Went for a cruise with the wife today after washing all of the storage dust off of the car. Car was looking great and driving great and I was moving along on the highway when my speedo shot up a bit then dropped to 0. Got to a friends house 15 minutes from where it happened and pulled the sensor to find this:
That shaft that the gear wheel sits on sheared right off. I have no idea how this possibly could have happened other than the part being defective. I poked around inside as far as I could reach and did not find any sign of the gear wheel where I could reach with my finger.
Needless to say I need a VSS and the proper gear drive. My car is an 86 GT with the 4spd Muncie. Even if you don't have one a point in the right direction would be awesome - I don't know the car well enough to know how fast I'm going by feel or RPMs.
Question: I know logically foreign objects in the transmission case is a bad thing. My car seems to drive fine after this has happened. Does the transmission now need to be pulled with this thing in there?
