CAUTION: All gears and shafts must not be interchanged with other transaxles; they will not function cor-
rectly.
The differential is a conventional arrangement of gears that is supported by tapered roller bearings. The final output
gear turns the ring gear and differential assembly, thereby turning the drive axle shafts.
GEARSHIFT PATTERN
The T355 transaxle shift pattern is a modified H–pat-
tern. Overdrive fifth and reverse gears are in-line and
outboard of the first through fourth gear positions.
DIAGNOSIS AND TESTING
COMMON PROBLEM CAUSES
The majority of transaxle malfunctions are a result of:
•
Insufficient lubrication
•
Incorrect lubricant
•
Mis-assembled or damaged internal components
•
Improper operation
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.
Mis-assembled synchronizer components also cause shifting problems. Incorrectly installed synchronizer sleeves,
struts, or springs can cause shift problems.
Worn, damaged, mis-assembled or leaking hydraulic clutch release system/components can also cause difficult
shifting or gear clash.

NOISY OPERATION
Transaxle noise is most often a result of worn or damaged components. Chipped, broken gear or synchronizer
teeth, and brinnelled, spalled bearings all cause noise.
Abnormal wear and damage to the internal components is frequently the end result of insufficient lubricant.
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 also causes gear disengagement.
LOW LUBRICANT LEVEL
Insufficient transaxle lubricant is usually the result of leaks, or inaccurate fluid level check or refill method. Vehicle
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 underfill.
If air–powered lubrication equipment is used to fill a transaxle, be sure the equipment is properly calibrated. Equip-
ment out of calibration can lead to an underfill 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 release bearing can cause hard shifting and gear clash.
