Machined from aerospace-grade billet aluminum in Wichita, Kansas, the kit includes a short front fitting, a long rear fitting and two O-rings, and it uses the standard GM transmission case thread (0.516\" O.D., 1\/4\" NPSM thread). Whether you are building an upgraded cooling loop for towing, racing, or improved longevity under load, these adapters give you a durable, serviceable interface to attach AN hoses and external coolers.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these adapters attach to my 4L80E transmission?\u003c\/h3\u003e\n\u003cp\u003eEach adapter screws into the transmission cooler ports where factory fittings or lines normally connect.
