Default Speedometer Gear In Transmission

How do you determine which one you need?

Vendors have them listed as 18 teeth to 25 teeth, each one is a different color.

Just off a restoration and speedometer is not working.

Speedometer was restored by Ricks and cable is a new repop. i had the trans rebuild but not sure if he replaced the speedometer gear, but there was one in there when i hooked the cable up. I havent pulled the current one out yet.

Car is a 65 coupe with a 4 speed, 396. Originally was a 327/300 hp car.

Thanks!

Hi Patrick,

I just went through this and found the calculators get you close but fine tuning is needed so get a set of gears

You need to specify the installed axle ratio and tire size/revs per mile.

Update: there was an old gear in there and looked like the opening for the speedo cab was rounded off. Installed a new one and speedo works now.

now I’m off to check the accuracy of the gear.

thanks for everyone’s help.
