TRANSMISSION DIAGNOSTICS

HARD SHIFTING

SYSTEM DIAGNOSIS
Difficulty shifting, or harsh shifting are generally caused by the Transmission or PVT Systems. The system causing the
difficult shifting concern can generally be diagnosed using the following information.
SYMPTOM
Vehicle is difficult to shift ONLY with the engine running
Vehicle is difficult to shift all the time
ADDITIONAL HARD SHIFTING CAUSES
• Shift cable adjustment/condition
• PVT alignment (clutch center distance)
• Transmission lubricant type/quality
• Transmission leaks / fluid level

TRANSMISSION ISOLATION

To determine if shifting difficulty or problem is caused by an internal transmission problem or external concern the
transmission should be isolated using the following information.
After the transmission is isolated refer to Additional Shifting Causes or the proper chapter in the service manual for
additional information.
1. Disconnect the shift cable from the bellcrank.
2. With the shift cable disconnected from the transmission shift the vehicle using the shift lever.
• If the shift lever continues to bind the concern is likely caused by the shift cable. Refer to the proper service
information for replacement.
• If the shift lever moves freely proceed to step 3.
3. With the shift lever disconnected manually select each gear range at the transmission bellcrank.
• If the bellcrank requires more than approximately 15 ft-lbs (20 N·m) to rotate, the shifting concern is most likely
caused by an internal transmission concern.
• If the bellcrank moves freely, manually select each gear range at the transmission bellcrank and test ride vehicle.
If it functions properly then there is likely still an outside concern causing the issue.
