I am having a problem on my 2001 SS that is worrying me. I got the TC installed less about 2 weeks ago.Everything was fine but there is this loud horrible rattle/vibration when in 2nd gear,1000 - 2000 rpm 25-30 mph.It gets louder and progressively faster as I slowly accelerate.It will slowly diminish then disappear as soon as I am out of that range stated above.I don`t know what the hell it is but it is starting to **** me off! My car is rarely driven and was fine before the install of the Yank SS 3200.Anyone know what it might be????
