I just bought a 2000 328ci last week and already have an internittent
reverse problem with the trans. The transmission is the automatic steptronic
and apparently is a sealed system with no dipstick. At times, the reverse
is just like another neutral. When the reverse works it pulls very well. All
forward gears pull well and shift smoothly also. The car has 92K miles on it
and I have read lots of accounts of owners with similar symptoms.
Any suggestions on this? I am an ex-aircraft mechanic and was hoping I could
perform oil changes and periodic service myself. Am hoping I am not looking
at a $5k trans replacement
I appreciate any advice
yes, the indicator does change and displays 'R" properly.
One of the search results I read stated that there was a motion solenoid
that locks out the torque converter in reverse. If I remember correctly it
supposedly locks out the torque converter (and thus reverse) during forward
motion of speeds over 3MPH. He went on to say something about testing the
trans in safe mode to confirm this was what was causing the problem.
Other people describing the same symptoms report that reverse was restored
after a transmission servicing. Maybe thats where I need to start? I
probably need to get a manual on this car as I have factory manuals on all
my vehicles. I just didnt think I was going to need one so soon.
With the exception of resetting the oil service light, can a guy change the
oil and service the transmission on these cars in his own garage?
I appreciate the response
