Newbie here, The speedometer in my Ramcharger is no longer accurate. It reads about 50 to 55 at an actual speed of 75. It does not jerk around , just slow. If someone could point me in the right direction, I would appreciate it. I did replace the speed sensor at the rear of the transmission but that had no effect. Is their a business that repairs failing speedometers? Contact information would be great. Will the truck still run with the speedometer removed? You all have been so helpful in the past and I thank you for that.
