Leaking Transmission Cooling Lines on 2006 STS

Asked by Jul 22, 2015 at 11:34 AM about the 2006 Cadillac STS V6

Question type: Maintenance & Repair

My transmission cooling lines are leaking at the clamps where the rubber hose attaches
to the metal one coming from the radiator. Can the clamps be changed or just the rubber
hose and how do you check the fluid in this car?

I'd try to tighten the clamps first. If that doesn't stop the leak I'd install new clamps. But if there is enough slack, cut the lines back an inch and reinstall as the hose might be the issue in that area.
