4l80e trans connector conversion to 4l60e information
I purchased a standalone harness from a company, it was designed for a 4l80e but i went a different route and got my hands on a 4l60e for cheap. Was wondering what wires i need to swap exactly to convert the connector to work with a 4l60e trans. Thanks

Here is a link to go from a 60 to an 80 so do it in the reverse order & eliminate the front speed sensor.

Also you need to get a different tune as the 2 transmissions work differently
