    DefaultTundra Transmission cooler

    Any thoughts on the factory installed transmission cooler on the 06 Tundra Double Cab 4.7L
    Is it adequate for pulling a travel trailer at max towing weight. The book indicates 7000lbs and the trailer is 6805Lbs. Should I replace or add to the factory installed cooler? Thanks bob

    Are you referring to the factory auxiliary cooler? If towing in the upper weight limits I would upgrade to a bigger (more efficient) cooler. Have not done so myself as I quit towing a few years back but may do so in the next year after the boat build is complete. PM Remmy and ask him his opinion on aftermarket transmission coolers as he has done the research.

    Whatever you decide, adding another cooler or upgrading the size of the installed trans cooler, you should seriously consider adding a Magnefine trans ATF filter also. There are numerous threads on here about using this filter for the ATF and also another for the PS fluid.
