Mag-Hytec
I plan on installing one with the first fluid and filter change. On my 1996 I went from petro to synthetic and saw a 30 to 50 degree drop, pulling my 33' 5th whl. I would run 140 degrees in the pan. I know that our trucks are now running synthetic, this will help with the heat, but I like the cooling fins and the extra fluid with the DD pan so I will probably opt for it. I also used the "A" fluids and believe in them. I am going to use one of the test ports until the F/F change. I believe that you measure your Transmission temperature in the pan, so I plan to add the Maghytec pan with the ports for the temp. probe and a drain plug.
