nurkvinny Posted January 3, 2009 Report Share Posted January 3, 2009 My dad has a 97 3/4 ton Chevy 4x4 truck that needs a transmission. We found a good deal on a 4L80E trans and case from a 94 2500. Question is... if we make the lines and harnesses match up, are there any issues with the 97 computer running the 94 trans? Thanks. Quote Link to comment Share on other sites More sharing options...
