Summary
The Ford C Series has 3 recalls covering 1972 and 1974-1978 model years, with the most serious affecting 1974 vehicles equipped with MT-650 automatic transmissions, where nylon particle contamination in the governor assembly can cause the transmission to disintegrate, shift improperly, or downshift without warning.
The 1978 model year on C600, C700, C800, and CT800 variants has a seven-blade aluminum cooling fan that can develop fatigue cracks and shed a blade, potentially damaging components in the engine compartment and injuring anyone nearby when the tilt cab is raised. A similar fan blade issue affects 1972 models equipped with 361, 389, or 391 cubic inch FT gasoline engines paired with Allison AT-540 automatic transmissions, where metal fatigue can cause a blade to separate without warning and strike underhood components or anyone working near the vehicle.
