    Trans cooler leaked with included fitting. Luckily I had parts left over from other kits I’ve installed. Replaced the fitting with one I had but wasted hours trying to make it work. Should have had another shipped asap to fix this. Not satisfied with the transaction.

    Tru cool max is the correct name for this trans cooler!

    Installed in my 05 Escalade and dropped trans temp 60 degrees!! Trans temp was running 200 degrees with oem cooler now I have to push it to for temp gauge to rise to 140!!! Bought it so I can pull my 6,000 lb boat with no worries!! Great cooler! The only thing I did to modify the hardware sent with the cooler is I drilled out the hose barbed fittings with a 1/4 inch drill bit in a drill press cause they looked like they would have been lots of restriction with fluid traveling through them! Very clean install!! Buy with no doubt in your mind that this cooler will preform as advertised!

  • Top critical review

    Nice product

    The cooler came as it was described with all the hardware for a factory connection. However, it would be nice to be able to have the option of ordering the correct AN fittings at time of order. If you plan on changing out your factory transmission lines along with the cooler you will need aftermarket AN fittings to go along with the new transmission lines that have AN fittings installed on them. Those brass fittings that come with the cooler will not fit the AN fittings. I gave the cooler 3 stars for this reason. Would have given 5 stars if the cooler had the option to order the AN fittings.

  • Excellent Product

    Well constructed and easy to install. Used 3/8 steel tubing with flare nuts (5/8 thread) sourced from local auto parts store. Installed with ports oriented up to ensure complete fluid fill to maximize efficient heat transfer. Excellent quality and lifetime warranty. Mine was made in Canada.

  • Great cooler.

    I have yet to verify trans temps reduction under heavy loads, I suspect from its design and larger surface area that it will function as others be reported. Do know that it does not have a burp tube in it, (instructions did not call that out looked inside to verify myself), so be sure to mount it inverted, (fittings pointing up), so that it will fill completely otherwise it won’t and is no more effective than the teeny factory unit. Plenty of videos online showing how why this is.

  • Do you value your transmission?

    If you live in high temperature areas, if you value your expensive transmission, you should get one of these tranny coolers. Great build, value, and product. I have not installed it yet, and I will come back and add my experience. I have used many tranny coolers previously, so this is not a new subject to me, but I will come back and give my review. Jay
