Hello everyone, I know that several posts have been made about this but I would like to check if there has been a new solution. I have a 1991 Rs camaro with a manual T5 transmission from 1985. So as you can see I am with a vss but with a cable transmission. Dos it sells vss alone to put on my T5. I found on rock auto this vss ACDELCO 213197 and according to them it would be adapt. I am really skeptical because of the length of the shaft. so what would my options is?

Camaro 1986 Iroc-z
Camaro 1989 Iroc-z cabriolet
Camaro 1991 Rs

 

I went through this a while back with my Trans Am. The acdelco part number listed is for the 700r4 and will not work with a T-5.

I used one of these to convert from a cable speedometer output to a electronic speedometer signal. I believe the later Camaros such as yours used the same 4000 pulse per mile signal that was already in use on the Firebirds and Trans Am after 1986. Hopefully someone with Camaro knowledge will chime in since I don't know for certain.

J'ai vécu cela il y a quelque temps avec ma Trans Am. Le numéro de pièce acdelco indiqué est pour le 700r4 et ne fonctionnera pas avec un T-5.

J'ai utilisé l'un d'eux pour convertir une sortie d'indicateur de vitesse de câble en un signal d'indicateur de vitesse électronique. Je crois que les Camaros plus récents comme le vôtre ont utilisé le même signal de 4000 impulsions par mile qui était déjà utilisé sur les Firebirds et Trans Am après 1986. J'espère que quelqu'un avec des connaissances sur Camaro sonnera car je ne sais pas avec certitude.

En exécutant cela via un programme de traduction, je m'excuse si c'est en français cassé.

French..

No. That VSS is for an auto. The 5spd version is different and hasn't been available for at least a decade. You can either try to find a used VSS from a 5spd, or get a VSS that screws onto the mechanical speedometer drive and try to adapt that to read correctly.

Non. Ce VSS est pour une auto. La version 5spd est différente et n'est pas disponible depuis au moins une décennie. Vous pouvez soit essayer de trouver un VSS utilisé à partir d'un 5 vitesses, soit obtenir un VSS qui se visse sur le lecteur de compteur de vitesse mécanique et essayer de l'adapter pour lire correctement.

 

I think the best solution is to buy the converter that I found on classic Indistries, which is expensive

Maybe i'm reading it wrong, but the description says the Cable-X converts from an electronic signal to a cable drive. The OP is trying to go the opposite direction, cable drive to electronic signal.

 

Install a mechanical tachograph or operate a mechanical speedometer on a vehicle equipped with an electronic speedometer signal (sensor). You can do it — quickly and easily — at a cost far below that of buying and installing drive gears in the transmission. You save on the cost of buying and installing electronic tachographs and speedometers. Cable X lets you use popular, low cost mechanical tachographs such as Abbott, Argo, Sangamo, Servis Recorder and Veeder-Root, and mechanical speedometers such as Autometer, Clark Brothers, Datcon, Stewart Warner and Teleflex. It operates at accurate speeds -plus or minus 2%- on the most common OEM electronic speed signals, and is as easy to install as any electronic tachograph. You save hours of downtime installing gears into the transmission, and you don’t have to mess with troublesome, expensive and long cables.

 

How will that work with a electronic speedometer and a cable transmission ?

 

The Classic Industries adapter goes the other way... It generates a mechanical speedo drive from an electronic VSS. The 91 RS dash requires an electronic signal. Camaros up until the end of 89 used a speedometer cable. Most Firebirds started going to electronic VSS/Speedometer combos in 86. The T5 from one of those earlier cars should have a mechanical cable drive VSS, (same part as a TH350). So you need an electronic signal generator that will run off the mechanical drive. Once you've got the signal converted to an electronic signal you can worry about altering the signal to match what the car needs to see. That can involve sign wave to square wave, and different pulses per mile, and potentially adjustments for rear gear ratios.

The required signal can be verified in the service manual for the car. TBI cars still used a VSS buffer box to translate the signal for something or other. 7730 ECM cars have the ECM doing the translation. At the moment I can't remember if it's the cruise control, speedometer, or ECM that requires a different signal, but it's all in the service manual.
