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 & reverse clutch piston.

Note: Note the direction of the cushion plate.




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

5. Be careful not to distort the spring retainer when using DT 47526  (1).
6. Ensure that the snap ring fits snugly in the drum groove.
7. Ensure that the snap ring opening is not aligned with the stopper.
8. Ensure that the snap ring opening is aligned with the concave aperture.
9. Before using a new low & reverse brake plate set, soak it in AT fluid for more than 2 hours.

Note: If the application limit is exceeded, replace the friction (9) and separator plates (4) with new ones, and select a suitable retaining plate (10) so that the specified clearance will be obtained.

If the clearance is less than the application limit, select a suitable retaining plate (10) so that the clearance will fall within the desired range.
1. Using a thickness gage (2), measure the clearance between the snap ring and the retaining plate (10).

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

Clearance Specification
Specification application limit is 1.3 mm (0.05 in).
