Bought a ‘99 3500 4x4 that had a 6.2 installed in place of the bad 6.5L. The exhaust and breather had to be altered, but it seems ok. The 4L80 will not shift correctly but I’ve heard you can use a TCM from a different application or get a stand alone TCM. I’m not worried about anything other than drivability. Not trying to break the bank on a old work truck.
