So I'm pretty sure I'm buying a parts car. It was a running driving 94 auto. It now has a blown Trans. My currant car is a 95 manual. i think my ecu may be back. Will the auto one work enough to start and test drive car. I plan to replace with correct one if mine is bad just want to use as a test unit. Also my odometer needs gears to work. Can I just swap clusters or are they different between manual and autos. Thanks for the help.
