Im going to wrap up this project finally. Got the last minute parts I needed yesterday and got the rig back on the road. Got about 10 miles on it so far, and so far, good. No passive or active engine oil leaks. Oil pressure is now showing correct and trans feels good.
I sourced my reman from Atransmissions.com. They were not the cheapest and not the most expensive. For my application, there was not a core charge. So I did not have to mess with getting it ready to ship back, and then wait for credit back to my card. Just had to be patient for it to get built and shipped. Took about 12 days from time of order, to arrive. Not a huge deal, as im in my slow time of year and have other wheels to get around.
I will likely gut the unit and separate the steel from the aluminum and haul to the scrap yard for its weight.
