Even on my 4wd vehicles, the Vss has always been on the t-case and usually a switched contact in the PCM to recognize it is in low range to adjust shift points while still keeping the speedo correct since it is on the final output, not before the lower gearing the t-case provides

The speedo and shifting is spot on in 2wd and 4 high. It is about 3x off (30=90) in 4 low. It acts as if the vss is still in the t-case. There are no wires on the t-case or t-case shifter at all. The speed of the trans output should not be affected by the t-case being in low, but somehow it is. Advanced adapters sells this kit
http://www.advanceadapters.com/produ...-output-shaft/. I ordered the clamp on reluctor ring from them. I already had the VSS. This makes no sense at all. There is no way that the pcm knows the t-case is in low gear. It must be psychic...
