What may be the name of this....
Ive heard that its a square cable that goes between the sensor to the rear of the trans for the speedo(pics shown). My local parts store has no idea what im talking about and it would help if i knew what the part looked like and what it is called. Lets go into some details, the car is a 84 firebird with the 700r4 trans, I have the main speedo cable that hooks from the speedo to this odd looking sensor(pictured), the there should be that other cable that connects to the sensor to the transmission. Please any help is wanted, need to find this part asap.
Thanks

The sensor itself is aftermarket. You'll need a really short speedometer cable to connect it. Different applications use them to connect external ratio adapters and such.

Not sure what that sensor would be for. Maybe something like a TCC controller, or an aftermarket cruise control. Is your car still computer controlled?
In any case, if you don't need it, just take it out and screw the cable directly into the transmission.

They're pretty much universal.
My diesel 93 Dodge Ram has a short cable like that to an external ratio adapter, might be a place to start.

If you can take the part to a transmission shop and ask them. They probably have the cable you are looking for or can order it. They can also tell you what that part is and whether you need it or not. Do you still have 14" wheels on the car? it might be an external gear adapter for the speedo if you have larger wheels.

I did'nt mean to let the tranny shop do the work - most of the good shops will be glad to help identify the part (if you get the "bring it in and we'll take a look" response - run). Take your pictures with you if you can't get the part off without cutting the wires.
BTW- after searching the web I'm pretty sure that part is called a "ratio adapter". You just need a short speedo cable to connect from the part to the tranny.

It doesn't look like a ratio adapter to me, though. Ratio adapters aren't straight through, they're offset for the gears, and they don't have wires hanging out of them. That's some kind of sensor.

Well im going to check the salvage yard this weekend and see what i can find, any cars in particular i should look at for cables? Hopefully there all universal...i hope. Id remove that sensor but then id have to rip apart my guage cluster(to lazy) and install a longer cable. I hope i can find a cable there. Will any size work?

I'm not a tranny expert or anything - it's just that the sites that did sell ratio adapters all had straight through adapters as well as the offset. Most of the sites stated the primary use was when changing the rear end gear ratio but I suppose if you put bigger wheels on a car the adapters could also correct the speedo reading.

look for gm vehicles at the JY. The speedo cables should all be the same for GM vehicles from similar years. If you're just looking for a short cable I'd guess that the FWD vehicles use shorter cables.

Btw, the cable that comes from the cable doesnt look like itll reach the tranny, if i were to order a new cable what size length would i need to buy? I keep getting all different sizes. Im also going to bypass that sensor and the cruise control and run it from the speedo to the tranny.
#23
I tried a few places and they keep giving me different sizes, also something about a upper and lower cable??? Then other places say that the 82-83 had upper and lower cables, not 84's. i suppose it would hurt to get the 80in cable, thats almost 8ft

If your car has cruise control, there are two cables. The lower one is from the transmission to the cruise control, and the upper one is from the cruise to the speedometer.
