This kit enables the driver to control the operation of the torque converter at a desired speed, even in 3rd. gear if you wish. Connects to the square 4 pin square connector block on a 700 R4. On this setup you do not use a pressure switch, as some 700 R4's don't have a removable plug on that oil pressure port. This is controlled exactly like a cruse control, touch the ****on to lock it up, green indicator light comes on, tap the brake to disconnect, simple as that. Comes with necessary parts, easy to follow instructions and full diagram, all you need is some wire and connectors. Tom theorize@yahoo.com
