Valve Body: Service and Repair

Control Valve Body Replacement

Removal Procedure




1. Remove the transmission side cover. Refer to Case Side Cover Replacement.
2. Remove the bolts (9, 12 and 16) from the control valve body assembly (18).
3. Remove the control valve body assembly (18).
4. Remove and discard the valve body to spacer plate gasket (22).

Installation Procedure




1. Install the control valve body to spacer plate gasket (22) onto the spacer plate (23).
2. Install the control valve body assembly (18) onto the gasket (22).




3. Inspect the transmission fluid pressure (TFP) switch assembly (13) in order to verify the condition and correct location of the 4 pressure switch O-rings.
4. If necessary replace the pressure switch O-rings.




5. Install the TFP switch assembly (13) onto the control valve body assembly.

Notice: Refer to Fastener Notice.

7. Hand start the bolts.

Tighten the bolts to 14 N.m (124 lb in).

8. Install the transmission side cover. Refer to Case Side Cover Replacement.

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.

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