my 98 Subaru Outback jerks whenever I turn left and right slowly.. whenever I turn to different direction slowly and pressing the gas pedal, it does jerk. but when I turn left and right fast, it doenst jerk.. I had a transmision flush so I believe the fluid is still good.. The steering fluid is good as well. thanks
