Speed Engineering 4L60E to 4L80E Transmission Adapter Harness kit allows you to convert your existing 4l60e transmission to a 4l80e transmission. This harness is compatible with 1998-2002 Camaro/Firebird, GTO, and all GM trucks and SUV’s from 1996 to 2006. There are two separate components of the conversion harness. The first is the adapter harness that converts your current transmission plug and wires to the new 80e configuration. This saves you the trouble of repining any connectors. The second component is the Input Speed Sensor connector. This part of the conversion harness runs from the FRONT ISS sensor on the transmission to the ECM. This will give the ECM the correct signal it needs to operate the transmission. In order to complete the conversion you will also have to have the ECM flashed with the correct calibration changes for the 80e transmission.
 

Features include:

  • 11 pin Transmission Harness
  • VSS Harness
  • Braided cable loom

Note: Orange wire goes to Pin 22 and Blue wire goes to Pin 23 on VSS harness.

Note: Only works on 1999-2006 GM Trucks & SUVs for swap conversion. Does not work on 2007+ applications.
