Question on Performance Rear End ...A4
Need your help out here on the performance rear end. If an automatic goes from the 2.73 to the 3.15, will the speedometer gear in the transmission need to be changed or is it accomplished via the PCM programming?
Thanks for your help

No need for programming on any gear change for the speedo Shift points though will need to be adjsuted. The Corvette has the speed sensor reading off the axle, not the driveshaft.
