Ram tranny problems

It didn't look too bad. There was some stuff there but I don't think it was excessive. No big chunks. I'm just getting frustrated. 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. Why? If its not broke don't fix it. Nothing else slips it shifts when it should (except first of course). I can't even find a tranny around here, only 5 speeds, and if I do find one I bet I won't touch it for a grand. I can get a 5 speed trans for 400 and the pedals shifter hydraulics and computer for not much more at a u-pull it. Just get the vin flashed to the new computer and go. Sorry I'm just venting. I just don't know what direction to go. I keep second guessing everything.
