Only have 900 miles on my 07 V6 STS and have noticed a vibration from the gear shift. Have searched the forums here and can't seem to find anything directly related, but maybe I am missing something.
Transmission seems to shift okay, not quite as smooth as my 04 CTS, but still quite smooth. The vibration in the gear shift only seems to be there only at idle and at very low speeds. When I held my hand on my CTS, it was as smooth as can be. However, the shifter of the STS is really vibrating. Once I get up to 20 or 30 the vibration is gone. There appears to be a slight vibration felt in the steering wheel as well, but it is much more noticable when holding onto the shifter.
Anyone else noticed the same thing?
