Transmission doesn't know what it wants to do. There's times that I'll turn a corner, the car continually bucks and jerks without my foot changing position on the accelerator. Jerking is hard enough that it puts my head into the headrest several times. There's also times that I'll hit the accelerator and the car will make a bunch of noise like it wants to go, but it won't move. I have to then hit the accelerator even harder, and you can feel the car jerk and finally start to move like it's supposed to do.
