Aah good point. I forgot to mention that the previous owner installed a new tranny. He put on a trans cooler and a shift kit. Also forgot that I had a tow package... :bang: It's been awhile since I had that truck...kinda wish we had kept that and gotten rid of Phil's Dakota 4x4.2-Strokes 4-ever said:If your vehicle has a trailer-tow package you ought to be fine. The power isn't an issue with the 4.0. But trust me, I burned up a transmission in you're same situation. Invest in an aftermarket trans. cooler...not real pricey, and you can mount/install yourself.
