I just replaced the transfercase and the overdrive unit in my 03 dodge ram 2500 diesel.....I got it all done no real hassel BUT I start the truck back up and its stuck in park what the heck is going on someone please help me out...Am i correct to assume that replacing the transfer case and over drive unit would have nothing to do with the fact I cant shift the truck???? And yes is did shift when I parked the truck in the garage to replace the listed parts.
