Compatible with 2000s GM Transmission Cooler Fittings
I installed this fitting on my GMC envoy so that I could add an auxiliary transmission cooler without cutting up the factory hard lines in case I ever wanted to go back. This adaptor was just the ticket. It fit into the radiator perfectly, nice and snug. It seems to be about the same size as the other hard lines in the system so it should not harm performance in any way, and it was super easy to install. The quality of the piece is good, The machining is perfectly acceptable for what it’s doing. It isn’t going into space, just driving to the liquor store. I highly recommend if you are planning to install an aftermarket transmission cooler and retain the factory radiator integrated cooler as well, grab one of these. Put the adaptor in the radiator and shove an hose over the factory barb. It takes minutes not hours. I have had mine installed for about 10,000 miles and have had zero leaks or issues of any kind

Work good on my 2011 silverado
Perfect fit for a fluid change in my 2011 Silverado transmission cooler. Made the fluid change a breeze paired with some 3/8” ID clear tubing.

Fit perfectly for an auxiliary transmission cooler
Fits just as well as the other named brand fitting but with more value for your money. Went in and locked in perfect into my radiator for running my auxiliary transmission cooler. No leaks or quality issues.
