Use the 'new' Dextron vi fluid - it is backward compatible, and will soon be the 'only' Dextron. Consider a friction modifier. I use Tufoil. I believe the main reason they are not 'recommended' is they would fail the emission, warmup test. When I used it the first time in a high mileage vehicle, I had to block the radiator to get enough heat from the heater, at cold temperatures.

The deep pan will not work as it only leaves about 1/4" clearance to the exhaust pipe that runs under the rear of the pan. Derale only makes a deep 4" pan for the 4L80L.
