|What Does the P0842 Pontiac Code Mean?

The Torque Converter Clutch (TCC) release switch is part of the automatic Transmission Fluid Pressure (TFP) manual valve position switch. The TFP manual valve position switch is mounted to the transmission valve body. The TCC release switch is a normally-closed switch.
When the TCC is released, TCC release fluid pressure opens the TCC release switch which opens the TCC release pressure circuit. When the voltage on the circuit is high (switch open), the Powertrain Control Module (PCM) recognizes that the TCC is no longer engaged.
