Help with a tranny tune in a 2005 C6 Corvette

[C6KID]

Hello, can anyone tell me where to start with a good tranny tune for a 2005 C6 Corvette. I swaped the rear diff from the 3.15 to 3.42 and it's shifting is all messed up.

The way to do this on a C6 Corvette is new gear ratio/old ratio= .921. Then click on the manual scale button & enter .921 and hit the commit button. Also change the T Err to 3.42 as shown.

Make sure that you start with the stock trans & TCC speed tables before you scale the trans shift speeds.
