    That's a question best asked at a salvage yard or transmission shop.  However, you probably don't need a new transmission.  Before spending a bunch of money on the deal, try changing the fluid and filter.  Don't go to a Jiffy-Crap and let them use one of those pumps.  Get on your back and slide under the truck (there is loads of room).  Remove the pan and catch the old fluid.  Replace the filter and refill with fresh fluid.  Dodges are famous for going south when the filter gets dirty, and losing reverse is always the first symptom.  This will be cheap to do, only take a little while, and will cure your problem.  And, whatever else you do, DO NOT use sealer on the gasket (it must be installed dry).
