I have a 700R4 in my 1987 IROC and the speedo cable is busted where it goes into the trans. Do I need to replace with same, or does a cable from a manual trans swap right over? If so, please provide year and/or model swap over info if you have please. I have a thread over in the classified wanted section for this and a member is offering his T5 cable, but we're not sure if it will work?

 

Help please...I'm sure someone out there can throw me a bone =)

 

All the same.

Either it IS a cable, or it IS NOT a cable. Except of course that it needs to make that hard 90° out of the trans so it needs that reinforcement thing on it. (either buy one that way or transfer yours over)

 

Just to clarify, it seams to me your saying that a cable from an auto or a manual trans are the same. I'm mostly concerned if the attatchment is the same. The car used to be a 305tpi with 5 speed (and busted speedo cable at the trans connection) and I swapped in the 350tpi with auto tranny, which also had a broken speedo cable in the exact same spot. That was over a year ago when I did the swap, and I can't recall if the cables appeared swappable or not (and I no longer have the other cable). This guy is offering a good cable from a T5 so I want to make sure it will attach before I buy and get it shipped.

 

The part that goes inside the trans to mount the gears may vary but GM speedo cables are all usually 7/8" x 18 thread at the connection

 

Easiest way to fix a busted cable is go to the local parts store and buy their cable replacement kit. Its the same braided cable just something like 6' long and has one end squared off and the other end you will cut to the needed length and add a little squared cap that gets crimped on. costs around $8 and is an instant fix instead of waiting for one from hawks or summit. Just did the exact same thing a month and half ago, make sure the cable is lubed up too!

 

The cables are all the same, as far as how they attach to the transmission.

Different cars may have different length ones though, so you gotta watch out for that. Has nothing to do with auto or 5-spd, or Camaro/Firebird, or 6-cyl/V8, or year, or model. Main thing that makes em different is cruise control.
