  1. Engine & Drivetrain
    About a month ago, my Acadia started rough shifting. I have about 40k miles. I don't really know how to explain it other than it seems to hesitate before changing to 2nd gear. I wouldn't say it's like a slip, it's like a hiccup. Like you think it's going to and then it does... Make sense? Ideas?
  2. Towing & Hauling
    Here are some questions about adding towing 1. Would you just add the HD radiator or, leave the existing and add a transmission cooler? 2. Which radiator would you purchase - Ive been looking on RockAuto. They list two different Genuine GM parts 21818 and 84079536 . They both say HD. Not sure...

  7. Engine & Drivetrain
    I have a 2013 Acadia with ~108k miles on it, which I've owned for a little over a year. A few days ago, I had several issues all pop up at the same time (listed below). As suggested in a couple of similar threads, I replaced the Brake Pedal Position Sensor and cleaned out the Throttle Body...
  8. GMC Acadia
    Hello everyone. I am a long-time Acadia owner (since 2010), but new to this forum. Can anyone tell me what the best diagnostic tool to use for the Acadia? My check engine light just came on yesterday and my wife told me the transmission was slipping. I really want to see what the problem is...
