Ok just bought a 2001 sebring coupe. With a 3.0 automatic. So far so good except one thing. When i put the car in drive and hold the brakes it makes a grinding noise. After take off once the car is above a couple mph it seems to go away. Trans shifts nice and firm downshifts fine but once I stop the noise is there again.... Torque converter? I'm a mechanic but this one is throwing me for a loop as I'm a diesel mechanic haha
