    Okay quick question. How do I know if I have a trans cooler on my truck. I've been reading on here about them but never really paid attention to if my truck had one. It was 3.73 gears and came with the tow package, but no braking system.
    Thanks in advance.

    There should be a small "radiator" in front of the main radiator. That would be your trans cooler. Also there may be two small lines (almost look like brake lines) going into the main radiator that also is a trans cooler.

    There is 1 more way to check to see if you have a Trans Cooler, that is in your Glove box there is a White Sticker, that has your Vin Number and a series of Letters and Numbers.......These are RPO codes they will tell you what your Truck has been build with.......The RPO code to look for is Z82,that is the Heavy Duty Trailering Package.....The Trans Cooler is part of this Package.
