Title: Transmission conversion Post by: egirard on July 11, 2004, 07:34:39 pm Hi Guys,
I am doing an automatic to standard conversion on my Fiero GT v6 86 with an Isuzu transmission (the 4 cyl. 5 speeds transmission), but I have a little problem. After the installation of the crossover pipe (the Y exhaust pipe), I found out that the clutch level, (the arm that the slave cylinder push to release the clutch) is blocked by the crossover pipe :-[. The clutch level is the original one (the two pieces stamped steel). If I buy the one piece cast iron, will my problem be fixed? Will it be better to buy the V6 4 speeds instead of buying the original one (4 cyl. 5 speeds for Isuzu)? Thanks for your help!!!

It can be gotten around but I would reccomend getting an 84 model 332 econo 4 speed and everything will work fine and rev lower in high gear. Plus the muncie 4 speed is a stronger tranny. Dan

The arm is too rusted to cut, so I ordered a new one. Two last questions: After the conversion, have your speedometer shown the true speed? Also, when you have modified your car, have you grounded the park-neutral input on the ECM? Thanks again for your help! ;) Eric Title: Re: Transmission conversion Post by: dguy on July 15, 2004, 09:10:06 am After the conversion, have your speedometer shown the true speed? Assuming that they're both Fiero transmissions, the easiest way to do ensure that your speedo/odometer is still calibrated correctly is to transfer the VSS which is in your automagic transmission to the manual.

Yes, as i used the plastic gear that came with the VSS on the donor car. ;) >>Also, when you have modified your car, have you grounded the park-neutral input on the ECM? EEEEK! Gawd no! there is a park neutral safety switch positive and negative. The right way to do it: Run wires into the car, up to clutch switch, the Eric way: Posi to negative to complete the circuit. Just don't start the car in gear! Cheers! Eric Title: Re: Transmission conversion Post by: egirard on August 02, 2004, 08:17:41 am It works ! ;D
