Well Scott, I'm generally pleased with the 6L80E. With the factory tuning of the G8 the shifts are very smooth under normal around town driving. When pushed, WOT shifts are less than impressive due to the factory tune with 100% torque management. It feels like it falls flat on its face between shifts. It is my understanding this can be cured with a tune to deliver crisp "tire chirping" shifts. Maybe Brian can expand on this with his firsthand knowledge. I don't feel that it hunts or shifts too much. It seems to find the right gear when downshifting while accelerating. The gear spacing is spot on. First gear is 4.03 to 1 so even with a conservative rear gear it will get out of the hole nicely. The G8 has 2.92 from the factory and most guys that are changing rear gears are going with 3.27. As for the durability issue, they seem to be a durable piece. I have read about two that have given up the ghost. Both were running boost. One had a twin turbo set up with an excess of 700 RWHP and lasted 18000 miles with many drag strip passes, with the ET in the 10.70 range. The other one I've read about was supercharged with a magnuson supercharger making an excess of 650 RWHP. His problem was slipping between shifts. The only thing they had in common was they were tuned by the same company so that may have been a contributing factor.(or, just massive HP) If you are looking to put the L76/6L80E or L99/6L80E combo in your vent window car, I think you'll be more than please.
