I hit a curb on the passenger front tire sideways going about 30-35 mph this morning trying to avoid a head on collision with a moron flying around a sharp corner on the wrong side on the road. Aside from a damaged rim and flat tire now my 4x4 06’Dakota won’t accelerate properly. (Like it’s stuck in a higher gear? Anyone have any ideas what that could be?`Preformatted text`

Is the speedometer working? If one of the wheel speed sensors is damaged the TCM won’t know the vehicle speed and will put the transmission in limp mode, I believe that is 3rd gear on the 545RFE.

Yes the speedometer is working. I’m not very handy when it comes to mechanic stuff. There is a small puddle of reddish brown fluid under the truck

The front differential may have been damaged when striking the curb with the front wheel, and is now leaking.
