What would your mechanic do?

I had a problem with my clutch disk seperating and pushing into the throwout bearing, and wrecking the front half of the trannies bell housing, so my mechanic swapped in a new clutch, and dropped the tranny to swap on the new (used) undamaged bell housing half.

Before the work was done on my car, my speedometer worked perfectly, never any problems at all, and the mechanic test drove the car before the work was done to know it was fine too, but after all the tranny work was done and my mechanic took the car for a test drive, he noticed the speedometer/odometer didn't work, so he checked the speed sensor wiring (fine) Then he checked the fuse (fine), so he took out the speed sensor and found out its broken inside. He opened the sensor up, and the little piece that goes on the end of the long metal rod was broken. I felt it, and it felt really strong, and it was a clean break, not like it was slowly wearing out over time.

What do you guys think about this? I can't exactly accuse anybody, so what do you think? Can a sensor just break like that without wearing out first?

Any advice/suggestions appreciated.

This is just a guess, so I could be wrong. It sounds like the speed sensor was still attached to the bell housing when the front diff was installed, and the teeth on the sensor didn't line up with the teeth on the front diff, so it broke. The manual says to install the sensor after the diff so the two line up with each other. It's an easy mistake to make, I did it the first time I swapped front diffs.

Luckily the solution is easy, too. Just install a new speed sensor. Do you still have the one from the old bell housing?

Thanks for your response, and I BET thats exactly what happened, it makes perfect sense, especially how he was trying to say that there was no visible damage to the outside of the sensor that would have indicated that it was dropped.

The tranny that I used the bell housing off was the mechanics customer's old tranny that broke, so he re-used his speed sensor.

What would my mechanic do? He'd cry like a little girl after I bitched him out
