REPLACE
1. Disconnect battery ground cable, then raise and support vehicle.
2. Remove six bolts and left splash shield from vehicle.
3. Place a drain pan or suitable container under transaxle fluid pan, then remove drain plug, drain transaxle fluid and remove transaxle fluid pan.

CAUTION: When removing transaxle fluid pan, use caution to not damage mating surfaces. Use a rubber mallet and wooden block if pan is frozen to transaxle; do not use metal objects (crow bar, screwdriver, etc.) to free pan.

4. Remove filter and screen from valve body, then disconnect solenoid electrical connectors from shift solenoid Nos. 1 and 2 and TCC solenoid, Fig. 2 .
5. Remove bolt and solenoid wire harness clip from valve body, then detent spring.
6. Remove TV cable from throttle valve cam. The B2 accumulator, check ball and spring may drop from transaxle during valve body removal. The B2 accumulator is under intense spring pressure and may push valve body down after valve body bolts are loosened.
7. Remove 17 bolts, Fig. 3 , and valve body from transaxle while simultaneously disconnecting manual valve link from manual lever.
8. Remove check ball body and spring from transaxle, then B2 accumulator piston and spring. When using compressed air to remove components from transaxle case, air pressure should never exceed 14 psi.

9. Remove C2, C1 and C3 accumulator pistons and springs from transaxle case by slowly applying low pressure compressed air into accumulator apply passages, Fig. 4 through 6 .
10. Reverse procedure to install. Prior to installation, inspect transaxle case for nicks or scars, accumulator seals for cuts or damage and accumulator pistons for cracks or porosity.
