Default sc4 bumps when slowing down def not brakes

my tranny seems to have a bump / vibration when i slow down under 10mph whether braking or not...

anyone else have this problem? what is the cause and how do i fix it. its annoying.

i've been searching for a while and found plenty of vibrations and shakes but nothing similar.

Mine has a similar problem.
Except I know it's my brakes...
My rotors are shot and I haven't had a chance to swap them out. I have new rotors ready to go in but it's cold. And I'm not even driving the SC in the Winter.
It feels nice to be driving the ES, saving a lot of money on gas. However it is not as fun.

Do you have aftermarket rims? Could be they're bent.

i had 19s on before and but now im rollin stock and i felt it in both cases... if i let the car slow to a stop without pressing the brakes at all, at the 10 mark it jerks for a second. im thinking its something with downshift at second to first or first to neutral?
