Just recently from take off my truck feels like its pulling a trailer. I was messing around in the snow a little bit (2wd) and it just started doing it. Any ideas what is wrong?

Have you checked your brakes? Does the engine sound normal? Do you notice any difference in takeoff performance when you put the shifter in "1"? Is there a trailer hitched to your truck?

I'm hoping it's that last one.

Could have jammed something on E-brake line.

could be a bad knock sensor sending the ecm into fail safe mode.

After it happened I parked the truck. I went out to start it, started it up and the O/D light on the dash was blinking. I hit the O/D button, it stopped blinking, and it ran fine. Not sure whats up with that.

you could have just gotten snow snow/ice/water in the electrical connector on the transmission.
