5R110W Clutch Drum 2003-2004, remanufactured and ready to install. Fits the 5R110W. Ships fast from the USA.
The first two years of the TorqShift are the trucks most likely to be on their second or third transmission problem by now: 2003 and 2004 F-250 and F-350 Super Duty pickups, F-450 and F-550 chassis cabs, and the Excursion, many of them behind the 6.0L Power Stroke. When one of those early units slips in certain gears and a teardown shows a drum with scored ring lands or a leaking piston, this remanufactured 5R110W clutch drum for 2003-2004 is the replacement. It is pictured with friction and steel plates and the retaining ring so you can line it up against your old part.
Ford built the 5R110W from the 4R100 but threw out the old hydraulic logic. Each clutch pack other than the forward clutch is fed by its own variable force solenoid, and those solenoids sit in a solenoid body with no shift valves to buffer them. The drum is where that commanded pressure becomes clamping force: oil travels through the sealing rings into the drum, drives the piston into the plates, and locks the pack. Because the computer trusts that the pressure it commands is the pressure the clutch sees, any leak in a drum shows up directly as slip or a long apply time.
The 2003-2004 trucks have a quirk that later years do not. Until late 2004 the solenoid body carried pressure switches, one for each shift solenoid on most units. Sonnax notes the PCM never monitored them, and the rubber boot on the back of a switch can rupture and dump solenoid control pressure. That reads on the road as a clutch slip or shift complaint with no electrical code, which is exactly how a good drum ends up being blamed. Check the switches and solenoids with our 5R110 solenoid testing guide, and confirm line pressure with a gauge, before the transmission comes out.
This drum is listed for 2003-2004 5R110W transmissions. Early production saw running changes, including a rear planet pinion pin update in 2004, so pull your original and compare drum height, spline count, piston style and ring land diameter before installing. If anything does not match, send us the year and VIN and we will check it. We also carry a separate 2003-04 clutch drum and the full range of TorqShift parts on the 5R110W collection page.
If the solenoid body is suspect too, the 5R110W solenoid kit covers the shift solenoids. For every other weak spot to inspect during the same overhaul, see our 5R110 rebuild guide.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2003-2004 5R110W transmissions, which includes the Excursion and the Super Duty trucks of those years. Compare it to your original or send us the VIN to confirm before ordering.
The 2003-2004 solenoid bodies used pressure switches with a rubber boot that can rupture and bleed off control pressure. The truck acts like a clutch is slipping, so check the solenoid body and line pressure first.
Both are for early 5R110W units and are sourced separately. Match the one you buy to the drum you removed by height, splines and piston, and ask us if you are unsure which is correct.
New frictions, steels, seals and sealing rings for that pack, a new filter element, and an upgraded low/reverse retaining ring if the case is apart.
Clearing codes and resetting adaptive shift data with a capable scan tool after the rebuild is recommended, then road test until the transmission reaches full operating temperature.
