If we're talking 1/2 ton, yep. It would have been the 700r4. They did produce big block 3/4 ton trucks with the 4L80E, first year for those though.
I believe they were making the SS454 truck back then, which would have come with a TH400 3 speed.
That's off the top of my head, and I'm an old guy! Did you check it out on Wikipedia?

without jacking the thread, I just picked up a 1990 GMC 2wd 5.7, the overdrive is out of the trans, I lucked out and found an older 78-87 style 2wd 350, the only thing I have to go off of is the '90 had 1,2, & OD.. and the older truck had 1,2 & D... this is just going off the dash indicator, have not crawled under and looked or anything, he said it would fit and it worked so I said sold, now what have I bought? would this most likely be a th-350/400 or is it just a 700R4 without OD? newbie so just asking I looked in wiki, but figured I'd check here
