Transmission conversion

[egirard]

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!!!

Thats partially why Isuzu's did not come on V6's. 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

I am using the stock arm on mine. I just shaved it down to were the slave connects. (about 1.5") and it works fine now.

cheers!

Thanks for the info.

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!

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.

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!
