im having trouble getting my vss to give a signal to the pcm. this is causing stalling issues among other things. it is the Dakota Digital cable passthrough SEN-01-4160 paird to a manual trans and transfer case. my engine is a 2003 tahoe 5.3 lm7. pcm is for a 2004 silverado 4.8. My tires are 33/12.5-r15 with a final drive of 4.10. the speedo cable drive gear is 13 tooth whilst the driven gear is either 33 or 32 tooth. i am not sure why the pcm is reading zero speed. the sensor puts out 8000ppm in a sine wave.
