Pre 87 700r's are not a good trans.7 vane pump instead of ten vane etc. When I was looking for one I had a free 85 700r. I got a kit from B-M to rebuild it and found that they wanted me to replace all kinds of parts with post 87 parts. So I called them and they said this was not even possible.....I had already pulled this thing apart and could see what they meant. So I returned the kit and went to the junk yard checking #'s. Found one in a pile that the guy said was cores. Bought one for $50. Put the new completely different B-M kit in it with Corvette servos and yadda. Drove from Cali to Florida no prob. Then boom. TCI torque converter blew up. Had it cut open and wouldn't you know it..Totally stock unit ???? Had one custom built and replaced the pump. Ground pounding wheel spinning 4wd monster!!! Thank you Tampa Converter! Moral = free sometimes is not good AND no more expensive TCI converters!
