The 1978 Ford F-350 has 4 recalls, the most serious being wheels that may exceed Ford's dimensional specifications, causing tires or tubes to be improperly seated and potentially blow out, leading to loss of vehicle control.
On trucks with C-6 automatic transmissions, a support plate inside the transmission can break and allow fragments to jam the parking pawl, meaning the transmission may not lock into Park when selected or may refuse to come out of Park when you try to drive. There is also a concern on longer-wheelbase trucks built between September 1977 and February 1978 with rear-mounted fuel tanks: dealers may have installed accessory rear step bumpers incorrectly on these vehicles, which leaves the fuel tank without adequate rear-impact protection. The remaining recall is a paperwork correction: weight rating labels and documents overstate the gross axle weight ratings, and new labels will be issued to show the accurate figures.

At a glance
What can fail
Some C-6 automatic transmissions have park actuation cam support plates that may break due to improper heat treatment. Broken fragments can prevent the parking pawl from engaging when shifted to Park or prevent it from disengaging, allowing a parked vehicle to roll if the parking brake isn't set.
