Description

Our cooler kit can significantly improve performance and extend transmission life. Wear is reduced when transmission oil temperatures are kept to a minimum. Our kit uses a high efficiency stacked plate heat exchanger, and requires no cutting to the vehicles cooler lines and only very minor modification otherwise. Installs behind the grille, in front of the radiator.  Quick-connect fittings to the radiator and hard-line connections take out any guess work and ensure a leak-free installation.  The quality of this product insures you have a quick professional looking install. We offer this kit in either Black Braided AN lines, or rubber pushlock lines.  Click Here to see the choices. The rubber lines are good for 250psi working and 1000psi burst (10 times needed!). The rubber lines are factory looking in appearance for those who want a discrete install. Independent Review.

    I had the pc1200 with nylon/rubber hoses exterior radiator kit put on
    my 2008 Trailblazer mid week and it went in just as the instructions
    said. My mechanic who is used to working on performance cars (my
    other is a 1976 Corvette) told me that the components of the exterior
    radiator kit I purchased from you were the best quality he’d seen and
    that it went in like a dream.

    It was worth doing as the people at the shop assured me I didn’t even
    need to bother getting a temp gauge for tranny fluid as the addition
    of the second radiator was going to way more than take care of it.

    Thanks again…it’s in place and functioning.

    Got the rubber hose kit and installed it myself in my driveway. Read the kit ove a few times and really look at what you need to do to install it. Once I understood the instructions that came with the kit it was an easy install. You can find a similar trans cooler for less than half the price but to go thru the issue of trying to figure out how to install and mount it plus sourcing the parts I’m sure would be a nightmare. Go with a kit that has it all in one spot and is designed to work with your vehicle, ull see why it was worth spending the extra money.

    I’m very impressed with the overall quality of all the parts and how the entire package has been put together – I’m delighted with the fact that the cooler is made by Long Manufacturing! This is going to be an OE looking install – well worth the effort versus a generic off the shelf unit.

    Really impressed by the quality and craftsmanship of everything. Transmission cooler is nice and sturdy, brackets hold everything together nicely. Fittings are nicely designed and all plug and play connections that really make this the ultimate transmission cooler. I unfortunately didn’t check the transmission temps before the install, but after the install I drove it 15 miles and using my scan tool to watch temps. Temps stayed at 132F – 136F.
    Transmission cooler holds about half a quart of fluid if anyone was wondering. Transmission rubber hose is what I went with, wanted it to look more factory. I had about 6-7 inches of transmission hose left over. So, you have plenty of transmission hose to play with for routing. Also, customer service is fantastic. Got back to me really quick with 30mins to an hour. Highly recommend!!
