E4OD Transmission Cooler 1996-2004, new and ready to install. Fits the E4OD. Ships fast from the USA.
If your Super Duty, Excursion or E-Series van runs hot every time it pulls a trailer up a grade, the cheapest place to buy back some temperature margin is the bottom of the transmission. This kit is a new deep, finned aluminum oil pan with its gasket, listed as the 265-805 style pan for 1996-2004 Ford E4OD and 4R100 transmissions. It is a pan, not a separate radiator-style cooler: it adds fluid volume and surface area under the unit and replaces the thin stamped steel pan Ford installed at the factory.
The E4OD and its 1998-up successor, the 4R100, sit behind the 7.3L Power Stroke, the 5.4L and the 6.8L V10 in trucks that spend their lives working. Heat is what kills them. Every converter clutch slip and every long shift under load turns into fluid temperature, and once the oil is cooked it stops protecting the clutches, the solenoid body and the seals. A deeper pan holds extra fluid, so the same heat load is spread across more oil, and the cast fins give the airflow under the truck more metal to pull heat out of. It is a support part: it slows the rate at which a hard-working unit heats up, and it pays off most for trucks that tow, plow or haul a camper.
The aluminum casting is also far stiffer than a stamped pan, so it does not dish in at the bolt holes the way an over-torqued steel pan does, which is a common source of slow seeps on these units.
A pan cannot fix a restricted cooler circuit, a sticking converter clutch or a failing solenoid pack, so check those first. Read transmission fluid temperature on a scan tool while towing, and measure flow at the cooler return line. If flow is weak, the lines or the radiator cooler are the problem, and our E4OD cooler line replacement guide covers how to inspect and replace them. If temperatures are high with good flow, a deep pan and an auxiliary cooler are the right next steps. For other heat-related failures on this family, see E4OD common problems and fixes.
This pan is listed for 1996-2004 Ford trucks with the E4OD (1996-1997) or the 4R100 (1998-2004). The 4R100 is the updated E4OD and shares its basic case and pan footprint, which is why one pan covers both; our 4R100 vs E4OD comparison explains what did change between them. Before ordering, set your old gasket on a flat surface and compare its shape and bolt pattern to the photo. If you have a 1989-1995 truck, a swapped transmission, or you simply are not sure, send us your year and VIN and we will check it. More parts for this family are on the E4OD and 4R100 collection page.
Pair the pan with a healthy cooler circuit and correct fluid level and it will keep doing its job for the life of the truck.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is a deep, finned aluminum transmission pan with a gasket. It helps control temperature by adding fluid capacity and cooling fins, but it is not a separate auxiliary cooler that plumbs into the cooler lines.
2002 Super Duty trucks use the 4R100, which is inside this pan's 1996-2004 E4OD and 4R100 listing. Compare your old gasket to the photo, or send us your VIN if you want it checked first.
Possibly. A deeper pan moves the floor away from the filter pickup, and some deep pans call for a filter extension or a deep-pan filter. Check the pan's instructions and the pickup height before installing.
Use MERCON V. Expect the deep pan to hold more than the factory pan, so fill gradually and set the final level on the dipstick with the engine running and the fluid hot.
It adds margin, but it cannot fix a blocked cooler line, a weak radiator cooler or a slipping converter clutch. Check cooler flow and temperature first, then add the pan and an auxiliary cooler for heavy towing.
