    Under Shift Pressures, General, the Pattern B Shift is changed from Y to X. The TUTD MAN Shift is changed from Y to X. The pressure pattern modes for Y and Z need to be put back to special from normal. These changes are likely causing your issue.

    Under Shift General Tap-Up/Tap-Down IP display should be changed to enabled (not sure if this really matters). However, on files I've used for Camaro's with tap shift these tables need to be changed back to stock.

    Under General, Max RPM is 4,000 instead of stock 5500 for CMD Gear Control Limits.
