I got back from a 200 mile trip. Parked the van in the drive way and proceeded to unload the gear. Got back in the van approximately 30 minutes later and drove the van into the garage. Attempted to put the van into Park but it would not shift past Reverse. I was sucessfully turned the car off and let it sit for awhile. Started the car back up and was able to shift into all gears except Park. Ever since the car will not start and the gear shifter moves freely from gear to gear. Any suggestions ?
