    I don't use any additives. Try a bigger trans cooler or a lower temp thermostat maybe even an oil cooler would help

    Red line makes a good one, I think its called water wetter? It's red in color. I used it a few times and it works good.

    It might drop the temp a few degrees, best would be to use an oil cooler if your truck doesn't have one. Not a bad idea if you tow a lot.
