TCC Solenoid, TCC PWM Solenoid & Wiring Harness: Installation
WARNING: This page is about a different car, the 2003 GMC Savana and 2003 Chevrolet Chevy Express. However, it is still accessible from the selected car via links, so may be relevant.
- Install the wiring harness and TCC solenoid assembly with a new "O" ring seal to the transmission. Install the pass-through electrical connector to the transmission case. See Figure .
- Install the valve body bolts which retain the internal wiring harness and install the TCC solenoid retaining bolts. See Figure . Tighten the control valve body retaining bolts to specification. See TORQUE SPECIFICATIONS .
- Tighten the TCC solenoid retaining bolts to specification. See TORQUE SPECIFICATIONS .
- Install the pressure control solenoid. See Figure . Ensure the electrical tabs are facing outboard. Install the pressure control solenoid retainer and retaining bolt. Tighten the pressure control solenoid retaining bolt to specification. See TORQUE SPECIFICATIONS .
- Install the TCC PWM solenoid to the control valve body. See Figure . Install the TCC PWM solenoid retainer.
- Connect the internal wiring harness electrical connectors 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 shift control solenoid. See Figure .
- Install the 1-2 accumulator. Connect the transmission harness 20-way connector to the transmission pass-through connector. Align the arrows on each half of the connector and insert straight down. See Figure .
- Install the transmission oil pan and filter. See DRAINING & REFILLING under LUBRICATION. Lower the vehicle. Fill transmission with appropriate fluid to proper level. See RECOMMENDED FLUIDS and FLUID CAPACITIES under LUBRICATION.
