"Last week after driving the car for an hour or so it would not shift out of reverse."

AND
"I turned the key to start and it started in reverse"

First quote indicates the pressure sw. is hanging open after having driven the car enuf to build pressure.

The second quote indicates the pressure sw. is hanging closed.
i.e. the pressure sw. mite be hanging up either open or closed and doing it sporaticly.

Of course there could be wireing problems as BH indicates or even relay problems beyond the pressure sw.. The pressure sw. is ez enuf to bypass and to eleminate from the system for diagnosing the rest of the more complex system.


Try this before u do anything:

Select "N" always before selecting ANY other button. Select the buttons slowly. See if that solves the problem.
