5R110W Overhaul Kit 2003-2014

The TorqShift five-speed stayed in production long after Ford's pickups moved on, so the people shopping for a 2003-2014 5R110W overhaul kit range from Super Duty diesel owners to fleet managers with an E-350 cutaway or a V10 motorhome that has started to leak, flare between gears or engage slowly on cold starts. This new kit is the sealing package for that rebuild. The product photo shows a sealed Precision International bag, the type of gasket and seal set rebuilders order alongside a separate friction and steel package.

How the overhaul kit works in the 5R110W

Each clutch in this transmission is fed by its own solenoid-controlled circuit, and the computer judges clutch health by how quickly each apply happens. That makes the 5R110W unforgiving of leakage. A piston lip that has taken a set, a Teflon ring that no longer seals against a worn bore, or a pan or case gasket that seeps all slow the apply, and the computer can only add so much pressure before it flags a fault or lets a clutch slip. An overhaul kit puts new gaskets, piston seals, sealing rings and O-rings into every circuit so the hydraulics behave like a fresh unit again.

Symptoms that point here

• Leaks at the pan, front pump seal area or rear housing, with fluid level falling between services
• Slow or harsh engagement into Drive or Reverse first thing in the morning
• Slip or flare under load in more than one gear, often worst when hot or towing
• Apply-time codes such as P2700 or P2701 that keep returning after electrical repairs
• On 2009 and later E-Series vans, coast clutch trouble, where Ford issued guidance on coast clutch cylinder weld failures

How to confirm the diagnosis

Before buying any soft parts, check the solenoid body and wiring, because a weak solenoid can mimic a leaking clutch. Our 5R110 TorqShift service guide covers the fluid check, pan inspection and code reading in order. Friction material on the magnet, varnished fluid, or a circuit that will not hold during an air check confirms the rebuild. Then use the 5R110 rebuild wear points guide to inspect the hard parts that commonly fail with the soft parts.

Fitment

The listing covers 5R110W units built from 2003 through 2014. From 2003 to 2010 that means Super Duty F-250 through F-550 trucks with the 6.0L or 6.4L Power Stroke or the 5.4L and 6.8L gas engines, plus the Excursion through 2005. When the Super Duty switched to the six-speed 6R140 for the 2011 model year, the 5R110W kept going in E-Series vans and cutaways and in V10 stripped chassis, which is where the 2011-2014 coverage applies. Internal changes over those years are significant, including the 2005 front planetary redesign, the 2008 move from the external bypass filter to a sump filter, and the late-2008 low one-way clutch that became part of the rear planet. Gaskets and seals carry across most of these, but confirm by matching the number on your old kit or by sending us the year and VIN. Browse the full range on the 5R110W TorqShift parts page.

Install notes

• Lay out the kit against your old parts before installing, and keep the different sealing rings sorted by shaft.
• Pre-soak lip seals in fluid and use assembly gel, never grease that will not dissolve, on the sealing rings.
• Air-check each clutch before closing the case, and check the coast clutch cylinder welds on E-Series units.
• Fill with Mercon SP and set the level hot, engine running, in Park.
• Fit a new filter during the job. The 5R110W filter kit for the 6.0L Super Duty covers early trucks, and if tests showed a weak line pressure command, the 5R110W pressure control solenoid is a sensible add while the valve body is accessible.

Why does this kit run to 2014 when the Super Duty pickups changed in 2011?

Ford moved the F-250 through F-550 to the 6R140 six-speed for 2011, but the 5R110W stayed in E-Series vans and cutaways and in V10 stripped chassis. The 2011-2014 years on this listing apply to those vehicles.

What comes in the kit?

It is a gasket and seal overhaul set: gaskets, piston seals, sealing rings and O-rings. It does not include frictions, steels or a filter, so buy those separately if your teardown shows they are worn.

Should I replace the coast clutch cylinder on my E-Series while it is apart?

Inspect it. Ford addressed coast clutch cylinder weld failures on 2009-2015 E-Series vans with the TorqShift and calls for replacing only the cylinder in most cases. If the welds are cracked or separating, replace it during this rebuild.

What fluid should I use?

Mercon SP is the specified fluid for the 5R110W. Fill to the hot mark with the engine running and recheck after the first drive.

How do I know it fits my unit?

Compare the number on your old kit, or send us your year and VIN. Gaskets and seals are shared across most of the 2003-2014 production, but the internal changes over those years mean a quick confirmation is worth it.
