my speedometer was messed up . when i went to fix it i found out that the small plastic gear that runs it was chipped off. Can i just replace that gear? or will it just happen again.? what are some causes of this?
-
Yes you can replace it. Age is the only thing I can think of that would break one, the cable could kink/bind but I wouldn't think it would break teeth off the gear.
-
soo you dont think if i replace it that somethin inside will do it again?
-
That's how they calibrate speedos, by replacing the plastic gears. hopefully your's is not in the tranny floating around.

do you know if the gears are the same on a th350 as the one in the granny fourspeed manual that came out int hose years because i have several of those
