3.73 Gears with Auto Supercharged GT
#11
Picked up car today. Gears were 3.31 stock. The 3.73 feel like a good choice. I was concerned about being over torqued. I feel more when I stomp on it from stand still (break loose pretty easy) but beyond that drives nice under normal conditions. Seem to be a good compromise.

3.73 are more ideal for an auto than 4.10 on the S197 with 5r55s. The reason why is that the first gear in the 5-spd auto is short than the first gear in a 5-speed manual to make up for the added drivetrain loss in the auto.
They did this to make the 0-60mph times equal between the two trannies.
