I also pulled the pan on what I assume is the original TH350 from my 70 S. Very little crap inside, has a converter drain and a dual bell housing bolt pattern.
I could ask the wrecker, my wife picked it up for me. I am betting it is from a big car. I was surprised to see what should be the original trans from the 70 being dual pattern and not filled full of sludge.
Of course, this one has a brown gear vs the black, will be slightly off with the green 10 tooth gear.The fluid is a bit dirty but not burnt. No sure if the wrecker cleaned the pan, if not, it is very clean inside. I am stealing the lock up kit, Hughes pan/4L60E filter, mount from the other trans, should be done tonight. I did both front and rear seals as well. No fancy ATF, just Dexron 3.
According to the TurboBuick site; an '84 HE is Caprice, DeVille, Impala, LeSaber, and Parisienne w/ V-8 305" 5.0L Canada. In '87 the trans code changed to HF for the same models. Hope that helps!

That sounds right, hoping it shifts through the gears like it should.
