I checked for vacuum leaks and found none.I'm not sure what you mean by engine temperature sensor following the surge, but the car is reading normal on the temp gage.
Today I was driving home with the usual surging back and forth in drive and overdrive.
I made a stop on the way, left it running (in park).I got back in and started driving, once I reached 50mph I noticed it wasn't shifting into overdrive and the surge was gone so I accelerated to about 70mph still no shift or surge but when I would let off the gas it would drop to about 1000rpm's kind of like it was coasting in neutral, then when I hit the gas again the tranny wouldn't engage until 3000rpm's and I was doing 50mph.
This has happened a couple of times before, and if I shut the car off and start it back up the tranny shifts into overdrive and all my surging is back.
I'm completely stumped, as it seems to be electrical.I have looked through all the connections to the tranny. Any Ideas?
