1985 3.03 trans speedometer problem
My speedometer quit working. I replaced the cable and the plastic gear on the end of the speedometer and now it works on occation, usually after the truck has been running for 45 mintues. But, it bounces and does not register the correct speed - 45 mph when I'm doing at least 65. I can do a 35 mile trip and the odometer will register about 6 miles, thats how much it does not work.
I think I have a rebuilt Ford 3.03 trans. It has the two side shifting rods and originally it was a 3-speed on the column but was replaced with a floor shifter. The engine is a 300.
I can feel the gear that drives the speedometer in the trans with my finger but I'm not sure if it is made of metal or plastic. My concern is that the trans gear is either worn or has moved.
Any ideas on what my problem may be and how to fix it? Can the gear in the trans that drives the speedometer move? Thanks.

Hello , the gear in the trans can get worn. I have an F-150 with the same problem. I would sugest when you can to remove rear tail shaft housing and replace that gear, that is what I will have to do to mine. Most of the ones I have seen are nylon gears, Mike
