Question type: Maintenance & Repair

How does it get in my water

2 Answers


There's a transmission fluid cooler in the radiator. Transmission fluid flows from the transmission, through metal lines that screw into the radiator tank. Usually on the passenger's side of the radiator on GMs. If the cooler inside rusts out you'll get transmission fluid in the cooling system. You'll have to replace the radiator, flush the engine cooling system, and flush the transmission. HTH. -Jim

Don't mess around and put off this repair as your transmission can be ruined if coolant gets in it.
