    Cooling for an auto transmission in your conversion is no small matter. Keeping a transmission cool is absolutely key to a long life. We have several products that are top quality, durable, easy to install, and offer the best balance of cooling for your rig.

    We've developed some real preferences for transmission coolers, and this stacked plate style cooler is efficient and durable. The Dana version measures 11" x 11-7/8" x 1-1/2" thick and the Northern version measures 9" x 10" x 1-1/4" thick. It comes with mounting ties and hardware. It fits well into the space in front of the radiator (and AC condenser, if equipped) and behind the grill slats of CJ, FSJ, XJ, YJ, TJ and JK Jeeps with conversion transmissions and engines.

    Tank, overflow, polished stainless, 3" x 10", includes cap and bracketry

    This is the overflow tank we reach for when doing a conversion in pretty much any Jeep. We love the stainless steel construction, simplicty and ease of mounting. They take up little room and can tuck into a variety of locations. It will outlast all of those cheap plastic ones from the factory.
