Same thing happened to us in our 340 car. If you are using a late 727 case, Chrysler didn't machine the groove in the front clutch drum (IIRC) correctly and the seal starts to leak where the up shift occurs later and later. An air test with the valve body removed will confirm this. If so, the trans has to come out. Replacing the seal will fix it for a while.

Sounds like worn governor sealing rings....they can be replaced without pulling the trans.

Your trouble isn't inside the pan; lift-throttled shifts to 3rd and uncommanded downshifts to 2nd are classic governor sealing problems.

Is it easy to change the seals? My wagon seems to be doing the same thing. Where are the seals available from?
Thanks
