It appears that the AC Delco kit comes with the rear case plugs. I didn't realize they were rubber clad. Only see one seal kit that has the valve body screen.

Got around to checking out the transmission today. It has the newer style output shaft. I suspect it is still on back-order even though a few places still show it as being in stock. There seems to be a good amount of friction material in the pan. No dirt or metal in the fluid. Fluid was a bit dark, and was probably in need of changing. Not sure of the service interval on these transmissions/vehicles, but it may have never been serviced.

Everything look good to you?
