Hello everyone, I need help deciding whether I'm in deep trouble or okay to continue. I own a 1992 GMC Sierra with a single cab and a short bed. Recently, I had my 700R4 rebuilt and it's been working great. However, my speedometer stopped working, so I replaced the VSS magnetic sensor. It worked fine until one day my speedometer started to jump and then failed altogether. I bought a new sensor, but I installed it a little too loosely, so the speedometer would jump partially. I got under the truck and gave it a couple of good taps and pressed it in with my palm. I let it warm up for a couple of minutes and took it for a test drive. I heard the output shaft, where the VSS is located, start to grind, so I drove it back to my driveway. Upon inspecting the VSS sensor, I saw that I had chipped off a bit of the metal, and my VSS gear wheels seemed to be a little stripped. The fluid that came out seemed fine, although I did see a little black from the plastic of the sensor, and there were definitely little metal sparkles from where the metal of the VSS sensor meets the VSS gear wheel. So, should I be concerned? Should I take it to a shop and have them replace my VSS gear? I assume no, but I wanted to ask any 700R4 experts what they would do. I let most of the fluid drain and scraped out any remaining fluid that seemed contaminated, and the VSS gear wheels didn't seem to be completely distorted. I'm going to put a brand new sensor in today , but only lightly tap it in to make sure I don't end up letting my VSS gear grind against my VSS sensor.
