"OD off and Tow/haul mode are seperate things. OD off only came on 2006+ trucks. You can check with your local Dodge dealer if you have a 2005 Dakota, as some dealers can program your tow/haul button to be the OD off button instead. You cannot change any of the settings in tow/haul because it is a seperate system from the rest of the transmission programming options. "

This was info that I pulled from one of the various forums that I browsed while trying to figure out the trans tuning. Im not sure if its seperate from the PCM, or just seperate from the OD off shift schedule so thats why you cant program it.

When in doubt, ask.

 

Really? All the Ram guys are stating that OD/off is different from Tow/haul. I may have to try this then. I would love to have a shift shedule for when I go out cruising that doesnt use OD so I dont burn it up.
