Minimum

1.45 mm {0.057 in}

• If not within the specification, replace the drive plates.

Caution

• Installing the low and reverse brake piston may damage its seal. Carefully install the low and 

reverse brake piston by pushing evenly around the circumference.

2. Apply ATF to the circumference of the low and reverse brake piston seal, and install the piston to the transaxle 

case.

3. Install the piston return spring and one-way clutch 

to the transaxle case.

4. Install the SSTs as shown.
