    2009 Outlook, Acadia, Traverse, Enclave Transmission Tune Help

    I need help tuning my wife's 2009 Outlook. The factory settings are driving me nuts and I would like to take the family on vacation this summer. The biggest issue seems to be the constant slippage when the TCC should be locked. I'm going for MPG and reliability. Thanks in advance for the pointers.

    Here's a couple of files to compare. I would really like to know if I'm on the right track. The TCC won't stay locked around 80 mph.
