GM Storm/Spectrum 1985-1993 Repair Guide



The manual transaxle used on the Spectrum and the Storm is the Isuzu-built 76mm five speed manual unit. All forward gears on the 76mm unit are in constant mesh. The reverse gear uses a sliding idler gear arrangement. The final output gear is an integral part of the output shaft. It turns the ring gear and the differential assembly, which turns the drive axle shaft to power the front wheels.

The transaxle uses a cable to control the clutch. The cable runs from the pedal through two brackets in the rear of the engine compartment. The cable snaps into the clutch lever forward of the second bracket.
