SERVICE PROCEDURE:
1.
Attach a GDS and select DTC Analysis and A/T menu. Record the DTC and description.
Delete the DTC.
2.
From the GDS home screen, select Data Analysis and A/T menu and the solenoid parameters
shown below. If the solenoids show:
 Continuous and changing output while driving, the wiring currently has no open/short
circuits. Go to Step 4.
 No continuous and changing output, go to Step 3.

3.
Visually check the wiring harness between the TCM and transmission for a damaged wire or
connector. Check for an open/short circuit.
 If so, repair or replace the ECM control harness and drive the vehicle to confirm the repair.
 If no damage is found, go to Step 4.
4.
Record the audio preset stations and disconnect the negative battery terminal.
5.
Locate the harness connector on the passenger
side of the transmission.
Press the tab in the center of the latch and push
the latch upward.
Push the connector up to disconnect the
connector from the valve body.
To gain better access to the connector, place a
support under the rear transmission support,
loosen the bolts about ½ inch and lower the
support about ½ inch.
6.
Use an 8mm or 5/16” hex wrench and remove
the fill plug.

8.
Remove 10 bolts that secure the valve body to
the case and remove the valve body.
Note the location of the 3 black bolts (shown with
black arrow).
If the valve body is stuck in the transmission,
insert a screwdriver between the valve body and
case and carefully pull the valve body out of the
transmission.
9.
Remove 9 bolts and remove the E-module.
