700r4 won't downshift- never has

I have a 700r4 out of an 87 chevy 6.2 diesal van installed on my 72 chevy c10 350ci. The trans worked fine in the van but it slips on heavy acceleration between shifts and will never downshift even at WOT. Its done this since i put the trans in and the previous 700r4 i had in it did the same. Something isn't adjusted right and maybe i ruined it already. Any ideas? I adjusted the TV to every position imaginable, and i fixed the bell crank for the right geometry according to GM specs. I'm using the torque converter that came with the old trans... the one that quit. the diesal one was different. Is the trans built for the diesal and need like a different valve body for my 350 maybe? What do u think?
