I have an 88 Camaro I bought cheap from some dude who obviously didn't know what he was doing. I did a search for this but didn't come up with my exact issue. The speedometer does not work (this includes the odometer). I'm told by my mechanic that the speedo cable was laying on the headers and burnt through. Said it'd be $250 just for the replacement cable. Advance has one for $15. Chilton says something about hooking it from the gauge to the brake booster for the non cruise control cars (which this one is). Is it really so simple as to just pull out the cluster and run a new $15 dollar cable from the gauge through the firewall and to some connection on the brake booster or am I missing something? I thought these things went to the tranny (auto)? Anyone have a picture of this connection? My cable's gone and I haven't seen any hole in the firewall.

 

Run like a mad dog from that mechanic! By 88 there should be no transducer, so you should be able to unhook the cable from the cluster and trans tailshaft (the cable is clipped to the frame in several places), and pull the cable through the firewall.

Thanks again, sir. I'd read that sticky before...I can't believe I forgot about it. To confirm what I've read, I need to pull out my gauge cluster, lube up and attach my new $15 cable and casing, run it through the firewall, find some clips running along the frame (I'm not sure if the rest of the cable is there or not) and attach it to the tranny? It's a 700R4. I'm lost on transmissions. Where on the tranny am I looking for the other connection? Thank you. BTW, that mechanic had my car for almost 3 months and told me he was working on all the problems and only managed to rewire the ignition system and hook the y pipe back up to the headers. It's been back with me for a couple weeks and I've made vast progress on it, just a couple problems left.

 

The new cable may be pre-lubed. At any rate, you don't need to remove the cluster if you're simply replacing the cable. I'd pull the old cable and trace how it's installed (providing it's still in place). The cable will be attached to the tail shaft of the trans. The old cable will be there--or you'll have a gapping hole where it should be, along with a trail of trans fluid.

Alright. Thanks for all your help.
