What codes need to be deleted with a 4l80e swap? I have an ls1 pcm and the harness was built by efi connection with the 4l80e harness. My tuner did a segment swap and I beleive thats it? I drove it the other day for a few minutes to max mph of 15 and it didnt seem right. I brought my pcm to the tuner and he put a SD tune on it with the segment swap. Just wondering if there is more to the tune that he needs to be done in order for the trans to work correctly? That was the first and only time I drove the car, I'm out of town but I plan on messing with it more when i return.
thanks
