Today I dropped the tranny to put my SPEC stage 1 clutch in. I noticed there was a line coming from the firewall to the tranny. It look like some kind of temp sensor. Can anyone tell me what it is and if it is important, thanks.
Basically, it is a line that goes from the transaxle up to the speedometer. There is a little gear on the end of the cable, inside the transaxle, that spins with the trans gears and the speedo converts that into a MPH reading.
