PRECAUTIONSPFP:00001
Service Notice or PrecautionsECS008BM
Do not reuse transaxle oil, once it has been drained.
Check oil level or replace oil with vehicle on level surface.
During removal or installation, keep inside of transaxle clear of dust or dirt.
Check for the correct installation status prior to removal or disassembly. If matching mark are required, be
certain they do not interfere with the function of the parts they are applied.
In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, use it.
Be careful not to damage sliding surfaces and mating surfaces.

Changing M/T OilECS008BR
DRAINING
1. Start engine and let it run to warm up transaxle.
2. Stop engine. Remove drain plug and then drain oil.
3. Set a gasket on drain plug and install it to transaxle case. Tighten drain plug to the specified torque. Refer
to MT-22, "
Case and Housing Components" (RS5F51A) or MT-40, "Case and Housing Components"
(RS6F51A).
CAUTION:
Do not reuse gasket.
FILLING
1. Remove plug (for 2WD models) or filler plug (for 4WD models).
Fill with new oil to transaxle.
2. After refilling oil, check oil level.
3. Set a O-ring on plug (for 2WD models) or gasket on filler plug
(for 4WD models) and then install it to clutch housing.
CAUTION:
Do not reuse O-ring or gasket.
4. Tighten plug mounting bolt (for 2WD models) or filler plug (for 4WD models) to the specified torque. Refer
to MT-22, "
Case and Housing Components" (RS5F51A) or MT-40, "Case and Housing Components"
(RS6F51A).
Checking M/T OilECS008BS
OIL LEAKAGE AND OIL LEVEL
Make sure that oil is not leaking from transaxle or around it.
Remove plug (for 2WD models) or filler plug (for 4WD models).
Measure oil level using a suitable gauge as shown in the figure, and then check if it is within the specifica-
tions.
CAUTION:
Do not start engine while checking oil level.
–For 2WD modelsOil grade and viscosity: Refer to MA-17, "
Fluids and
Lubricants" .
Oil capacity (reference):
Approx. 2.2 (3-7/8 lmp pt)

SIDE OIL SEALPFP:32113
Removal and InstallationECS008BT
REMOVAL
Clutch housing side oil seal used on 4WD vehicles is attached to transfer. Be sure to replace it
when transfer is removed.
1. Remove drive shaft from transaxle. Refer to FAX-11, "
Removal and Installation" .
2. Remove oil seal with a flat-bladed screwdriver.
CAUTION:
Be careful not to damage the case surface when removing
oil seal.
INSTALLATION
1. Using the drift, drive the oil seal straight until it protrudes from
the case end equal to dimension A shown in the figure.
CAUTION:
Apply multi-purpose grease onto oil seal lip. (For clutch
housing side of 4WD models)
Do not reuse oil seal.
2. Install all parts in the reverse order of removal and check oil
level after installation. Refer to MT-12, "
Checking M/T Oil" .

17. Remove transaxle assembly from the vehicle.
CAUTION:
Secure transaxle assembly to a jack while removing it.
INSTALLATION
Note the following, and install in the reverse order of removal.
When installing the transaxle assembly to the engine, install the mounting bolts following the standard
below.
CAUTION:
When installing transaxle assembly, be careful not to bring transaxle input shaft into contact with
clutch cover.
–QR engine models
*: Tightening the bolt for 4WD models.
–YD engine models
After installation, check oil level, and check for leaks and loose
mechanisms. Refer to MT-12, "
Checking M/T Oil" .
