Reverse Inhibit: Notes
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
If vehicle speed becomes greater than 12 km/h (7 mph) while the transmission is operating in REVERSE, the TCM commands the following changes to the transmission's hydraulic and electrical systems in order to inhibit reverse operation and prevent damage to the transmission.
