When I had 4.10 gears installed in my rear last year I also bought a speedo gear for my aod trans to get accurate speed on my speedometer. I recently removed the speedo cable and found the gear all mangled with several teeth missing. Its a plastic part . Thing is the speedo worked fine. I am going to replace the gear but should I worry about the missing plastic teeth. I am taking the trans out for a new engine. Any thoughts on this ? Thanks and happy holidays

who made the speedo?

if it was white...thats a 23 tooth....and ford doesn't make them at all.....it is also for a 5-speed and has the wrong pitch...thats why they wear out fast.

not much you can do...to make it accuarate you need to replave the output shaft because the internal gear is machined into it.

replace it every year or so...and no don't worry about the pieces.

I got the gear from CJ pony parts it is black . They are good folks, Im sure the plastic gets hot n cold and cracks with time. Im gonna throw a new one in and call it even. They only cost $10 or so.

I have the same problem. There is nothing you can do but replace it every so often. Unfortunately the white gear is the most expensive, but it's the price you pay when running 4.10's.
