No one will touch that tranny for less than 1200 bucks.
They claim that valve body, converter, clutches, and all the electronics need replaced if its opened up.
The truck has 158,***. Motor is strong and no cancer holes. There is a little rust on the pass side rocker but maybe the size of a quarter and still solid(tried pushing my finger through it). I got it cheap and I figured it would need a little work. I think I'm going to try it myself that's how I learned how to do everything else. Thanks guys for all the help and hopefully within the next few weeks I will have a good truck worthy of pulling the dart around. There's no way I'm pulling the dart with a chevy or ford.
Well I've been sitting on what to do and what the possible problems are and after a month I stumbled on something that I wanted. I found a complete set up to make my truck a 5 speed with a nv4500. It came with everything computer pedals bell housing trans slave and master cylinder. I paid 650 for everything. I will probably be one of the only people running a 5.9L 1500 with a nv4500. The swap is coming this week I can't wait. Thanks to everyone for the advice.
