just bought a 2001 ram 1500 slt with the 360 and 4 wheel drive. after having it for a week i noticed a tapping,knocking sound after it is warmed up it dosnt stop till your going over 50mph. brought it in they said it was the torque converter and pump they replaced it when i picked it up the noise was still there. they said it may need to break in and to drive it for 3,000 miles and see if it gets better or worse. im at 1500 miles and still making noise any ideas. they said that the tech guys never heard of this.
