Re: VSS issue and trans 1st gear
lt1swap says ...
Pin 50 - Dk Green/White - VSS - This is a signal generated by the PCM, based on information it receives from the vehicle speed sensor located in the transmission. The PCM takes the sensor signal, and calculates the tire size, gear ratio programmed into it, and makes a 4000 pulse per mile signal. This is useful if you want to use a cruise control box. Some speedometers will use this as an input, others, like Autometer's, will hook directly to one wire of the speed sensor in the trans.
But this sounds more for the gauge itself ...... which it could be ....... but how to diagnose if VSS is getting a signal
