Everything was fine. Highway got congested so I went over median. When i came off the curb truck would only rev up. Checked linkage and it stills moves when shifting. Checked fluid and its all good. What could have happened? Help please!

Since you’ve been under the truck, I assume you didn’t knock the driveshaft off, right? Did the transmission pan have a dent in it? If so, likely the oil pickup tube is no longer in the fluid.

I think you need to tow it to you transmission guy and have him take a look.
