Transaxle Troubleshooting

Print

It is generally acknowledged that the Volkswagen transaxle is one of the most durable parts of the automobile. Any well-treated VW transaxle is capable of well over 100,000 trouble-free miles. In the event, however, that an owner should have transaxle problems, here are some problems along with their possible causes:

CAR IS NOISY WHILE MOVING IN ANY GEAR


Insufficient lubrication
 
One or more worn bearings in the transaxle
 
Mainshaft end-play excessive
 
Sliding gears worn or broken
 
Misalignment of transxle case or clutch housing
 

TRANSAXLE SLIPS OUT OF GEAR


Improper shifting procedure
 
Worn shift detent parts
 
Shift linkage improperly adjusted
 
Misalignment between the transaxle and the engine
 

TRANSAXLE NOISY IN NEUTRAL


Insufficient lubrication
 
One or more worn gears or bearings
 

TRANSAXLE DIFFICULT TO SHIFT


Shift linkage improperly adjusted
 
Clutch not releasing properly
 
Improper lubricant in transaxle
 
Binding of shift linkage due to worn or damaged parts
 

TRANSAXLE LEAKS LUBRICANT


Axle boot not sealing properly due to looseness, crack, or other damage.
 
Oil seals damaged.
 
Transaxle axle retainer nuts loose. (Do not overtighten because the retainer will then be slightly distorted and may leak more than before.)
 
Transaxle housing nuts loose.
 
Transaxle filler and/or drain plugs loose or stripped of thread.
 
Use of a lubricant that tends to foam excessively.
 
Excessively high transaxle oil level.
