With the engine up and running strong, I went to work on the rest of the drivetrain. Since it was a beach Jeep, I expected to find water in every gearbox. The T-case and tranny didn't disappoint as evidenced by this mocha milkshake draining from them. At least there weren't any metal fragments. The tranny and T-case were good to go after a flush and refill with fresh 80W-90 gear oil.
