    I am unable to switch my 12 speed automatic into Power Mode. It switches from A Econ to Manual and back but not into Power.

    Any ideas? Thanks!

    More than likely it's been disabled. Not all trucks are set up with both settings.

    If you're in a company, nothing you can do about it. Same thing if you're leasing a truck thru a company. If you own your truck, it's a simple fix in the ECM parameters.

    Thanks. I will ask the shop boss to hook it up and see if that is the issue. Im pretty sure the other WS we have do have the option.
