ok so just swapped in the z6 tranny on my y7. thing pull pretty hard now for a stock boosted d16.

anyways we (me and my tuner) have tried 2 vss on it and both of them did not work. we tested each wire and all the wires are fine. do you guy think it has to do with something internally inside the tranny?

 

yeah those sensors dont break often

 

1 way to find out is by putting your car on gear and spin the tires and check with a flahlight
