1. Replace the O-ring with a new one. Apply AT fluid to the new O-ring and then install it in the low clutch piston.
2. Be careful not to twist or misalign out the O-ring when inserting the low clutch piston.




Note: Note the direction of the cushion plate.

3. Assemble with cushion plate periphery touching the low clutch.
4. Be sure to assemble the low clutch plate set components in the right order as indicated.

Note: If the application limit is exceeded, replace the friction plates (10) and the separator plates (4) with new ones, and select a suitable retaining plate so that specified clearance will be obtained.

Note: If clearance is less than the application limit, select a suitable retaining plate (3) so that the clearance will fail within the desired range.

1. Using a thickness gage (1), measure the clearance between the snap ring and the retaining plate (2).

Clearance Specification
Specification standard is 0.8 - 1.1 mm (0.03 - 0.04 in).
