1991 Ford E-250 ProblemsTransmission Fluid Leaks from the Front of the Transmission Bell Housing
This concern relates specifically to the E4OD and 4R100 automatic transmissions. Transmission fluid leaking from the front of the transmission bell housing may also be accompanied with shifting and transmission engagement issues. This is often caused by transmission overheating and is the sign of a significant internal transmission problem. The superficial cause is the failure of the front pump seal of the transmission. The immediate repair is to remove the transmission, replace the front pump and seal, replace all fluid with the transmission filter, and verify proper flow through the transmission fluid lines and cooler. It is also recommended to make sure the vehicle is not pulling a load that is heavier than the gross vehicle weight limits because this can cause the transmission to overheat. Depending on the transmission's mileage, this can also be a good time to consider a complete overhaul or replacement with a remanufactured unit, as often just the pump and seal replacement is a short lived remedy.
This concern relates to vehicles equipped with the E4OD and 4R100 automatic transmissions. Fluid leaks from the rear of the transmission and excessive vibration felt in the vehicle while driving can be caused by a lack of lubrication to the rear of the transmission and rear seal failure. The extension housing (rear portion of transmission) can lose lubrication if the fluid supply hole becomes clogged. This leads to rear seal failure from lack of lubrication, and can cause bearing failure in the extension housing. The extension housing and gasket should be replaced and verify the fluid supply hole is clear of debris.
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.
