Models: 1995 - l997 (BR) Ram Trucks V10 Manual

NOTE: THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH AN 8.0L ENGINE AND MANUAL TRANSMISSION.

Symptoms:

Gear rattle may occur when ambient temperatures are high, the transmission is at operating temperature and the vehicle operator accelerates in 4th or 5th gear from approximately 30 to 55 mph.

Neutral gear rattle may occur when ambient temperatures are high, the transmission is at operating temperature with the engine idling, and the transmission in neutral with the clutch pedal released.

With the vehicle fully warmed-up and stopped, apply the parking brake. With the transmission in neutral and the engine at idle, depress and release the clutch pedal (disengage and engage the clutch). If the gear rattle sound goes away when the clutch pedal is depressed and held down, perform the Repair Procedure.
