Larger transmission cooler

[wildwoodrver]

My '05 Yukon XL pulls my 30 foot Airstream very well. No complaints at all. On very hot days going up long pulls the water temp gets close to "too high" and we just open the windows and turn on the heater. Never fails.
But...there is no easy fix on the transmission heating up.
My fix would be to add another oil cooler or replace the OEM with a larger unit.
Anyone done this? Appreciate your feedback.
Thanks.

Absolutly tens of thousands of people have done this.
Basic rule of thinking is this..


If you can think of it, 500 people have thought about it already and 100 have done it.

Here is what you seek to solve your high trans temps.

Replace the stock unit with the Tru Cool 40K unit. You can use your stock lines as well.

Get the biggest trans cooler you can fit up front and ditch the OEM one, you will be much happier!
