Jerking

Mine began doing something like that shortly after I got it. Some might call it a death wobble. After I got up to highway speeds, the whole front end would shake violently and would only go away if I slowed back down to about 45. It was found to be caused by warped brake rotors.

Now, if the transmission were responsible, I've no idea to do.

its definatly not a death wobble its not coming from the front end at all and all the fluids are at the right levels im thinking maybe its the cat its just weird cuz it stays in overdrive but just bucks alot once you hit about 65 and try to accelerate

I would check your front CV, check to make sure the U-Joints are still in decent condition. When you get it bucking or shuttering lightly push the brake, just enough to get your brake lights to come on and see if that takes the bucking away. That is testing the torque converter.

Try turning off your OD and see if it still happens.

Possibly ignition related - does it feel like the motor is stumbling/loosing power and then surging?
