Sanity Check: 15-Year-Sat 904 Swap Plan to Get Me to MoParty

Was it in a heated mostly dry shop? Should work fine really. Be surprised if it has a problem.

I rebuild a trans for a guy. He never installed it. 10-12 years passed. I bought it and used it as is, works fine, shift seal started seeping after a few years.

Your plans is good.
