Checking A/T FluidINFOID:0000000005928070
1. Warm up engine.
2. Check for A/T fluid leakage.
3. Before driving, A/T fluid level can be checked at A/T fluid tem- peratures of 30° to 50°C (86° to 122° F) using the “COLD” range
on A/T fluid level gauge.
• A : Front side
• B : Reverse side
•C : Add
• D : OK
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi- tion. Leave selector lever in “P” position.
c. Check A/T fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free cloth. CAUTION:
When wiping the A/T fluid l evel gauge, always use lint-free
cloth.
e. Re-insert A/T fluid level gauge into A/T fluid charging pipe as far as it will go.
CAUTION:
Firmly fix the A/T fluid level ga uge to the A/T fluid charging
pipe using the stopper attached.
f. Remove A/T fluid level gauge and note reading. If reading is at low side of range, add A/T fluid to the A/T fluid charging pipe.
CAUTION:
Do not overfill.
4. Drive vehicle for approximately 5 minutes.
5. Re-check A/T fluid level at A/T fluid temperatures of 50° to 80 °C (122° to 176°F) using “HOT” range on A/
T fluid level gauge.
CAUTION:
• When wiping the A/T fluid level gauge, always use lint-free cloth.
• Firmly fix the A/T fluid level ga uge to the A/T fluid charging pipe using the stopper attached.
6. Check A/T fluid condition and make any necessary repairs. Refer to AT-51, "
Inspections Before Trouble
Diagnosis". If the A/T fluid contains frictional material (clutches, bands, etc.), or if the A/T is repaired, over-
hauled, or replaced, inspect and clean the A/T fluid cooler mounted in the radiator. Refer to AT-18, "
A/T
Fluid Cooler Cleaning".
7. Install the removed A/T fluid level gauge into the A/T fluid charging pipe. CAUTION:
Firmly fix the A/T fluid level gaug e to the A/T fluid charging pipe using the stopper attached.
Changing A/T FluidINFOID:0000000005928071
1. Warm up A/T fluid.
2. Stop engine.
3. Drain A/T fluid by removing the drain plug. Re install the drain plug to the specified torque.
CAUTION:
Do not reuse drain plug gasket.
4. Refill the transaxle with new specified A/T fluid through the A/T fluid charging pipe. Always refill the tran- saxle with the same volume of A/T fluid that was drained out.

•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 brake At 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 brake Front 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 brake As there is no one-way clutch in the power transaxle line, engine brake can be obtained
when decelerating.

REMOVAL AND INSTALLATION
Removal
1. Remove front drive shaft. Refer to FA X - 9.
2. Remove differential side oil seals using a suitable tool. CAUTION:
Be careful not to scratch transaxle case and converter
housing.
Installation
Installation is in the reverse order of removal.
NOTE:
• Drive each differential side oil seal evenly using Tools (Transaxlecase side only) and suitable tool (Convertor housing side only) so
that differential side oil seal prot rudes by the dimension (C) or (D)
respectively.
(1): LH differential side oil seal
(2): RH differential side oil seal
(A): Transaxle case side
(B): Converter housing side
Unit: mm (in)
NOTE:
• Differential side oil seal pulling direction is used as the reference.

• 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 th e torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-159
.
• After converter is installed to drive plate, ro tate 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
• When installing the transaxle to the engine, align the matching mark on the drive plate with the matching mark on the torque converter.
