Do not remove the radiator cap when the engine is hot. Serious burns could occur from high pressure
coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter turn to
allow built-up pressure to escap e. Carefully remove the cap by turning it all the way.
CAUTION:
• Perform when the engine is cold.
• When replacing TCM and transaxle assembly as a set, replace transaxle assembly first and then
replace TCM. Refer to TM-81, "Description"

TRANSAXLE ASSEMBLY
1. Remove the engine and transaxle with the front suspension member as a unit. Refer to
EM-220,
"Removal and Installation".
2. Disconnect the transaxle harness connectors.
3. Disconnect the CVT oil warmer water hoses from engine side. Refer to TM-400, "WATER HOSE :
Removal and Installation".
4. Remove the CVT fluid charging pipe.
5. Remove the transaxle to engine and engine to transaxle bolts.
6. Separate the engine from the transaxle and remove the engine from the front suspension member. Refer to EM-220, "Removal and Installation"
.
NOTE:
Using paint, put matching marks on the drive plat e and torque converter when removing the torque con-
verter to drive plate nuts.
7. Remove transmission bracket.
8. Lift the transaxle from the front suspension member.
INSTALLATION
Installation is in the reverse order of removal.
NOTE:
Write down the serial number of the new transaxle assembly.
CAUTION:
• When replacing an engine or transaxle you must m ake sure any dowels are installed correctly during
re-assembly
• Improper alignment caused by missing dowels m ay cause vibration, oil leaks or breakage of drive
train components.
• Do not reuse O-rings or copper sealing washers.
• When turning crankshaft, turn it clockwi se as viewed from the front of the engine.
• When tightening the nuts for the torque converte r while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-174, "Removal and Instal-
lation".
• After converter is installed to drive plate, rota te crankshaft several turns to check that CVT rotates
freely without binding.
• When installing the CVT to the en gine, align the matching mark on the drive plate with the matching
mark on the torque converter.
When installing CVT assembly to th e engine assembly, attach the bolts in accordance with the follow-
ing standard.
