Question type: General

My manual tranny keeps acting up and I am tired of the clutch issues.  How hard of a swap is it?  Are they compatible?

I believe the bolt pattern is a little different. However, the same 3 speed auto came on both engines for the duration of the vehicle's life so it should be possible to find a v6 auto. alternatively, you could look into another auto that shares the same bolt pattern. Keep in mind you will also need to make computer changes to get everything to work right since your manual doesn't shift itself and likely doesn't have any programming related to the transmission.

Check out GAOwnersClub.com - There a guy who posts there that installed a V6 engine in his Fiero.
