    2008 Acadia Trans fine tune

    I'm looking to fine tune the shifting on my 08 acadia. Hoping that someone can tell me specifically what to tweak or adjust with the trans, torque management, etc. Any help is apprecaited.

    Post up your stock file. What are you looking for, quicker shifts, different RPMs, harsher shifts, smoother shifts, more MPG, more performance?

    I'm looking to increase the shift points or mph, under normal driving, it will be in 6th gear by 45 mph. Any tips or tweaks to help fuel mileage is a plus. This is the wife's daily driver, not looking for more performance unless its a by product of something else.

    I can tell you what I did yesterday and it made a world a difference just in the drivability.

    I set all the TCC apply/release speeds to let the converter slip in gears 1-4. 5th is lockup at 47, unlock at 40. 6th is lockup at 55, unlock at 50.

    I copied this from Normal to Pattern A, B, Hot. I did not touch TUTD.
