•High clutch
•Brake band
•Forward clutch (Does not affect power
transmission)Input power is transmitted to front carrier through high clutch.
This front carrier turns around the sun gear which is fixed by brake band and makes
front internal gear (output) turn faster.
Engine brakeAt D
4 position, there is no one-way clutch in the power transaxle line and engine brake
can be obtained when decelerating.

•Reverse clutch
•Low & reverse brakeFront planetary carrier is stationary because of the operation of low and reverse brake.
Input power is transmitted to front sun gear through reverse clutch, which drives front
internal gear in the opposite direction.
Engine brakeAs there is no one-way clutch in the power transaxle line, engine brake can be obtained
when decelerating.

TRANSAXLE ASSEMBLY
• When replacing an engine or transmission you must make sure any dowels are installed correctly
during re-assembly.
• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive
train components.
• Do not reuse O-rings and copper washers. Refer to "COMPONENTS".
• When turning crankshaft, turn it clockwise as viewed from the front of the engine.
• When tightening the bolts for the torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-37
.
• After converter is installed to drive plate, rotate crankshaft several turns to check that transaxle
rotates freely without binding.
• When installing the torque converter to the transaxle measure dis-
tance A.
• Check the fitting of the dowel pins when installing the transaxle
assembly and the engine assembly.
: Dowel pin (2)
• When installing the transaxle to the engine, align the matching mark on the drive plate with the matching
mark on the torque converter.
• When securing the transaxle to the engine, attach the bolts in
accordance with the following standard.
(A): A/T to engine
(B): Engine to A/TDimension A: 14.4 mm (0.567 in) or more

37. Remove front planetary carrier and low one-way clutch according to the following procedures.
a. Remove snap ring using a flat-bladed screwdriver.
b. Remove low one-way clutch (1) and front planetary carrier (2) as
a set from transaxle case.
c. Check that low one-way clutch rotates counter-clockwise around
front planetary carrier. Then try to turn it clockwise and check
that it is locked.
•Replace low one-way clutch if necessary.
d. Remove low one-way clutch from front planetary carrier by turn-
ing it in the direction of unlock.
•Inspect low one-way clutch, and replace if damaged or
worn.
e. Remove needle bearing (1) from front planetary carrier (2).
•Inspect needle bearing (1) and front planetary carrier (2),
and replace if damaged or worn.
