Jakes D3 transbrake for a 4l80E 97 and newer. I swapped to a D1 brake and no longer need it. It was only used for a few months. Ill take 450.00 shipped. I payed 650.00 new. Also comes with a internal harness with everything pinned accordingly. Trans brake is wired to the F terminal on the trans plug.
Our Pro "D3" 4L80E transbrake is designed to allow transbrake launch from any forward gear. It was designed with the automatic shift by PCM or controller in mind. Ideally it will be launched from the D3 shifter position and shifted by the controller. Activating the transbrake button is required for reverse function. It has a revolutionary design for 3rd gear feed.
