What could cause a 1992 Plymouth Voyager with 190000 miles and a rebuilt transmission to stall when put in gear?

Answer 1

I've had my '97 Plymouth Voyager stall going into gear (from park) when the Transmission Fluid was really low (down more than a quart). I've also had that same van stall when an O-ring in the distributer got bungled up, presumably from spraying the engine with a pressurized hose. Oops :)

The distributor problem was very hard to diagnose.
