GENERAL INFORMATION (Continued)
All JA transaxles have a torque capacity of 136 lb.
ft. The gear ratios of each transaxle are shown in the
following chart. The chart also shows which transax-
les are available with the reverse–input shaft brake.
This brake allows easier shifting into reverse and
helps eliminate reverse gear clash.

DESCRIPTION AND OPERATION

GEARSHIFT LEVERS

The shift levers are serviceable in the vehicle. The
shift levers are different from each other and do not
interchange.

AXLE SEALS

The axle shaft seals are identical for both sides of
the differential and will interchange.

NOISY OPERATION

cause noise.

lubricant.

SLIPS OUT OF GEAR

aligned or damaged shift components, or worn teeth
on the drive gears or synchronizer components. Incor-
rect assembly also causes gear disengagement.

LOW LUBRICANT LEVEL

result of leaks, or inaccurate fluid level check or refill

around the leak point. If leakage is not evident, the
condition is probably the result of an underfill.
