The above described Vehicle has a 3.0 V-6 engine. The Automatic Transmission is a 4R44E. If I hit a "bump" in the Road, the engine would temporarily "die" and immediately come back to life.
I have changed the Shift Position Sensor and the Speedometer Sensor on the Side of the Transmission. I also took the Pan off the Transmission and checked for loose connections going to the Servos. The Connections to the Transmission was also observed for Loose Connections and Burnt Wiring. Nothing seems to help. A local Garage placed a "hand held" Analyser on the Truck. Some kind of "open circuit" was shown. Can the Computer be analysed?
I was "forced" to take a temporary route to my home. The Road was a "washboard" and rough. The Overdrive Light would repeatedly come on and off. Finally, the Truck refused to pull or shift gears. The Engine ran extremely rough and would not run faster than an idle.
