We have a 1986 Chevy Suburban with a ZZ4 350 in it. We stopped using the truck years ago, but we never had a problem with it. but was still ran and drove around a little bit. Just recently we started it back up after sitting for a couple weeks, and it wouldn't move. It only moves it you rev it to about 4 grand, and it still it very faint. The dipstick reads full for the tranny. I think it might be a pump, or possible clogged tranny filter? BTW Motor has 60,000 on it, but truck has 280,000 lol Good ole Chevy's

Front pump of tranny can keep up pressure. Whole rebuild is best but you can do just the pump. Probably a turbo 350 trans and they don't last long after 200k usually even with good care. 700R tranny was good too but same thing - that's a lot of miles on it,
