I have a 94 dodge van b-150 ram this nightmare I just bought it wouldn't move. Did tran fluid, filter still slipping noticed it wasn't charging so put a alternate on it ran, shifts fine, great for 2 --10 mile trips in town then parked it next day after snow I tried to move it when I put it in all gears it howled and would move 1 foot to 1 block then all gears would go to neutral the howl goes away but then it wont move en tell I reset the computer by pull off + line. Then tran will engage for a min. Or second an howl en-tell all gears gone. Am I missing a wire to tran or what? Does cpu control shift modulator I see no vacuum modular on tran is this electric?Why with no warning just like when I bought it I did drive it fine something is mad again is there any way the tran filter fell into the pan what would this do as the symptoms?
i have no check eng. Light and the moter runs great?

what kind of tran is this 1-2-D-N-R-P
no overdrive button or gear. Does it have a electric lock torque converter could this be it?
does the censer on the rear end for ABS have anything to do with the tran?
please help!

thanks matt!

Sounds like you're confusing this really tough transmission for a GM model. Chrysler never used a trouble-prone vacuum modulator valve for shifting. That is done with a very simple, reliable linkage from the throttle body. The sensor at the rear of the transmission is the vehicle speed sensor (VSS). If you have rear-wheel-anti-lock brakes, the speed sensor for that is in the top of the rear axle. The lockup torque converter was invented by Chrysler and first used in 1977. It was completely hydraulically-controlled. Yours will be electrically-controlled by the Engine Computer. Unless there is something I'm not aware of, you should have an overdrive unit added to the tail housing of the transmission and there should be a square button to the left of the steering column to turn it off. There should be a circle around the "D" on the shift indicator if I'm right. The filter can't fall off as in some other manufacturer's designs because it is held on with three screws.

If you look at the transmission pan and it is basically a rectangle with the right front corner shaved off, that is based on the old 904 model. It is being used more because it is lighter weight. Trucks and vans usually had the tough and reliable 727. The pan for that one has an extra "bump-out" on the right front corner. (The 904 pan is missing a part of the rectangle; the 727 has more than a full rectangle). Both models use the same valve body but the clutch packs are larger in the 727. Neither one is computer-controlled in '94.

When it is slipping as you described, the place to start would be with pressure tests performed by a mechanic. Those will help isolate the cause of the problem.
