Review on 18-inch 4L60E to 4L80E VSS Transmission Wire Adapter Harness for LS1 LM7 LQ4 5.3 by Staxy Asedr

Revainrating 1 out of 5

The strap is wrong! Attached incorrectly

Used modified for 2003 4l80. There was no 1st gear or 4th gear and he said the box was overheating. Passed the tune 4 times and got it right. I removed that harness and replaced the pins in the ECM harness myself and all the issues were resolved. Many pins are moved in this harness and only 2 wires need to be moved to go from 4l60 to 4l80.

Pros
  • Fingers crossed
Cons
  • Sad packaging
