On 4speed 4.7 Dakotas if you swap out the TCM located behind the driverside headlight (forget if its drive or passenger side I think drivers) for an 02 4.7 Grand Cherokee TCM itll give you the 5speed trans the only difference in them is the TCM which gives you the second O.D boosting MPGs I did this 2 years ago on my Dakota I will looks up some more details and provide more specifics they are out there. But anyone looking to up hwy MPGs a little will love this just an FYI

Isn't there a wire you can unplug also that will give you more "snap" on the shifts?
