Man...the VSS stuff has been a headache - that unit above wouldn't generate enough pulse to feed the ECM.

So...after much research and debate.....the VSS is in......

I found the 4L80E reluctor wheel was just a tad loose over the splines. I hand machined four tapered slots into the wheel, then using four pins and lock-tite, I slid the gear in place and pressed it onto the shaft. I then yanked the VSS out of my 07 silverado to get an idea of how much air gap to set. I then wrapped five runs of tape around the wheel and slid the tail housing back on after I machined out the original speed gear hole to allow a straight on approach with the VSS sensor. Once the housing was back on, I wrapped the VSS in reverse tape, slid it in against the wheel, and filled it with epoxy. After that set, I slid the VSS out, and trimmed it off. I modified the mounting bracket and drilled/threaded the housing to hold the bracket tight. Took it all apart, removed the tape from the wheel - then slid it all back together. With my voltmeter on A/C current - I can spin the tailshaft and get voltage readings to increase the faster I spin it. I think we are good!
