First post on the forums! WOOT WOOT!

I have a "check engine soon" light on a (((2000 Q45))). When I checked the codes that were setting this off, I got code p0720.

The FSM says that this code is in relation to the revolution sensor.

The manual is vague on how to get to the part.

I want to know:
1. Any parts # associated with the revolution sensor
2. Do you have to lower the A/T assembly to get to the revolution sensor?
