Hey guys I posted this on ls1 tech and no one has given me much, I know there is no real answers, but I just want some opinons before I go ahead with my plans. I have a 2k rcsb 5.3, it has 65k on it with headers, K&N, 3:90 gears, and Hyperjunk. My plan is to get a Nelson Tune with some Tq Mgmt removed and a Transgo shift kit and Cooler. The problem is, all I have been reading lately is threads about blown transmissions. I want some more performance, but not at the cost of my trans going out immediatly. I know it will eventually go out either way, but I would like to think I can get another 20k out of it at least. Basically what kind of life expentancy should I have after Nelson+transgo? I don't Drag the truck on a regular basis, but I do drive pretty hard sometimes. How long have some of your 60's lasted? Any advice or info greatly appreciated. What is your opinon Allen.
