In the event of an electrical failure, the vehicle can be shifted out of PARK by using the following procedure.
Using a flat blade tool, carefully pop it out of place.
Yeah, didn't think the over-ride would work. This was a HUGE problem for MANY Dodge/Chrysler vehicles. Yes- perfectly safe to tow. Bring it to the Dealer, and have them rebuild the shifter assembly. It's Recall #K39.
