I stalked the forums looking for info on how high the year you could go with compatibility with my truck and just couldn't seem to find any info on it. Took the advise of a guy at Collis truck parts in PA saying an 07 would fit in my truck. Just wanted to get a second opinion from the forum...
98 k3500 with a 7.4 got a 07 4l80e out of a 6.0 will it work? Internal wiring harness needs to be replaced on the 07 trans as it was damaged on removal. Went to buy a new one and I saw the harness changed after 03 to the new style. Thanks in advance
