At the risk of incurring the wrath of the "search" promoters I have to ask this question.

I have indeed done the search under Trans Program" and most of the transmissions mentioned are the A4S or A5S560Z.

The transmission in my 530 is an A5S310Z and I was thinking of changing the speed sensor the next time I had the pan off for a service "while I was in there".

According to RealOEM there is no speed sensor listed but instead TWO pulse generators. Am I correct in assuming this is one and the same? and there are two?

Has anyone done this repair? Does the valve body have to come out to make the switch?

Even though I've done fluid and filter changes on both cars I'm NOT a transmission guy and don't want to get in over my head.

Thanks for the info,
DJ
