Good info. and thanks for the time to put it together. I could not find in the vehicross shop manual how to diagnose it other than how to replace it. It could very well be a bad sensor but wanted to get some general feedback to see if the speed sensors was one of the problem areas of the VX which it sounds like it is not. I do have access to a "rack" to test the car so it just a matter of getting the time to do it. I have not checked out Tone's tech manual yet and will soon. Tone, Lisa(VX Crazy) and I have been working with each other on transplanting her rear diff. out of her RIP VX into mine as well. So I need to add that to my "VX to do" list. Again, I appreciate it.
