Tranmission Slips into Neutral when i come to a Stop

[martygunn]

I have a 1992 Grand Prix that goes into Neutral every time I come to a stop. It's not physically moving the shifter, but if I move the shifter to Neutral and then back into OD the gear engages again.

The Transmission shop says it has to be electrical, but I know if I take it into them they are going to want to rebuild it, regardless of the problem. You guys have any suggestions?

if you keep it out of overdrive and in just normal drive, does it still do it?

[martygunn]

No it does not. Just in OD.

all i can gather, is try a complete transmission fluid flush. i was reading on here, and someone recommends seafoam transmission treatment. but my thoughts is that the overdrive gear is going bad.

you have a sticky shift solenoid. Trans-X or Seafoam may help, but more than likely you need a mechanical fix, ie replace the faulty solenoid.
