Stop in for a cup of coffee

What's the scoop? A later model extension and filter on a early transmission? Does it have to do with the rear pump?
Looks like it. A LOT of builders think they can just block off the fluid to the rear pump and that it’ll be fine. It doesn’t work out 99.999999 times out of 100. Eventually it eats that rear pump and sends metal through the entire thing, destroying the rest
