    I just bought a 1979 Ranchero and the speedometer and tachometer don't work. So right now I'm trying to fix the speedometer then I'm going to move on to the tach,but I don't know we're the cable for the speedometer is on the transmission mission. So if you could describe,show a picture,or send a video it would help greatly

    What transmission do you have? On both my F250 (C6) and Ranchero (C4), the speedo cable goes into the tail housing on the driver side. There's a single bolt that holds the cable clamp to the tranny housing. It can either take a socket, or a Phillips screwdriver (socket is easier). The cable goes from there to the firewall, where it sneaks into the cab.

    When I got my Ranchero, the PO neglected to put a gear on the cable, so my speedo/odo didn't work. The gears are interchangeable, though, so you can swap them to get close with the rear gears and tires. Your setup might be pretty different, though, since it's a '79.

    Do any of these shapes match the pan on the bottom of your tranny?

    I'd suggest looking on the door sticker, but if it's not stock (like Babe's) it's no help.

    Behind transmission mount,left side,you should see a black cable going into side of tail shaft housing.Remove the one bolt holds fork hold down.Wiggle cable assy. out of tail shaft and inspect plastic gear.If Ok,give gear a spin,have someone watch for needle movement.
    Blue plug is cable drive in top pic.Welcome to the site!Good luck.
