Control Valve Body Replacement

Control Valve Body Replacement

Tools Required

J 36850 Transjel

Removal Procedure

1. Remove the case side cover.




2. Remove the wiring harness as necessary.
3. Remove the oil pump.




4. Remove the valve body to channel plate bolts (374-381, 384).




5. Remove the valve body. Leave the spacer plate with the transmission.




6. Remove the spacer plate and the spacer plate gasket, as necessary.
7. Remove the solenoid screens.

Installation Procedure

Notice: The assembly of some components will require the use of an assembly lube. Always use J 36850 Transjel(TM) or petroleum jelly during assembly. Greases other than the recommended assembly lube will change the transmission fluid characteristics and cause undesirable shift conditions and/or filter clogging.




1. Inspect the control valve body spacer plate (370) for the following conditions:

* Plugged holes
* Damaged gasket sealing surfaces
* Plugged or damaged screen/seal assemblies (382)




2. Inspect each ball check valve seat one at a time on the spacer plate (370) for excessive peening.

* Place a ball check valve (372) on each seat
* Use a flashlight to look for visible light between the ball check valve and the seat.
* If light is visible between the ball check valve and the seat, replace the spacer plate assembly (370).




3. Install four ball check valves (372) into the case cover (400), in the positions shown. Use J 36850.




4. Install the two larger ball check valves (373) and the four smaller ball check valves (372) into the control valve body (300). Use J 36850.




5. Install the screen/seal assemblies (382) into the spacer plate assembly (370).
6. Install the control valve body to spacer plate gasket (371), the spacer plate assembly (370) and the case cover to spacer plate gasket (369) onto the control valve body (300).
7. Install the bolts (368) to hold the spacer plate and gaskets onto the control valve body (300).




8. Install the control valve body alignment sleeve (410) into the case cover (400).

Important:
* Use the control valve body alignment sleeve (410) and turbine shaft sleeve in the case cover (400) as guides.

* Be sure that the ball check valves do not drop out of the control valve body (300) during assembly.

Install the control valve body (300) onto the case cover (400).




9. Install the transmission fluid pressure (TFP) manual valve position switch assembly (395) onto the control valve body (300).

Important: Finger start the bolts to prevent cross-threading.




10. Install the control valve body bolts (374-381, 384) as indicated.

Notice: Refer to Fastener Notice.

Important:
* Tighten the bolts in a spiral pattern starting with the bolts at the center of the control valve body.

* If the bolts are tightened at random, valve bores may become distorted and inhibit proper valve operation.

Tighten the control valve body bolts (374-381, 384) as indicated by the following list.

* The 374 to 12 N.m (106 lb in)
* The 375 to 12 N.m (106 lb in)
* The 376 to 12 N.m (106 lb in)
* The 377 to 12 N.m (106 lb in)
* The 378 to 12 N.m (106 lb in)
* The 379 to 16 N.m (11 lb ft)
* The 380 to 25 N.m (18 lb ft)
* The 381 to 8 N.m (70 lb in)
* The 384 to 12 N.m (106 lb in)

11. Install the oil pump.




12. Install the wiring harness.
13. Install the case side cover.
14. Fill the transaxle to the proper level. Refer to Fluid Capacity Specifications.
15. Inspect the transaxle fluid level.
16. Inspect for fluid leaks.

Important: It is recommended that transmission adaptive pressure (TAP) information be reset.

Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, The ECM, PCM or TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.

17. Reset the TAP values. Refer to Transmission Adaptive Functions.
