Transmission Fluid Leaks from the Front of the Transmission Bell Housing on Ford E-250

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.

I was pulling a trailer for about 60 miles today, and started smelling something smokey. I got home 2 miles later and noticed tranny fluid dripping out of tranny between bell housing. It drips/pours out quite a bit when motor is running.
