A904 problem

if the linkage is out of adjustment so that the shifter doesn't quite get the trans in Park (shift leaver can't go any further) it will act that way.

I once was a passenger in a car that was misadjusted the other way. After driving for 200 miles at 65 mph, the driver said he thought that there was a problem with the car, that is seemed to be geared really low (high numerically). I reached over and put the shifter in the neutral location and the car lept forward as it shifted into third gear...
