i have a 2002 dodge ram 1500 5.9l 4x4 when I make a hard left turn lik[url][/url]e when I make a u turn, my truck jerks when i straighten the wheels. Also sometimes when shifting from 2nd to 3rd gear the rpm's jump and the truck jerks.
check for a frozen U-joint. Jack up the front wheels and with the steering wheel turned to one side roll the tire on each side. does one stop or bind as you turn it? Do you see orange (rust) colored dust around the U-joint caps. Common problem on dodge. Doesn't have anything to do with shifting. Shifting sounds like your trans may be slipping between shifts. Have a tranny shop test drive it.
