* The TCM commands maximum line pressure.

* The TCM turns off all solenoids - HSD1 and HSD2.

* The TCM freezes transmission adaptive functions.

* The TCM defaults the transmission to third gear if the current gear is 1st, 2nd, or 3rd; or fifth gear if the current gear is 4th, 5th, or 6th gear.

* The TCM inhibits TCC.

* The TCM inhibits Tap up and Tap down functions.
