I was in the middle of fixing of coolant temp dash issue and found this hose ,that look like vacuum/bleed hose, unconnected to anything. Looks like one end goes to the tranny, but couldn't find where the other end would connect to.

Engine is running fine, no code, no nothing. I guess I never realize this until now





Any idea?
Thanks
