Ok, before I drop the pan and change the filter and fluid. Can someone tell me that changing the fluid might help this problem. This happens in all gears, when I start from a dead stop the vehicle will hesitate then lunge forward. If I go really easy on the throttle it will not do it. Would this be a transmission problem? Or would this be a rear end problem? A friend said that it might be the rear, but I wanted to ask on here first.
