What's wrong, in plain English

Ford is recalling certain F-650 and F-750 trucks equipped with gas engines. A transmission oil cooler line may rub against the air conditioning compressor pulley, and this contact can cause the line to leak transmission fluid. If the leaking fluid comes into contact with hot engine parts, it can create a risk of fire in the engine compartment.

2. Contact a dealer, or call Ford Customer Service at 1-866-436-7332.
3. The inspection and any needed repair of the transmission line is free.
