Driving to work the other day and got a P056 code which is the transmission speed sensor, and the check engine light came on. I only get the check engine light when I engage the cruise control. I have 2 questions: 1. Does anyone know if this sensor is just for the cruise or is it also used for the speedometer. 2. I'm assuming it is a sensor that mounts to the outside of the transmission somewhere, does anyone no where?
Thanks for any input!

That is the $50 sensor buried $2000 deep in the trans.

Re: P056 code
Unfortunately I just found that out. I should have read other threads before posting.
Think I'll go back to Ford or Chevy. Less problems and cheaper to fix.
