Shift Actuator

As a first step in servicing the Shift Interlock Solenoid one must disable the SIR system. First remove the knee bolster while positioning the shift lever assembly to its neutral clevis position. A small screwdriver helps to detach the automatic transmission shift lock control actuator from both the steering column jacket as well as the cable shift cam after disconnecting the electrical connector. Fitting the shift lock control actuator requires first attaching it firmly between the steering column jacket and cable shift cam followed by electrical connector reconnection. To adjust the shift lock control actuator with the shift lever clevis in neutral position users should do the following: pull out the tab on the adjuster block side and press the adjuster block to compress the internal adjuster spring then detach the adjuster teeth and finally slide the adjuster block away from the actuator as much as possible before locking it with the tab. The shift lock control actuator must operate correctly as it maintains the shift clevis in park position but releases the park lock when the brake pedal activates. The device needs to receive electric power. You should readjust the shift lock control actuator when needed before placing back the knee bolster and activating the SIR system.

Service procedures for the repair of 4l60-e/4l65-e/4l70-e automatic transmission solenoids should start with transmission filter extraction. Service of the pressure control solenoid requires the 1-2 accumulator to be taken off as well. Disconnect the internal wiring harness electrical connectors from the transmission fluid pressure switch as well as the 1-2 shift control solenoid , 2-3 shift control solenoid , pressure control solenoid , torque converter clutch pulse width modulation (TCC PWM) solenoid , and 3-2 control solenoid . To access the pressure control solenoid the technician must first take off retainer bolt (364A) and retainer (378). Afterward they can remove the pressure control solenoid (377). Start by separating the 1-2 Shift Solenoid retainer (395) along with the 1-2 Shift Solenoid (367A) component followed by removing the 2-3 Shift Solenoid retainer (395) combined with the 2-3 Shift Solenoid (367A) element and completing with separation of the 3-2 control solenoid retainer (395) and the 3-2 control solenoid (394). Install the 3-2 control solenoid (394) and its retainer (395) before positioning the 2-3 Shift Solenoid (367A) together with its retainer (395) followed by the 1-2 Shift Solenoid (367A) and its retainer (395). Install solenoids so that their electrical connectors point towards the non-machined (cast) side of the Valve Body to avoid transmission case interference. During pressure control solenoid (377) installation place the electrical connector into position 1. Use the pressure control solenoid retainer (378) which requires tightening its retainer bolt (364A) to 11 n.m (97 lb in). The internal wiring harness electricity must be joined again to the transmission fluid pressure switch , 1-2 shift control solenoid , 2-3 shift control solenoid , pressure control solenoid , tcc pwm solenoid , and 3-2 control solenoid . The 1-2 accumulator requires replacement along with the transmission filter if needed. Transmission adaptive pressure (TAP) values require reset by a scan tool because this action removes all learned values stored in cells yet Engine Control Module (ECM), powertrain control module (PCM), or transmission control module (TCM) need to relearn tap values which impacts transmission performance throughout this procedure.

The maintenance process for control and shift solenoids starts with removing the transmission oil pan along with its filter. The removal of the Valve Body is only necessary for pressure control solenoid maintenance that requires taking out the 1-2 accumulator. You must disconnect all internal wiring harness electrical connectors from electrical components 1 through 6. First disconnect the pressure control solenoid (377) while keeping track of its original position and then take off the solenoid retainer (378) followed by the solenoid retainer bolt (364A). Next, you should take off both the Shift Solenoid retainers along with the actual solenoids from the 1-2 and 2-3 positions. Set the electrical connector side of all solenoids to face against the non-machined (cast) side of the Valve Body to avoid potential transmission case binding during installation. Follow the 1-2 and 2-3 Shift Solenoid (377) and retainer installation by adding the actuator feed limit valve (374) and spring (375), bore plug (376) along with retainer (395) and pressure control solenoid (377) to the unit. Secure the retaining bolt at 11 nm (97 lb in). Reinstall the 1-2 accumulator after reconnecting all internal wiring harness electrical connectors that control electrical components (1-6). Place the transmission oil pan while also installing its filter before adding dexron(R) vi transmission fluid to the fluid level specification. A scan tool must be used to reset transmission adaptive pressure (TAP) values which will remove all learned values before Engine Control Module (ECM) or powertrain control module (PCM) or transmission control module (TCM) learning process begins because resetting tap values influence transmission performance.

To properly install the pressure control solenoid (377) position its electrical connector into position 1. Install the pressure control solenoid retainer (378) before attaching the retainer bolt (364A) while tightening it to 11 n.m (97 lb in). Reinstall the transmission internal wiring harness electrical connectors to the mentioned devices including the transmission fluid pressure switch , 1-2 shift control solenoid , 2-3 shift control solenoid , pressure control solenoid , tcc pwm solenoid , and 3-2 control solenoid . Reinstall the 1-2 accumulator together with the transmission filter in case of need.
