Default ABS Engaging when coming to a stop

This problem seems to be getting worse. There's no light on the dash, it just does that little fart thing and takes some of my brake power away. What is the easiest way to check my wheel speed sensors?

I think it might have to do with my manual swap but I can't figure out how to fix it. My speedo is reading correctly but I'm afraid something is out of whack on the "PCM OUtput Calibration" or something like that. I swapped from a 4l60e to a NV4500.

A ABS scanner would show each wheel speed and if one sensor dropped out to zero while the other 3 were still at say 3-5mph it would engage the ABS.

Measure the voltage difference between the front sensors using a multimeter. Plenty of good info on google about how to do it

I will. But today I noticed my speedo dropping off while I was rolling at low speed. Does it act as the rear vss also?
