I just got the car and the PO said the tranny pan and fluid was done 6mo ago.. anyway, I just noticed a week after I bought the car that after I start it up for the first time cold in the morning and take it out of garage and drive down the street while the car is warming up it will shift fine but because I am just cruising and feathering the pedal when it shifts up into the higher gears it starts searching and the RPM's bounce up and down just a few hundred RPM's.. I am pretty sure it's the tranny shifting because I "think" I can feel it.. and when it warms up it's gone.. Any ideas? I do notice the car goes from about 90% smooth normally to maybe 80% when it's cold, a very slight difference, but I've seen many cars do that when cold.. I don't see how that could be related.. anyway, thanks for help!
