The Pontiac Fiero that is equipped with a manual transaxle uses one of three types. The early fieros were equipped with either a 4-speed 76mm Isuzu or 5-speed 76mm Isuzu transaxles. The external components are basically the same with the differences in the internal components. The later model Fieros came equipped with 5-speed 282 Muncie transaxles. This model trans has been redesigned to conform with the increased horsepower ratings of the newer engines.

The manual transaxle uses a hydraulic clutch system that supplies hydraulic pressure to the slave cylinder to actuate the clutch assembly.

Two cable assemblies are used to shift the gears, one being the transaxle selector cable and the other a transaxle shifter cable. The cables are routed rearward through the floor pan extension. They are anchored to the transaxle and floor pan through the use of clips.

The identification tag is located on the transaxle bell housing. The 4 and 5-speed Isuzu transaxles have the tag on the side of the bell housing. The 5-speed Muncie transaxles have the tag on the top of the bell housing.
