Control Valve Body Replacement Automatic Transmission Unit Control Valve Body
Removal ProcedureRemove the fluid level indicator.Raise the vehicle. Refer toLifting and Jacking the Vehicle.Remove the oil pan, gasket, and filter. Refer toAutomatic Transmission Fluid and Filter Replacement.
Disconnect all the internal wiring harness electricalconnectors from the electricalconnectors-(1–6) components.
Remove the torque converter clutch (TCC) pulse widthmodulation (PWM) solenoid retainer-(2) with a smallscrewdriver. Rotate the solenoid-(1) in the bore, ifnecessary, until the flat part of the retainer-(2) isvisible.Remove the TCC PWM solenoid-(1) in order to accessthe TCC solenoid retaining bolts.
Remove the TCC solenoid retainingbolts-(68).
Remove the TCC solenoid (with O-ring seal) and wiringharness-(66) from the control valve body.Reposition the harness to the side of the transmissioncase.
Remove the manual detent spring bolt-(64) and thespring assembly-(63).Remove all valve body bolts.
Carefully begin to lower the control valve body down from thetransmission case while simultaneously disconnecting the manualvalve link.Installation Procedure
Install the checkballs-(1–7) in thevalve body.
Install the control valve body-(1) to thetransmission case while simultaneously connecting the manual valvelink to the manual valve.Verify that the manual valve link is installed properly tothe inside detent lever and the manual valve.
Install one bolt-(M6 X 1.0 X 47.5) hand tight inthe center-(1) of the valve body to hold it inplace.
Install the 12-valve body bolts-(62),2-bolts-(59) and3-bolts-(120) that are shown only.Finger tighten the bolts.
Install the transmission wiring harness on the valvebody.
Caution:Refer toFastener Caution.Install the TCC solenoid valve and bolts-(68).Tighten the bolts to8–14-Y(71–124-lb-in).
Caution:Do not over-tighten the bolts. Over-tightening the bolts willdistort the valve bores. Begin tightening from the center of thevalve body tighten the bolts in a outward direction.Inspect the ensure all of the valve body bolts are in thecorrect location. Each bolt number refers to a specific size, asindicated in the following list:59-M6 x 1.0 x 35.0 (Qty:-2)62-M6 x 1.0 x 47.5 (Qty:-12)120-M6 x 1.0 x 54.4 (Qty:-3)Tighten the bolts from the center of the valve body workingyour way out in a spiral pattern to the outside edge. Tighten thebolts to8–14-Y(71–124-lb-in).
Install the TCC PWM solenoid valve-(396) and thesolenoid retainer-(395).
Snap the wiring harness in place on the valve body bolts.Ensure the harness loom tab is located under the transmission fluidpressure (TFP) switch.Install the wiring connectors to the electricalcomponents-(1–6) as indicated in the followinglist:The manual shift detent lever with shaft position switchassemblyThe 1–2 shift solenoidThe 2–3 shift solenoidThe pressure control solenoid (PCS)The TCC PWM solenoidThe input speed sensor (ISS)Install the transmission oil pan and filter. Refer toAutomatic Transmission Fluid and Filter Replacement.Lower the vehicle.Fill the transmission to the proper level withDEXRON®-VI transmission fluid. Refer toTransmission Fluid Level and Condition Check.
Note:It is recommended that transmission adaptive pressure (TAP)information be reset.
Resetting the TAP values using a scan tool will erase alllearned values in all cells. As a result, the engine control module(ECM), powertrain control module (PCM) or transmission controlmodule (TCM) will need to relearn TAP values. Transmissionperformance may be affected as new TAP values are learned.Reset the TAP values. Refer toTransmission Adaptive Functions.
