When accelerating my shifter moves forward and up and when deceleration it moves back and down. I dont remember there being this much movement last year, but im not 100% sure on that.

So i was wondering about how much movement should i be seeing, and what would a common cause be?

I thought at first the PPF but most ppl say that causes twisting, which mine does none of


Thanks in advance guys

That's interesting. I had the same problem after I replaced my rotor motor. I don't that its a good thing to have happen. Check to make sure all your transmission mounts are tightened and check motor mounts too. Perhaps they have loosened. Also I believe that there are 3 braces underneath the car check those too. These suggestions are what I am going to look for on my car.

Have you done anything to your car, "A before and after", that you might think caused the movement?

I would blame it on worn motor mounts. There are a couple of threads floating around right now about engine dampers and torque dampers and braces, look into those to fix your problem.

So if there is a hole in your shoe, you buy extra socks? That's ridiculous.

The jist of the thread is correct - the PPF, differential bushings, and motor mounts are what support the drivetrain. If any of these develop wear or damage you can see increased movement in the shifter.

Don't put braces/brackets/bandaids anywhere until you're sure the OEM supports are all in good shape.

Pull your motor mounts. You probably won't be able to tell if either one is bad from a visual inspection while installed. Mine looked fine from under the car but, once removed, the drivers side mount practically fell apart in my hands. The mileage on my original factory mounts is 93k. Passenger side fine...drivers side was garbage. One note, if you replace with OEM, Ray is suppling a steel passenger side mount to replace the drivers side. Steel on both sides now.

Mine was doing a lot of that. I have relatively low mileage engine mounts but my diff mounts were original. I replaced my diff mounts with the Super Pro poly urethane mounts and about 90% of the shifter movement went away. Stock diff bushings are 15 years old at this point and probably worn out. They are a pita to install so plan on doing the fuel filter while you are there.


The motor mounts help keep the drivetrain from moving around from the front of the car where it bolts to the chassis. The diff bushings help keep the drivetrain from moving around from the rear of the car.

The stock diff mount bushings will typically ooze fluid when they fail. Easy way to check.
