I have a 1990 4x4 k1500, transmission was a 4l60 before I lost 3rd and OD. I put a replacement 1987 700r4 in and it wouldn't shift out of first. I swapped/replaced governer, valve bodies, tv cable, tv valve, fluid, filter, even checked the wiring but none of it solved the problem. From this point I just want to start over and put a different transmission in. I'm 17 and on a low budget so rebuilt tranny's are out of my reach for now, I know a guy who has a 1985 4x4 700r4 and another guy has one out of an '86 burb.

SOOO main question, will the older 700r4's work with the '90 truck. I am aware that the 1984 and below 700's are one's to stay away from. Also, as far as I know the lockup control should work the same since the 4l60's below '93 were electronically controlled. Any information (faster the better) would be appreciated. Thaanks.
