that all depends on what engine you have and the cam in your engine and your rearend gear and what you want to do with the car, once you figure that out you will have a better idea what stahl converter you need, other than that I would just put the stock converter in it.

Only one type of automatic transmission was used on the Fiero, the Turbo-Hydramatic-125C. The TH-125c is a 3 speed automatic. The C signifies that it has a torque converter clutch. In theory from a stop to cruising speed there should be a 1-2 shift a 2-3 shift. If you sense the transmission is hunting between 2 gears it is likely that the torque converter clutch is locking then releasing.
remove the transmission and torque converter. Remove the bolts from the pump (front of transmission case) and remove the pump.
