Does that VSS work for what? You don't need a VSS at all to get it running.

You need a VSS to run the speedo if your speedometer is electronic.
As far as the PCM goes, it can't control a TH400 so it doesn't need the VSS sensor input from it.

Having just done this myself, you do not need the VSS to run the swap, but to run the speedo. The electronic sender will give the correct signal for the LS pcm to interpret to the speedo (if you are not still running it to the factory PCM). Both use the same 1000 pulse per mile signal. You will be able to fine tune the speedometer signal through the PCM tuning

Yes just run the pickup and sensor from a 90 SS454 silverado in your TH400 and good to go. I did the same on my th400 lq9 swap. Sensor plug was different so i had to splice that.
