way.
CAUTION:
• Perform this step when the engine is cold.
• When replacing TCM and transaxle assembly as a set, replace transaxle assembly first and then
replace TCM. Refer to

• Align the torque converter stud bolts (B) and drive plate holes.
- When using a suitable tool (A), set it to the alignment stud bolt
which is used to align the torque converter to the drive plate.
- Rotate torque converter so that the alignment stud bolt aligns with
the position of the service hole
• Rotate crankshaft so that the hole (A) for inserting alignment stud
bolt of drive plate aligns with the service hole (B).
- When not using suitable tool for alignment, insert stud bolt of
torque converter into the hole (C) of drive plate, aligning the drive
plate hole position and torque converter stud bolts.
CAUTION:
Be careful not to strike the drive plate when installing the
torque converter stud bolt.
• When installing the torque converter nuts temporarily tighten the
nuts. Then, after installing the engine and transaxle assembly bolts
tighten the nuts to the specified torque.
