Grinding sound when shifting from park/reverse. Chevy Impala.
Just got the pressure control solenoid replaced with a new one in my 04 chevy impala. Now she shifts like a dream. No more hard shifts or stalling when accelerating. Problem now is whenever I shift from park or reverse to drive it makes a grinding noise for about 2 seconds when I start accIelerating. It only makes this noise when I first shift out of park/reverse to drive. And I never had this problem before the PCS was replaced. Can anyone tell me what's wrong and the severity of the issue?
