Its probably the 3-4 gear clutch packs. Mine were going bad at the end of last summer, I did a cam, header, ls6 intake install and took it to the tuner last week. Well, my ailing 3-4 clutch pack obviously didn't like the stress of a chassis dyno. My 3rd gear is slipping really bad. Trans time. The upside? It still pulled down 382 hp to the wheels with a sick trans.
