yep there is a gear down there when you pull it out to check it if it look's in good shape put a electric drill on the end of the cable and get someone to watch the speedo turn the drill on and see if the speedo moves could be the gear on the tailshaft of the trans

I have had this cable off a month or so ago and the gear on the end of the cable appeared to be in good condition; also, I spun the end of the cable and the speedo worked fine...I am thinking it is whatever this gear plugs into is the part that is broken, does anyone have any idea how to fix that? :3:

I would guess that the teeth on the gear are shaved off a bit and the faster you go, the more it catches and reads properly, I'd pull the gear out of the trans and carefully inspect it, also look at the gear inside the trans to see if it looks like it's moved on the shaft or is missing teeth.

Thank you. I'll take it apart and see if I can hopefully identify and solve this problem

If it's the gear inside the trans you will need to remove the trans from the car and have it replaced

that would be a major pain...I was wondering if its possible that the cable is the wrong length? :2: since it kicks in when I'm in fifth and not when I have the car going fast in fourth gear

How do the gears look??

I'm hoping to get it on the lift within the next couple of days to take a look...if my memory serves me right tho the end of the cable was fine...it's so weird how it only works in 1st and 5th gear...
