Hey guys,

So of course all the sounds my car has been making are the same as last year. The police siren and whistles and all. I just ignore them now since it only happens when its below 35*. But recently my car is starting to shudder a bit when i'm cruising with the car in 4th (J-gate), and then let off the gas. Whole car shakes forward and backward. Only happens sometimes. I downshift to 3 and it doesn't happen. I put it in 5 and it's not there. Then I put it back in 4 and it comes back. Eventually it stops about 1-3 min after it starts. But my car has never done this before.

What do you think it is? Could it be the transmission?

Thanks,

MD
