TCC Solenoid, TCC PWM Solenoid & Wiring Harness: Installation
WARNING: This page is about a different car, the 2003 Chevrolet Corvette. 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. Install the valve body bolts which retain the internal wiring harness and install the TCC solenoid retaining bolts. Tighten the control valve body retaining bolts to specification. See TORQUE SPECIFICATIONS . Tighten the TCC solenoid retaining bolts to specification.
- Install the pressure control solenoid. Ensure that the electrical tabs are facing outboard. Install the pressure control solenoid retainer and retaining bolt. See Figure . Tighten the pressure control solenoid retaining bolt to specification. See TORQUE SPECIFICATIONS . Install the TCC PWM solenoid to the control valve body. Install the TCC PWM solenoid retainer. See Figure .
- Connect the internal wiring harness electrical connectors to the following components: 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. See Figure . Install the 1-2 accumulator. See ACCUMULATOR ASSEMBLY, SPACER PLATE & GASKETS .
- 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 the transmission to the proper level with appropriate fluid. See LUBRICATION .
