Well, after a little minor problems, I switched from an auto to a T5 and now I get a check engine light, setting a TCC code, now my question, would it be possible to solder in a resistor in the tcc harness between the feed and return wires to the ecm, since all it is looking for is a change in voltage?

You could do that, or disconnect the dummy light. I'm not sure what you would use to do that though...

 

Yes, this also works for temperature sensors on the newer f-bodies. You take a resistor and solder in place of the sensor. Just look up what the sensor is supposed to read and go to radio shack and pick up that resistor. It should work fine.

 

Well, now it is giving me another code, a code for a no vss, my car is cable driven speedo, so where is the vss signal derived from.

I did the t5 swap in my 84 and i get a vss code too, only when i drive on the highway... My car also has a cable driven speedo..

 

your car gets the VSS signal from the back of the speedometer after you pull the cluster out you will see the sensor

 

why does a mechanical or cable driven speedo recieve a vss signal? That is weird......How can a correct the problem?? Thanks Kevin

 

The speedo does not recieve the signal, the cable just turns the VSS sensor behind the speedo, then the signal goes to the computer so it knows how fast the car is going, and if you have cruise control it uses it too.

 

Thanks for the help I am getting a converter for the signal at the trans and it is supposee to plug in and run the cable.......from what I could gather from the guy I'll keep you posted and let you know how it turns out.
