ton.
4. Install the piston in the clutch drum. Apply pressure

and rotate to ensure proper seating.

NOTE: Lubricate the piston O-ring with ATF before

installing.

CAUTION: Do not pinch O-ring by installing the

10. Install the disc spring.

NOTE:

• For 1st-hold and 2nd clutches.

• Install the disc spring in the direction shown.
13. Install the snap ring.

11. Soak the clutch discs thoroughly in ATF for a mini-

mum of 30 minutes.

12. Starting with a clutch plate, alternately install the

clutch plates and discs. Install the clutch end plate

with flat side toward the disc.

NOTE: Before installing the plates and discs, make

sure the inside of the clutch drum is free of dirt or

other foreign matter.ProCarManuals.com

14. Measure the clearance between the clutch end plate

and top disc with a dial indicator. Zero the dial indi-

cator with the clutch end plate lowered, and lift it up

to the snap ring. The distance that the clutch end

plate moves is the clearance between the clutch end

plate and top disc.

NOTE: Measure at three locations.

a new clutch end plate from the following table.

but the clearance is still over the standard, replace
