Clean and Easy Installation.
Searching for a better alternative to cutting and splicing your factory hard lines when installing a Tru-Cool transmission cooler?
Look No Further.
If you've already installed an auxiliary transmission cooler and are looking to upgrade your lines to a stronger and safer setup, this kit is for you.
Note: Will work on any cooler with 5/8x18 inverted flare fittings.Our line kits are design to bypass the radiator's transmission cooler and run directly from transmission to cooler.
Please check compatibility tab prior to ordering.

Thanks Spencer for the top of the line customer service and sending extra parts with the transmission line kit to complete my installation.
No leaks everything is good quality
I went with their bracket and the biggie cooler, so naturally I had to go with their kit. It has all the goodies, nice lines and priced fairly moderately. It came fast and packaged well, looking forward to the install. (well not dripping trans fluid everywhere, but hey, when in rome)
I have nothing but high praise for Kloc Fabrication. Spencer went above and beyond to help me what even seemed like after hours to continue emailing me to answer my questions and make sure that I got the correct products that I needed. He also sensed that I was in an urgent need so he offered expedited shipping and when I didn’t see both options that he had mentioned, I paid for the fastest delivery and he made sure that I got it next day! SUPER SUPER customer support and service!!! Something not seen very often in any line of work these days. If you need anything in the fabrication line please give KLOC FABRICATION A LOOK!! You will not be disappointed!
Was pleasantly surprised to get a hand written letter thanking me for my order ! Very nice ! I took a chance and ordered a few fuel lines . Great quality products and good prices.
Kloc has the best trans system cooling kits and customer service! This Tru-cool 40k kit was installed on a 2020 escalade. Plenty of hose and all the fittings were perfect! Install was very easy as always.
Super happy with my purchase. Exactly what I needed and very high quality hoses and fittings. Thank you
Great products and service. Fast shipping and good communication when I had questions. Highly recommended

The line kit was well put together, and the length of line was perfect. Fitting fit great with no leaks. Should have checked the factory lines out a long time ago.
