speed is off as your VSS is now before the T-case. so you will be going slow, but your VSS is still reading as if your setup is 1:1, not 2.72:1 that it is.

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
