TRANSAXLE ASSEMBLY
• When installing the torque converter to the transaxle measure dis-
tance A.
• When installing the cooler outlet tube (1) to the transaxle assembly (2), align the cooler tube bracket (A) against the transaxle as
shown.
• When installing the transaxle to the engine, align t he matching mark on the drive plate with the matching
mark on the torque converter alignment stud.
• When securing the transaxle to the engine, attach the bolts in accordance with the following standard.
• When installing the drive plate to torque converter nuts, tighten them temporarily. Then tighten the nuts to the specified torque.
• After completing installation check for fluid level, fluid leakage, and the positions of CVT. Refer to CVT-14,
"Checking CVT Fluid", CVT-164, "Adjustment of CVT Position" and CVT-164, "Checking of CVT Position".
• When replacing the CVT assembly, erase EEP ROM in TCM. Refer to CVT-8, "
Service After Replacing TCM
and Transaxle Assembly".

Self-Diagnosis Mode of Combination MeterINFOID:0000000005929166
SELF-DIAGNOSIS MODE FUNCTION
• Self-diagnosis can check for continuity between meter control circuit and each meter (speedometer, tachom- eter and fuel gauge).
• Self-diagnosis can check for odo/trip meter and A/T indi cator (with A/T) or CVT indicator (with CVT) seg-
ment, low-fuel level warning lamp, low water temperature indicator lamp, and high water temperature warn-
ing lamp.
OPERATION PROCEDURE
1. Turn the ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”. NOTE:
