    Hi guys,

    I currently have a
    $51 Hayden 678 Universal Rapid-Cool 9.5” x 11” Add-On Transmission Cooler – Not for Direct Replacement of the OE Cooler
    Hayden 678 trans cooler on my truck and will be towing a travel trailer a little over 5000lbs which I think is the current rating for the 678. I read that installing the 679 is not nessacirly a good idea for people who live in cold climate which is where I live. It can get pretty cold here in Canada, lol.

    My opinion is just to leave the current one I have now, any suggestions?

    Also, I hear people bypassing the radiator which is not how mine was done, does the TRD model with the tow package bypass this?

    Should I install a thermostatic bypass kit on mine?

    Thanks for the help.

    the OEM trans cooler as far as i know has a thermostat in it that allows the trans to heat up for that reason
