Installation Procedure
- NOTE:
Inspect the 4 filter plate retaining tabs on the control solenoid valve assembly. A broken or missing tab may not adequately secure the filter plate to the control solenoid valve assembly.
Install a NEW filter plate assembly (1).
- NOTE:
Note the locator pin on the control valve lower body assembly.
Align the control solenoid valve assembly (1) to the control valve lower body assembly.
- Install the 2 bolts (2), through the "heat sink" side of the control solenoid valve assembly (1). Hand tighten only.
Install the 4 bolts (1) and 5 bolts (2) securing the control solenoid valve assembly to the control valve lower body assembly. Hand tighten only.
Install the manual shift shaft position switch assembly (1). Align the switch activator slide with the manual valve link. Secure with 1 bolt (3). Hand tighten only.
- Connect and lock the manual shift shaft position switch electrical connector (5) to the control solenoid valve assembly and attach the wiring harness clip (4).

CAUTION:
Bolt torque sequencing is critical to the proper function of the control solenoid valve assembly. Failure to follow the required sequencing may result in transmission malfunction.
CAUTION:Refer to Fastener Caution .
Tighten all bolts in the sequence shown. The 2 "heat sink" bolts (17, 18) must be tightened last.
Tighten bolts to 8 N.m (71 lb in).
Inspect the contact area between the "heat sink" area of the control solenoid valve assembly (1) and the valve body. There should be no visible gap. If a gap exists, loosen all 18 bolts and retighten in the sequence shown.
Inspect the 2 input and output speed sensor wiring harness clips (1) for damage. Replace if damaged.
Connect the speed sensor electrical connector (2) to the control solenoid valve assembly.
Install the upper and lower control valve body assembly (1). Control Valve Lower Body and Upper Body Replacement
- Install the electrical connector passage sleeve. Automatic Transmission Electrical Connector Passage Sleeve Replacement
Install the transmission oil pan (1) and filter. Automatic Transmission Fluid, Fluid Pan and/or Filter Replacement
- If a NEW TCM has been installed into the vehicle, the NEW module needs to be reprogrammed. Service Programming System (SPS)
- Perform the Reset Transmission Adapts. Reset Transmission Adapts
The wiring harness clip (4) on the manual shift shaft position switch does not need to be replaced if damaged or missing. The clip functions only as a manufacturing assembly aid to keep the harness clear during an automated bolt installation process. If the clip is damaged, simply remove and discard.
