Does anyone know what sort of power the stock JK 6 speed manual can handle? I plan on doing an LS swap, but I'm unsure if the stock tranny can handle it? I'll likely not swap in an LS with stick HP either. I'm thinking of swapping an 6.0L LQ4 that will have min 500hp hopefully as much as 600HP... I doubt it will handle those sorts of numbers, but I'm curious what it can handle?

Hi, JeepKing...This is a Mercedes-Benz NSG370 aluminum case unit that will handle a Pentastar V-6 or stock LS engine.  500-600 horsepower would have me searching for a much heavier duty unit than this one.  Ratios are decent, what kind of use do you plan for the JK Jeep Wrangler?

Others willing to share experiences with this transmission, used from 2005 up in Jeep vehicles?
