Hi all,
I hope someone can shed some light on this problem as its got me! I recently bought a 1987 M535i with the switchable automatic gearbox. I have discovered that when the car is cold it doesnt want to change gears properly. I think it manages to drop into second gear but refuses to go into third although at about 2500rpm there is a second of hesitation as if it was going to change but decided not to. If its in sports mode it seems to cope with better as doesnt need much to get it to 40mph until its warmed up and then it behaves and changes gears as normal for the rest of the journey.
The other weird part is when I come to a stop if I engage neutral it still stays in drive while this other problem is happening, but again when its warmed up it works fine. Any ideas anybody please as I have no idea where to begin??? Im thinking maybe an electrical fault as the wiring in the car was less than perfect to start with and I did have fuses popping and even the heater fan has died although I have a replacement ready to fit.
Thanks,
Dan.
