I ran the Juice/Attitude for 3k miles then upgraded to the Hot version for another 3k before having my tranny done. I drove in level 4, LBF 3, and defuel on 4-5 shift. I never did any boosted launches, but did drive it fairly hard. My allison clutches all looked good except for the C-3's, which were starting to discolor. Probably could have gone much longer, but thatr much power will eventually get to the stock Allison.
How much can you add and leave the tranny stock? I have heard it handles about 125 HP in upgrades, but I'm not clear on how long. What would be a fairly conservative number if you don't want to compromise your tranny reliability (too much)?
