WARNING: This page is about a different car, the 2010 GMC Sierra, 2010 GMC Cab & Chassis Sierra, 2010 Chevrolet Silverado, and 2010 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
Static Testing
- Ignition OFF, remove the TCC solenoid from the valve body. Refer to Control Valve Solenoid Replacement (SS1, SS2, SS3, TCC, and MAIN MOD) or Control Valve Solenoid Replacement (PCS1 and PCS2) .
- Test for an open circuit between the control circuit terminal 2 and TCC solenoid metal case and between the B+ circuit terminal 1 and TCC solenoid metal case.
- If not within the specified range, replace the TCC solenoid.
- Test for resistance between the control circuit terminal 2 and the B+ circuit terminal 1 of the TCC solenoid. Refer to Temperature Versus Resistance (Transmission Fluid Temperature Sensor)
or Temperature Versus Resistance (Speed Sensor)
or Temperature Versus Resistance (Solenoid)
.
- If not within the specified range, replace the TCC solenoid.
NOTE:
You must perform the Circuit/System Testing first.
