The weather has been getting warmer, albeit today was rather cool.

I have noticed when the car is warm that there is a vibration (at idle) that intensifies as the car gets warmer and the longer it's driven. The vibration doesn't show up when it's first started and probably isn't apparent even within the first 10 minutes or so, but on my way home at night when it's above 70F outside I notice at every stoplight I hit the vibration gets worse. After I get moving again nothing feels wrong, but when I get caught at a light I get this nasty vibration.

I'm wondering if this is a sign of trans pump or torque converter failure?

Any clues? Anyone?

Thanks for any advice
