If you are going to put a rebuilt one in it heres the brand I recommended buy one from jasper engines
www.jasperengines.com they have a 3yr 75,000 mile warranty that even covers the labor cost to install a replacement. My dads dodge ate throught 5 transmissions (mopar ones and other reman ones) and this is the first tranny that we haven't had a single slightest bit of problems with. Plus they call you a couple times a year to ask hows your vehicles (which is really kind of them in my opinion). I also have an engine from them in my cadillac and that engine is notorious for shitting out awfully quick. I haven't had the slightest problem with it either.
