Newer 700R4 behind diesel

87 R10, 6.2 diesel, 700r4. Truck sits a lot, I drive it a few miles every month to keep the batteries up and make sure most all of it works.
The trans develeped an occasional cycing TCC, appeard to b only hot in the summer, under loads like going up moderate hills. Recently it has delayed engagement on cold starts. I also noticed grass kill under it, thought it was the filter but now I think it's the trans leaking out the bell housing area.

Being a moderately rusty 2wd diesel the truck is probably worth $1500 runnning. With a bad trans, it's a $500 parts machine. Getting the trans rebuilt is about $1400, about $900 if I do the in-and-out, and most of the hard parts on my 200,000+ mile trans are good.

Happened to be browsing and found a rebuilt unit for $500. No converter. Looking at it it has the rainbow and no pressure taps so I'm thinking its a later unit, and no K case so 2wd. It's been sitting on the shelf for a bit, it looks dusty but does not appear to have been installed since the rebuild. Looks like it might be the thing to get the beast up and going again.

I know the governer will need to be swapped, and the TCC rewired. I would buy and install a low stall converter, and my speedo gears. Any other think I'm missing?

Other options are convert to long shaft TH350 (about $500 for ready to go unit), a-833 (about $150 for parts but a bunch of time I don't have), or just broom the beast cheap.

1987 C10 6.2 oil burner

Dad's 1981 3/4 L6 3 on tree posi and no options, awaiting restoration or scrapping
