Action Taken When the DTC Sets

WARNING: This page is about a different variant/trim than selected.

Powertrain braking is disabled at the time that the TCM first detects the failure, before the DTC sets.
The TCM requests the ECM to illuminate the malfunction indicator lamp (MIL) during the second consecutive drive trip in which the Conditions for Setting the DTC are met.
The TCM turns off power to all solenoids.
The transmission will operate in fifth gear if the vehicle has successfully completed a 1-2 upshift in the current ignition cycle. If the vehicle has not completed a 1-2 upshift in the current ignition cycle, the transmission will operate in fourth gear. If the transmission is operating in fifth gear, fourth gear may be obtained if the engine is stopped briefly and started again.
The TCC commands maximum line pressure.
The TCM freezes transmission adaptive functions.
Torque management is inhibited.
At the time of the first failure, the TCM records the operating conditions when the Conditions for Setting the DTC are met. The TCM stores this information as a Failure Record.
At the time of the second failure, the ECM records the operating conditions when the Conditions for Setting the DTC are met. The ECM stores this information as a Freeze Frame.
The TCM stores DTC P0973 in TCM history.
