Ive done a lot of tranny rebuilds and have broken a few tranny's over the years, but this one is a bit wierd. I was in Moab wheeling the new rig. It worked great. I finished wheeling for the day and drove about 5 miles in 2wd on the highway, then came to a complete stop. Up to this point everything had worked flawlessly. I got on another highway and accellerated hard and held down the gas pedal. Everything seemed fine but it didn't shift up. I let off of the gas for a second to promote a shift up and the tranny went into freewheel. There were absolutely no bumps, grinds, jerks or noises when this happened.
I have no forward or reverse gears. The tranny will hold the vehicle when in park, so the tcase is not the problem. After pulling it back to the campground, I pulled the tranny cooler line and put it in a gallon jug. I started the engine for about three seconds and ended up with a half quart of fluid in the jug, as I hoped. Just for grins, we pulled the inspection plate and the TC bolts were all fine, as expected from the above test. There were no leaks.
I pulled the pan, there was absolutely no debris in the pan. It was clean. I went ahead and replaced the filter with a new one and buttoned it back up and replaced the fluid. Still nothing. I pulled the tranny computer connector, still nothing. So I said screw it and pulled it home.
My best guess is that I have a piece of something causing a valve or solenoid to stick in the valve body.
Has anybody else seen this? If so what was your solution?
Anybody know where to get a gauge to measure the pump pressure on an AW-4?
