Re: speedo

I would have someone pace me at different speeds in a newer vehicle to check the speedo. I don't think any conclusions can be drawn from the situation you are describing. Just my thoughts....  LockDoc

I would do this first. Who knows your diff gear ratio may have been changed or different tire size will give a bad reading, then you would need new speedo gears in the tranny.

Re: speedo
well it looks pretty easy to take out, and if it matters the trans as been rebuilt, it went out on the trip home when i bought it so ive driven the truck the entire time ive had it on a rebuilt trans, and when i got it the speedo didnt work at all but when i got it back from the trans shop after the rebuild it works, so that would mean the gear in the trans was worn out or broke or something so could the gear in the speedo itself be worn out to??? i dont know what exactly is inside the speedo
THANKS FOR YOUR TIME
