TRANSMISSION K Assembly procedure 1. Apply ATF to a new O-ring and install it onto the piston. 2. Apply ATF to a new seal ring and install it onto the piston. 3. Apply even pressure to the perimeter of the low and re- verse brake piston, and install it into the transmission case. 4. Verify that the piston can be turned by hand. If it cannot, then remove it and check for damage to the seal ring and O-ring. 5. Apply ATF to the one-way clutch inner race, thrust wash- er, and return spring. 6. Assemble the one-way clutch inner race, thrust washer, and return spring, and install them in the transmission case. 7. Verify that the return spring, thrust washer, and rings are properly positioned before securing the bolts. RETURN SPVING THRUSTWASHER 45UOKX-291 8. Tighten the allen head bolts by using the SST.
