Channel Plate/Control Valve and Housing Assembly

To replace the channel plate/control valve and housing assembly (903) perform the following procedure:

1. Raise vehicle and support.





2. Place drain pan under transaxle bottom pan to catch fluid. Loosen the 16 bottom pan bolts (62) and remove bottom pan (59) and bottom pan seal (61). Refer to Figure 1. Allow transaxle to drain completely.

3. Remove left and right scavenger screens (51, 52) and seals (53) and discard. Use caution when removing seals not to score or damage the case.





4. Disconnect "5N" and "B" shift solenoids and transaxle pressure switch connectors. Refer to Figure 2.

5. Disconnect manual valve linkage clip (915). Refer to Figure 2.





6. Remove nine oil transfer plate bolts (534) and oil transfer plate (956). Refer to Figure 3.

7. Remove ten lower channel plate bolts (534), two nuts (955), lower channel plate control valve, and accumulator assembly (lower controls assembly) from transaxle. (DO NOT REMOVE indicated bolts in lower channel plate.) Refer to Figure 3.





8. Center the low reverse band and position using a 12" length of .020" shim stock. A mispositioned low reverse band during assembly will result in a no first gear/no engine braking/no reverse condition. Refer to Figure 4.

9. For transaxle models 2AJH, 3AJN, and 3ARN install lower controls assembly, P/N 8682762. For transaxle model 3AAN install lower controls assembly, P/N 8684463. Hold the new lower controls assembly to transaxle using the forward support studs to locate.





10. Hand start ten bolts and two nuts in channel plate. Bolts without flanges are located next to oil transfer plate. Torque bolts and nuts to 12 N-m (106 lbs.in.). Remove shim stock. Refer to Figure 5.

11. Install oil transfer plate and hand start nine bolts. Torque to 12 N-m (106 lbs.in.). Refer to Figure 3.

12. Connect manual valve (915) to detent lever (17). Refer to Figure 2.

13. Route wiring harness under spacer plate rib and detent lever. Connect wiring harness to "A" and "B" shift solenoids (909) and transaxle pressure switch (936). Refer to Figure 2.

14. Install left and right scavenger screen seals, and screens (51, 52, and 53). Refer to Figure 1.

15. Remove any residual transaxle fluid from gasket sealing surface of the case, the outside surface of the case, case bolts, bottom pan, and bolt holes. Use a rubber tipped air hose on the case bolt holes to remove fluid if necessary. All of the bottom pan bolts MUST be completely dry before installation.

IMPORTANT:
Failure to remove oil from oil pan, case surface, and case bolt holes, will greatly reduce the efficiency of the gasket and may cause a leak in the future.

16. Position the new gasket and bottom pan on the transaxle.

IMPORTANT
Bottom pan seal is not reusable. Install new bottom pan gasket and scavenger screen and bolt package, P/N 8684953.
