thanks Art ,after interviewing people who tried to help before i got there i may be on to something.
problem started when wife left park lites on and run battery completely down.
someone forced shifter so they could move it and use jumpers on it .
this caused probe on right side of shifter to come out of slot it runs in ,after getting it back in all problems cleared up except not going to overdrive.
I thinking this may have already been a problem and she hadn't noticed the high revs.
I was thinking of ordering a bypass plate of of e-bay ,do you think I'm heading in the right direction ? last time i drove it this function worked fine
