The manual shifter allows the driver to select gears by moving the shifter inside the passenger compartment. Because the Fiero transmission is mounted behind the passenger compartment, the shifter operates the transmission through shift cables rather than direct linkage. == Overview == Manual-transmission Fieros use a floor-mounted shifter located in the cen..." current

Grinding during shifting does not automatically mean the transmission is ruined. In many Fieros, gear grinding is caused by incomplete clutch release, clutch hydraulic problems, shift cable issues, or driver technique rather than internal transmission failure. == Overview == Manual-transmission Fieros use a clutch, hydraulic clutch system, shifter, shif..." current

The clutch pedal is an important part of the Fiero clutch system. If the pedal is bent, worn, incorrectly assembled, or does not move the clutch master cylinder far enough, the clutch may not fully disengage. == Overview == Manual-transmission Fieros use a hydraulic clutch system.

The Fiero uses a hydraulic clutch system. Air in the system can prevent the clutch from fully releasing, causing hard shifting, grinding, or difficulty selecting gears. == Overview == Manual-transmission Fieros use hydraulic pressure to operate the clutch.

The Fiero used several different manual and automatic transaxles from 1984 through 1988. Because many Fieros have been repaired, modified, or transmission-swapped, the installed transmission should be identified directly rather than relying only on the car's model year, engine, or trim level. == Overview == Transmission identification is important..." current
