DOESN'T SEEM TO MATTER IF IT'S RECENTLY BEEN FILLED WITH GASOLINE OR IF IT'S DEPLETED SOME. *TOOK OUR CAR TO THE LOCAL CADILLAC DEALER FOR THE WORST RAW GAS SMELL EVER WITHIN OUR GARAGE, WHERE WE PARK THIS 'NEW BLACK BEAUTY'.

ANYWAY, AFTER REVIEWING ALL OF THE MANY COMPLAINTS AND PROBLEMS LISTED ON VARIOUS WEBSITES AND THE OTHER XLR FORUMS, AND DETERMINING THAT WE ARE DEFINITELY NOT ALONE IN THIS REALLY EXPENSIVE SHIFT CABLE FIX, WE BELIEVE THERE'S A DEFINITE MANUFACTURING PROBLEM/DEFECT WITH THIS FAULTY PART!!
