I have 2 transmissions forsale. The regular 4.10 found in most 84 manual fiero's plus I have the rare econo transmission forsale (3.32). This transmission is set up almsot like the Isuzu 5spd but it doesn't have the isuzu's 4th gear. This would a good tranny to mate with a V8 or for the person with an 84 that hates the drone from a duke at 4000rpms while trying to cruise at 120km/h.
When my coupe was running, I could cruise at 100km/h turnning 1900rpms and at 160km/h it was turnning 3000rpms and the car still had more pull (4 cylinder)
e-mail me if your intreseted. Money will be going to a good cause by putting my new fiero on the road.

here's a link to gear ratio's chart for Fiero's:
