About the only thing I can tell you is check with a local dealer. They can check if any flashes/upgrades are available and applicable to your vehicle.

Most aftermarket "chips" are generally for getting more power - usually for the Hemi powered vehicles.

Generally any reflashes address a driveability issue. Changing the output parameters to increase mileage or power would likely cause certification issues.

There were a couple of flashes to improve false cam sensor and trans valve switch codes from occurring and improve hill climbing ability in reverse. These bulletins were released in 2009:

There was also a safety recall F08 to reprogram the instrument cluster (CCN) on some '06 ND Dakotas built before 2-3-06 where electrical accessoies could quit working without warning.

The hill climbing in reverse issue makes a lof of sense, since the engine seems to labor to back the truck out of my driveway which has a slight incline toward the street.

Would a dealer reflash under warranty or would I get charged?

"Would a dealer reflash under warranty or would I get charged?"

This may be a gray area and only your dealer can answer this question. Provide them with the last 8 of the VIN.
Under the EPA extended federal emissions warranty, any PCM replacement or reprogramming or catalytic converter that fails in service that affects emissions or performance is covered by a mandatory 8 year/80,000 mile warranty. http://www.epa.gov/o...er/warr95fs.txt
Your PCM and TCM are in the same housing and if one gets programmed, the other gets programmed.
Is a transmission enhancement an emissions concern? Maybe not.
It would almost be easier if you had a false engine fault code that the 1st bulletin addressed.
Can a dealer charge a diagnostic fee (or minimum charge) for the service? Maybe.
Dealer policies vary.
Some dealers will do a regular customer a favor and cover this in the interest of repeat car purchaser/service customer satisfaction. Some have a 'good will' kitty set up to cover favors for work that 'technically' isn't covered. Ask.
