From what I have always heard about 86 and older trannies, is 100,000 miles, rebuild, repeat. Not sure about 87-up trannies...from what I hear they're stronger...anyways, no more rambling from me...ttt

the casing I thought was diff on the newers is all, THAT and teh number of splines on the imput. got a 700r4 for our 85 camaro and the tranny guy slipped up and gave us the bigger shafter verter with teh small imput.. we told him the sound when we took it to him, he checked it instantly, appoligized completely(we'd had the tranny and verter sitting for about 6 months before install with only 3 month warrenty) he tool care of it even checked out tranny to make sure nothign happened free of charge. hes our new drag tranny guy!

Rebuild it and upgrade the internals to at least 1987-spec...149k out of a 700R4 is good, really good...but especially if you're dropping it into something else other than the minivan again, I bet you'll be pulling it again to rebuild later if you don't do it now.

I'll let you know. 149,084 right now and pull a trailer and Bobcat once in a while.

1989 Astro van. The transmission has 396,000 miles and has never been worked on. The fuild has only been changed 3 times. Still going, but did start slipping about 10,000 miles ago. But it only slips when you are on it hard.

the camaro had an old 700 wiht 180K on it and it ran good, but we put a built 700 in, corvette syrvo and shift kit and all..

You should rebuild the trans. 6cyl and 8cyl trans are different from what i was told. They have less clutches and steels = less holding power. Just tell the shop its going behind a v8 and you want to tow with it, and they should be able to hook you up.

Its not worth it to do all that work to put the tranny only to have it fail on you when you are 20 miles out of town. Get it rebuilt while its out and convienent
