Trans fluid clean?

 

Were you trying to make a turn with 4wd engaged?

 

Clean the Mass Air Flow Sensor and the throttle body.
Or if you have a manual transmission you could have a burned clutch with hot spots on the flywheek.

 

Need more info than 'my truck jerked'. Hell, you may have just run over something laying on the road for all we know...
Somebody will have you rebuilding the whole damn thing before it's over, otherwise.

 

LS swap?
