    Hi all I have a serious issue with a 94 1500 that we bought. When we got it the transmission was pouring fluid out the front seal so i removed the a518/46rh tranny ans replaced the pump and converter (before rebuilding) and all it had was forward gear. I've since rebuilt the entire unit and followed the instructions and specs from the ASTG overhaul manual. Well here's where I've run into my problem after reassebling the truck I put it on jack stands and have all the forward gears but no reverse. As long as it idles the rear tires will turn but as soon as you give it any throttle the tranny locks up like it has a drag racing transbrake in it. (Like reverse and a forward pack are engauging at the same time). Does anyone have any idea as to what can cause this, I've already removed the transfercase and od unit and and checked them out but i'm stumped as to what can cause this. Any Ideas or any help would be greatly appreciated cause between this thing and my wife driving me crazy about getting her truck fixed is driving me nutz.

    Oh yea I used a Transtar rebuild kit the had all new seals, bushings, borgwarner friction plates and band to rebuild thins thing. if any of that helps.

    did you soak the clutches before you assembled the trans?

    yes I soaked the friction disks and bands for about 20-30 mins before starting reassembly, just like I do with any transmission I rebuild

    is it possible that you have a fluid pressure problem? maybe the valve body is damaged? does the band hold in reverse or first, i can't remember, not familiar with dodge.

    Pressure tests.
    Might be that O`riellys has a trans pressure test system that they will rent to You.
    Hook the gauges to the pressure ports and please report back.
    Sounds to Me though as there could possibly be two clutches engaging at the same time.
    If there is only one pressure gauge in the kit then, rent another kit from somewhere, or put together the hoses and gauges.
    I think that there are three pressure ports.
