Pair of C4 Transmission Cooling Lines for 1971-1973 Mustangs with 6-Cylinder Engines.These lines connect the transmission to the radiator and transfer fluid to cool the transmission.
As with most steel parts, transmission lines tend to rust due to the elements. The transmission cooling lines run under the car so they are subject to the weather.
You can purchase these lines in original steel or stainless steel which stands up to rust better than the original steel lines. Includes correct fittings and flared ends.
