COMPONENTS











REMOVAL

WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure coolant escaping from the radiator.

CAUTION:
- Perform this step engine is cold.
- When replacing TCM and transaxle assembly as a set, replace transaxle assembly first and then replace TCM. Service After Replacing TCM, Transaxle Assembly, Or Control Valve.
1. Remove the engine and transaxle as an assembly. Removal And Installation.





2. Disconnect the electrical connectors from the following:
- Secondary speed sensor (1)
- Primary speed sensor (2)
- CVT unit connector (3)
- Transmission range switch (4)
3. Remove the harness from the CVT.





4. Remove the four drive plate to torque converter nuts.

NOTE:
Rotate the crankshaft clockwise viewed from front of engine for access to drive plate to torque converter nuts.
5. Put matching marks on the drive plate and torque converter alignment stud.

CAUTION:
For matching marks, use paint. Never damage the drive plate or torque converter.
6. Remove the CVT to engine and engine to CVT bolts.
7. Separate the CVT from the engine.
8. If necessary, remove the following from the CVT:
- Primary speed sensor
- Secondary speed sensor
- Transmission range switch
- CVT fluid charging pipe
- Engine mounting bracket (LH)
- Water tube and hoses
- Air breather hose
- Any necessary brackets

INSTALLATION
Installation is in the reverse order of removal.

CAUTION:
- 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.
- When turning crankshaft, turn it clockwise as viewed from the front of the engine.
- When tightening the nuts for the torque converter while securing the crankshaft pulley bolt, be sure to confirm the tightening torque of the crankshaft pulley bolt. Component.
- After converter is installed to drive plate, rotate crankshaft several turns to check that CVT rotates freely without binding.
- When installing the CVT to the engine, align the matching mark on the drive plate with the matching mark on the torque converter alignment stud.





- When installing CVT 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.






INSPECTION BEFORE INSTALLATION





When installing the torque converter to the CVT measure distance A.






INSPECTION AFTER INSTALLATION
Check the following.
- Check for CVT fluid leakage and check CVT fluid level. Procedures.
- Check CVT position. Shift Control System.
- Start and warm up the engine. Visually check that there is no leakage of engine coolant and CVT fluid.

ADJUSTMENT AFTER INSTALLATION
Erase TCM data.
- Erase CVT fluid degradation level data. CVT Trouble Diagnosis.
- When replacing the transaxle assembly, erase EEP ROM in TCM. Service After Replacing TCM, Transaxle Assembly, Or Control Valve.
