    Tests have proven that a 20° drop in transmission fluid temperature can double the life of automatic transmission components. Cooler tranny oil gives more reliable, consistent shifts under racing conditions, and prevents transmission damage under extreme towing conditions. These transmission coolers provide a reliable means of cooling your auto transmission. Cooler capacity is based on GVW rating. Select cooler size based on severity of service.

    • Multiple GVW ratings available
    • Easy-to-follow instructions in English, French & Spanish
    • Billet Fittings - Billet barbed or AN fittings offer more secure hose connections

    Rated 5 out of 5 by from Shiny I purchased the flex-a-lite transmission oil cooler about two weeks ago to put it onto my 4.6l ‘01 f150 supercrew with the 4r70w transmission. It comes with all the necessary mounting attachments to direct mount it to the front radiator with the little zip tie looking pieces and rubberized spacers. Instructions are adequate. Overall it seems to be a solid built piece.Cheap Chinese steel? Maybe. I’m not some metallurgist that can tell the difference if it is or not. The soldering job on the coils look pretty good. Was well packaged and the fins were not all crushed in or anything. I do wish it came with two rubber hoses and that they were longer than 4 feet, but for Thirty bucks it beats the price on what one of these cost at the local auto parts store so I can’t complain.

    Rated 5 out of 5 by from Works awesome Installed in minutes, really helps transmission temp. Only slight gripe was that a half Palm sized portion of the fins were bent and I had to spend about an hour carefully straightened them. Wasn't from shipping as it was packed well. Please tell your warehouse workers to be more careful. Otherwise great product great price.
