I have a 97 RCSB and did the 5.3 swap awhile back with the newer 4l60e and it blew up on me a few weeks ago and I have been doing without a truck because money has been tight, I am finally getting where I can do something about it and have a few questions. I have a local guy that has a 98 sub that he is parting out that he says has a 4l80e in it does this sound right and can it be used on a 02 5.3? If so I have hit the jackpot because he wants little to nothing for it. If this falls through I am just going for the level 3 from FLT but I would really like to go 80e because I like driving like an idiot...
