Today I flushed the brake lines and clutch on my son's 2013 JCW Paceman. While opening the valve on the slave cylinder to flush the clutch, I noticed an electrical connection on the front of the transmission. NewTIS refers to it as the 'zero-gear sensor.' I didn't get any hits on NAM. What does it do and how important is it? Trying to figure out if I need to replace it.

 

If Im not mistaking, this could be the auto start stop option. it is only in europe though!

 

Thank you. If that’s the case, I’m not concerned. Just wanted to make sure it wasn’t something removed by the previous owner.
