Questions & Answers

I have a 2003 hummer H2 with a 4L60e I am trying to upgrade the transmission to a 4L80e but not sure if the will work or shift gears but will the harness fix that problem&nbsp;

Asked by: Javier
The #22858 Holey GM Transmission harness will work with your 4L80 E Transmission. If your transmission is not shifting or you are not sure if it works the Holley Harness is not a repair item it just communicates from the onboard computer to the transmission.
