I have a question I didn't notice when ordering: my 08 has a button on the shift lever for tow mode / OD off for towing . Does the new 8 speed with a shifter knob on the dash have the same capability?
Yes, the button is on the dash.
I've had 2 1500 5.7 trucks. I just tow and open trailer, but I have never needed to use TOW mode.
