5R110W Overhaul Kit 2003-2010

If your 2003-2010 F-250, F-350, F-450, F-550, Excursion or E-Series with the TorqShift five-speed is leaking from several places, slow to go into gear on a cold morning, or slipping after a lot of towing miles, the transmission is probably ready to come apart. This new 5R110W overhaul kit covers the sealing side of that rebuild. The product photo shows a bagged gasket and seal set, and the listing carries the reference number T136002A, the number most shops use when they order the soft seals and gaskets for this unit.

What the overhaul kit does in a 5R110W

The 5R110W applies its coast, overdrive, intermediate, direct and low/reverse clutches straight from solenoid-controlled pressure, and the computer watches how long each clutch takes to apply. There are no conventional shift valves to soak up a small leak. When a piston seal hardens, a sealing ring on a shaft wears its groove, or a case gasket weeps, the apply gets slower, the computer adds pressure to compensate, and eventually it sets an apply-time code or the clutch slips. This kit supplies the gaskets, piston seals, sealing rings and O-rings that hold each of those circuits closed, so every clutch gets the full pressure it is commanded.

It is a gasket and seal kit, not a complete master kit. Plan on frictions, steels and a filter as separate parts unless your teardown shows the plates are still usable.

Symptoms that call for a reseal on these years

• Fluid on the pan rail, extension housing or bell housing, with the level dropping between checks
• Delayed engagement into Drive or Reverse when cold that improves once the fluid warms
• Flare or slip in several gears after high mileage or heavy towing, not just one shift
• Apply-time codes in the P2700 to P2704 range that return after solenoid work
• Dark fluid with friction material in the pan, which tells you the plates need replacing too

How to confirm before you buy

Rule out the electrical side first. Many 5R110W shift complaints on these trucks come from the solenoid body, and our 5R110 shift solenoid symptoms and testing guide walks through the codes and checks that separate a solenoid fault from a worn clutch. Pull the pan and look at the magnet and filter. If you find heavy friction debris, or if a pressure test shows a circuit that cannot hold, a full reseal with this kit is the right repair. The 5R110 rebuild wear points guide covers what else to inspect once the case is open.

Fitment

This kit is listed for the 5R110W from 2003 through 2010, the years it sat behind the 6.0L and 6.4L Power Stroke and the 5.4L and 6.8L gas engines in Super Duty pickups and cab-chassis, the 2003-2005 Excursion and the E-Series. Ford changed a lot inside this transmission during that run: the front planetary and forward clutch were redesigned for 2005, the pressure switches were dropped from the solenoid body in late 2004, and the external bypass filter began giving way to a sump filter in 2008. Some catalogs list the T136002A number for early 2003-2004 units only, so match the reference on your old kit or send us your year and VIN before ordering and we will confirm it covers your case. You can compare every 5R110W part we carry on the 5R110W TorqShift collection page.

Install notes

• Soak the new piston seals in clean fluid before assembly and lube every sealing ring with assembly gel so it sits in its groove without twisting.
• Air-check each clutch circuit before the case is closed. A circuit that hisses is a seal that will cost you the job later.
• Inspect the low/reverse retaining ring. The original design could walk out of its groove, and an updated ring is the fix.
• Refill with Mercon SP only, then check the level hot with the engine running.
• Replace the filter at the same time. The 5R110W TorqShift filter kit for the 6.0L suits the early bypass-filter trucks, and if the solenoid side tested weak, a 5R110W TCC solenoid is worth fitting while the pan is down.

Does this 5R110W overhaul kit include clutch frictions and steels?

No. The photo shows a bagged gasket and seal set: gaskets, piston seals, sealing rings and O-rings. Frictions, steels and a filter are bought separately, or you can step up to a master rebuild kit if you want everything in one box.

Will it fit my 2008 6.4L Super Duty?

The kit is listed for 2003 through 2010, which includes the 6.4L years. Because some catalogs show the T136002A number for 2003-2004 units only, send us your year and VIN or the number from your old kit and we will confirm the match before it ships.

What fluid does the 5R110W use after a rebuild?

Ford specifies Mercon SP for the TorqShift. Do not top off with Mercon V or a generic multi-vehicle fluid, since the clutch apply timing is calibrated around Mercon SP friction behavior.

Do I need a relearn after resealing the transmission?

Clear any stored codes and drive the truck through all gears with light and moderate throttle so the computer can adapt the new apply times. If the truck has had a solenoid body or a computer replaced, follow the Ford procedure for that part as well.

My truck sets P2700 or P2701. Will new seals fix it?

Only if the cause is a leaking circuit or worn clutch. Those apply-time codes can also come from a bad solenoid or wiring, so test the solenoid body first. If pressure tests and the teardown point to leakage or worn frictions, the reseal is the repair.
