Diagnostic Aids

When attempting to set transmission performance DTCs, observe the Freeze Frame and Failure Records to assist in duplicating the failure conditions. Ensure the transmission fluid level is correct and there are no leaks.
Under certain conditions where P0751 sets, the TCM provides functional status to other control modules. This may result in the module disabling the cruise control. For this condition, correct the DTC and then power-down to reset the TCM.
