Just came from getting new tires put on the car, mounted, balanced, alignment w/ Steeda C/C plates. etc. a few minutes after leaving, i now feel this vibration. It feels like an internal vibration. It is not present in the steering wheel. You cannot really hear it (i.e., exhaust pipes hitting the underbody). It feels like a grinding vibration, and you can feel it through the gas pedal and shifter (AOD). loose Change in the console will also rattle. It only happens between 23 and 2500, then goes away. 1st through 3rd gear vibrate in that 23-2500 window, and still in OD, just not as pronounced. If you keep it in park or in neutral and rev it to the same RPM's or above, there is no vibration.
Any ideas on what it could be or how I should troubleshoot this?
Thanks~ jeremy
BTW, I do have 4.10's and an FRPP alum. DS, and have had them for more than a year w/ no problems... motor mounts were also replaced w/ HD ones less than a year ago.
