    We run Swepco hydraulic transmission fluid in the trophy truck, and I run it in my boat as well. It handles heat better than anything else. All last week at the Norra off-road race we were continually seeing 280 temps on the trans, and the oil is still bright red.

    Just food for thought but the torque converter is where most of the heat is produced in an automatic transmission. Since there are no torque converters in our boats, they do not see the same temps as a wheeled vehicle. Coolers are nice but essentially overkill in a boat (I run one anyway though). I run Valvoline Max Life Full Synthetic in my TH400. It always comes back out red.
