Ok I know these things work together right?? Anyway after my gear swap my speedo now reads "faster" than I am really going. Driving about 25 in D (speedo reads "about" 35) the torque converter is locked up causing the engine to idle along at about 1100. Problem is just enough throttle to maintain that speed I get sort of a vibration cause it's lugging the motor. Also happens in OD around 65. Will changing the speedo gears change when the torque converter locks up??
