VSS and related systems? 
OK, had a problems with a surging/speedo swing that I brought up in the gen maint forum in my 02 B4C. I researched dilligently, and seen the VSS could be the culprit (along with a few other systems/sensors). Ramped/jacked the passenger side and found the VSS loose to the point it was wiggling, and the bolt was easily removed by my 55 year old arthritic fingers. Taking it out, I cleaned it and found it was magnetic. I am guessing this sensor uses the magnetized portion to 'pulse' a signal when the gear inside the tail passes through that field. My question is (as I had posted in that post in gen maint) what are the ramifications of this VSS sensor being loose in the tail where it actually wiggles? After I cleaned it, I reistalled it, and now it is rock solid tight with no movement. Going to drive about 50 miles total today, will see if the speedo swing/surging clears up. I hope this was my recurring problem up to and including the erratic ABS light I had a few weeks ago. BTW, there were no DTC's set on my innova 3110 scan tool and a number of grounds were cleaned, with the PCM also being checked for corroded pins as well (looking for a ground problem or a corroded connection as part of my research/troubleshooting), all looked fine. Only one responded in the gen maint forum, but since I found that VCC loose, I ask in this forum what effect this could have on both the tranny, and the rest of the drivetrain/systems. 
Any tech's out there who can shed some light on this for me? Thread Starter

Looks like that loose VSS was the entire problem! Well, the long (local) trip with multiple stops did not have a single surge/sweeping of the speedo or down/up shifting problem the entire trip. The car was smooth as glass from mild to 'kick-it' driving with none of those annoying problems. Who would have thought that one loose sensor would cause all those symptoms! In a couple days of spirited driving (and no more annoying glitches), I'll go and drop the hypertech tune back in to see what she feels like back on that. Thread Starter

Reloaded tune, all good! Problems didn't show back up, went ahead and put the tune back in. Am hoping this also improves my gas milage seeing as the thing isn't acting all goofy and such. Shame none of the tech's chimed in, I would still like to know how the VSS interties with all those other sensors/systems.
