Got a '06 six year old Dakota 3.7 automatic I bought used earlier this year. Have put 4000 trouble free miles on it since new to me--when it had 45,000 on it. The scan tool says no codes stored.
Was wondering if there is any newer software beyond what was put there in 2006 that can be flashed into its computer to improve mileage and/or power since the truck was new? The truck is bone stock mechanically.

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.
