where is TCM(transmission control module) located?
My 94 325is has developed a tranny issue.
Oftenly auto tranny sticks on 1st or 3rd gear and never shift up until I manually downshift it to '3' and put it back to 'D'.
I've been searching for this issue and found some posts regarding this.
most of them said that TCM(transmission control module) needs to be replaced or reprogrammed.
What i'd like to know is
1. where is the TCM located?
2. is it possible task for a weekend mechanic(me)?
3. if not, how much would it cost at an independant bmw shop or AAMCO or even dealer$hip?
thnx in advance.
