I bought this 96 Rodeo LS, Auto 4X4 about 1 year ago for $500.
Got it for the Price because of No reverse, I have done nothing to find/solve the problem.

All drive/park gear/s work good. All Indicator lights work, 4x4 works.

When I place shifter in "Reverse" I can feel it Engage, and if I'm on a Super Flat spot, it will roll about 3" in reverse, and I "Think" in Neutral.

Lady I bought it from had Motor Replaced about 10k miles ago, and said F it after it stopped going in Reverse. 140k'ish

I Know Motors, I dont know Trannys, "thought" it might be Tork Converter?
Does it sound like a Sensor (from what I seen about other trans issues) or the Tranny shot?
