RepairPal has identified the most common problems with the Ford E-150 as reported by actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.Refine by vehicle
This concern is relating to the AOD automatic transmission typically seen mated with the 4.9L 6 cylinder and 5.0L V8 engines. If the Throttle Valve Cable (TV cable) becomes detached from the throttle valve, transmission shifts can be hard or delayed. The grommet that secures the TV cable to the throttle should be replaced. Our technicians note that delaying repair of this concern can lead to internal transmission damage due to the abnormally high internal pressures present when the cable is detached.
This concern related to the 4R100 automatic transmission typically seen mated to the 5.4L V8. If the transmission does not shift correctly out of first gear, a “one-way” clutch inside the transmission may have failed. If the transmission fluid condition is good, and other failures are not found upon transmission tear down, the one-way clutch may be replaced along with the drum and friction plates. Our technicians note this is a major internal transmission repair.
In some cases with higher mileages, the Check Engine Light may come on due to insufficient Exhaust Gas Recirculation system (EGR) flow. For EGR flow concerns, the EGR valve is usually recommended for replacement and the intake manifold is removed to clean the EGR passages in the engine, which have clogged with carbon over time.
If a buzzing noise is coming from the exhaust at different engine speeds and conditions, this is commonly caused by the heat shields on catalytic converters coming loose at points. The buzzing is the metal on metal contact. Installing a large worm clamp around the catalytic converter and heat shield assembly will prevent the noise and secure the shields.
On vehicles equipped with the E4OD (4-speed automatic) transmission, harsh engagement of the automatic transmission when shifting into reverse or drive, and irregular shifting while driving can be caused by failure of the Manual Lever Position (MLP) sensor. Water intrusion can lead to failure of the sensor, which should be replaced with a revised sensor and wiring kit to prevent future failure.
A defective thick film ignition (TFI) module can cause the engine to stall while driving, or the engine may not start. A failed TFI module will require replacement.
A defective key-in warning chime switch can cause the ignition cylinder to bind from run to start and / or start to run movements. The key-in warning chime switch will need to be replaced.
Sludge build up on the throttle plate and/or idle air control valve can cause a poor engine idle, stalling, and/or hesitation – especially when the engine is still cold. The correction is to install a new idle air control valve spacer kit to prevent the sludge build up.
