Abnormal Noise
Transaxle noise is most often a result of worn or damaged components. Chipped, broken gear or synchronizer teeth,
and worn bearings all cause noise.
Inspect for the following:
• Insufficient lubrication
• Incorrect lubricant
• Mis-assembled or damaged internal components
• Improper operation
Symptom Diagnostics
Hard Shifting
• Hard shifting may be caused by a mis-adjusted crossover cable. If hard shifting is accompanied by gear clash,
synchronizer clutch and stop rings or gear teeth may be worn or damaged.
Slips Out Of Gear
• Transaxle disengagement may be caused by misaligned or damaged shift components, or worn teeth on the
drive gears or synchronizer components. Incorrect assembly of the transaxle could also cause gear disengage-
ment.
Low Lubricant Level
• Insufficient transaxle lubricant is usually the result of leaks, or inaccurate fluid level check or refill method. Vehi-
cle must be level to accurately check fluid level. Leakage is evident by the presence of oil around the leak
point. If leakage is not evident, the condition is probably the result of an under fill.
• If air–powered lubrication equipment is used to fill a transaxle, be sure the equipment is properly calibrated.
Equipment out of calibration can lead to an under fill condition.
Clutch Problems
• Worn, damaged, or misaligned clutch components can cause difficult shifting, gear clash, and noise.
• A worn or damaged clutch disc, pressure plate, or a faulty slave cylinder can cause hard shifting and gear
clash.
Abnormal Noise
• Transaxle noise is most often a result of worn or damaged components. Chipped, broken gear or synchronizer
teeth, and worn bearings all cause noise.
Inspect the following:
