Certain medium duty tilt cab trucks equipped with manual transmissions have a condition in which the clutch master-cylinder pushrod end that attaches to the clutch pedal pin can wear prematurely. the first noticeable effect of this wear could be the clutch pedal not returning completely to the full-up position.
Risk and remedy
Risk
If this occurs, the fast-idle engine speed control may not function. if the clutch master-cylinder pushrod end wears sufficiently to allow the attaching end to bend open or break off, the pedal pin would detach from the clutch rod link and the clutch would engage. if clutch engagement occurred while the vehicle was stopped, with the engine running and the transmission in gear, and if the brakes were not applied, the vehicle could move forward if the transmission were in a forward gear, or rearward if the transmission were in a reverse gear.
Remedy
Dealers will install a new clutch master-cylinder assembly and clutch pedal assembly. owner notification began april 23, 2002. owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1-800-222-1020 or GMC at 1-800-462-8782.
