We offer radiator adapter fittings for the 2000 GMC Sierra to allow installation of a transmission cooler without having to cut and flare lines. Derale part # D13018 is a set of two 5/8-inch inverted flare fittings, one male and one female.

If you do not already have a transmission cooler you can choose the largest size that will fit in the space available for mounting; coolers are not actually vehicle-specific. The linked article provides a lot of useful information about types of coolers and placement options and the link to our parts page for coolers will show you several specific coolers that will fit your 5.3L Sierra.
