Derale transmission cooler. Swapping to manual transmission so no longer need. Can be switched from puller to pusher fan. Comes with derale fittings to adapt from stock transmission hard lines to 1/2" hose fittings. Also comes with thermostatic switch and 30 amp relay and wiring. This was on my k5 for about 3 months or so, maybe 500 miles. This fits behind stock grill with no cutting. Will ship on your dime. $100
