1994 Ford E-350 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.
Electrolysis can cause repeated failures of the heater core and radiator. The diagnosing technician should check for voltage present in the coolant, with the battery disconnected, because electrical current in the coolant causes electrolysis. Corroded or deteriorated parts should be replaced, and the coolant should be flushed. Ground straps can be added to help prevent future corrosion of components.
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.
