yep but I know Pat Barret for more than 20years back to when he owned his first tranny shop. He can and will modify just about anything you bring to him...He just does not have a kit for it... Probably the best drive shaft builder in the US is close by me in Salisbury, NC..madhunter said:Level 10 doesn't list the 6T75 as one of their transmissions to rebuild. Max tq rating is 300lb/ft. I reiterate that modifying one of thesese for a G6 may be OK but the load for moving this beast is much higher. I would suggest if you have this donw to not go much bigger than stock tires to keep your tires as the limiting factor. There are a lot more components than just the trans (diff's, shafts) that may need strengthening.
