TRANSAXLE ASSEMBLY
Revision: June 20062007 Versa
4. Remove the four drive plate to torque converter nuts.
NOTE:
Rotate the crankshaft clockwise as 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 transaxle to engine and engine to transaxle bolts.
7. Separate the transaxle from the engine.
8. If necessary, remove the following from the transaxle:

CVT fluid charging pipe

Engine mounting bracket (LH)

Fluid cooler tubes

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 and copper washers.

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. Refer to EM-37, "
TIMING
CHAIN" .

After converter is installed to drive plate, rotate crankshaft several turns to check that transaxle
rotates freely without binding.

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

When installing the cooler outlet tube (1) to the transaxle assem-
bly (2), align the cooler tube bracket (A) against the transaxle as
shown.

When installing the transaxle to the engine, align the 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-16,
"Checking CVT Fluid" , CVT-195, "Adjustment of CVT Position" and CVT-196, "Checking of CVT Posi-
tion" .

When replacing the CVT assembly, erase EEP ROM in TCM. Refer to CVT-9, "Service After Replacing
TCM and Transaxle Assembly" .
