Good news! My transmission is in and works like a dream. Mickey’s crack team of mechanics got the transmission installed in good order. They had a few bumps from the ancient original hoses that were still in use. The ones that gave the most trouble were replaced by Rover Cannibal.
I knew going in that the transmission fluid cooling hoses needed to be swapped out. Instead of swapping, Mickey sent them to Palace Auto Supply for them to be re-made. The oil cooling hoses, as I’ve mentioned before, were “wet” and needed to be replaced before they facilitated a lovely engine fire.
