5R110W Clutch Module 2003-2004, new and ready to install. Fits the 5R110W. Ships fast from the USA.
The first two years of the 5R110W TorqShift, behind the 2003-2004 6.0L Power Stroke in Super Duty pickups and the Excursion, are now old enough that many are on their second or third trip around the odometer. If yours slips when hot, bangs into gear late, or flares between shifts with a trailer behind it, the friction plates are a prime suspect. This listing is a new 5R110W clutch module for 2003-2004 units: a set of frictions and steels, shown in the photo, for rebuilding the worn packs in an early-design transmission.
Ford built the 5R110W as a redesign of the 4R100, and it introduced the design in model year 2003. It uses six clutch packs to get five ranges and six forward ratios: the overdrive clutch is applied in a cold-mode 4th and in 2nd to split the gears. Each friction plate is lined and splined to one part of the gear train, each steel to another, and hydraulic pressure from the solenoid body squeezes them together. Every clutch except the forward clutch has its own dedicated solenoid. Thin or glazed frictions mean the pack cannot lock quickly under the torque of a diesel, and the slip shows up first under load.
The early years are a different animal from 2005-up. Transmission Digest notes that 2003-2004 units use 90-tooth forward clutch frictions, which Ford changed to 76 teeth in 2005 along with the front planetary and sun gear. That is why a clutch set for these years is a separate part number, not a universal fit.
Early units carried pressure switches in the solenoid body, but Sonnax notes the computer on these trucks was never programmed to monitor them, so a slipping clutch and a sticking solenoid can look identical from the driver's seat. Check fluid level and smell, pull the pan and look for friction debris, then scan for solenoid electrical codes and compare commanded gear to actual ratio. Our 5R110 shift solenoid symptoms guide walks through those tests. If the pan is full of friction material, the 5R110 rebuild wear points guide covers the other early-unit parts to inspect while it is apart.
This module is listed for 2003-2004 5R110W transmissions in Ford F-250, F-350, F-450 and F-550 Super Duty trucks and the Excursion, including the 6.0L diesel and the 5.4L and 6.8L gas engines. Transmission Digest says the 2003 rear planet was updated by 2004 and should not be reused, and other early parts changed mid-run, so match your old frictions by tooth count and plate count against this set before ordering. If you are unsure, send us your year and VIN and we will confirm the fit. A 2005 or later unit needs the 2005 5R110W clutch module instead; the rest of our early-unit parts are on the 5R110W parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Ford changed the forward clutch frictions from 90 teeth to 76 teeth in 2005, along with the front planetary. For 2005 units use our 2005 clutch module.
Hot slip is a classic sign of worn frictions or worn piston seals, but check the fluid level and solenoid codes first. If the pan shows friction material, plan on clutches and seals together.
Mercon SP. Ford says it is not interchangeable with Mercon or Mercon V, so do not top off or refill with anything else.
Only if they are flat and free of heat bluing and hot spots. This set includes steels, so most rebuilders replace them along with the frictions.
Piston seals and gaskets, the pan filter, the remote canister filter element and the cooler. Also check the rear planet, since Transmission Digest says the original 2003 version should not be reused.
