ATSG 5R110W TorqShift Ford Transmission Rebuild Manual

Rebuilding a 5R110W TorqShift out of a 6.0L or 6.4L Power Stroke Super Duty, an Excursion or an E-Series van without the right book is how a job turns into a comeback. This is the ATSG (Automatic Transmission Service Group) Techtran manual for the Ford 5R110W, the shop reference rebuilders use for teardown, clutch clearances, solenoid data and diagnostic codes on this unit.

What this manual covers for the 5R110W

The TorqShift is unusual enough that general automatic-transmission knowledge only gets you part of the way. It is sold as a five-speed but has six forward ratios: 3.09 first, 2.20 second, 1.54 third, a 1.09 fourth used only in cold mode, 1.00 fifth and 0.71 overdrive. Each clutch except forward has its own variable-force solenoid, some directly proportional and some inversely proportional, so a solenoid in the wrong bore or a misread spec changes how a clutch applies. The manual lays out the full disassembly and reassembly sequence, exploded views of the drums, clutch packs and planetary sets, clutch clearances and selective sizes, valve body and check-ball positions, solenoid resistance and line pressure figures, connector pinouts and the code charts for the electronic controls. The listing notes coverage of both the early 2003-2004 build and the 2005-and-later updates.

Problems this manual helps you diagnose

• Solenoid body faults, shift flare and solenoid electrical codes
• Coast clutch and intermediate clutch wear from towing and heavy duty cycles
• Converter clutch shudder or no lock-up
• Low/reverse snap ring walking out of its groove, causing reverse slip or no reverse
• Cold-mode shift complaints that are really fluid temperature sensor faults
• Harsh engagement after a battery disconnect or reflash, which calls for the adaptive relearn

Before you tear it down

Use the manual's code charts and pressure figures to decide whether the unit needs a full rebuild or just a solenoid, harness or valve body repair. Our 5R110 solenoid symptoms guide sorts electrical faults from mechanical ones, and the 5R110 rebuild wear points guide lists the known failure spots and updates to check once the case is open, including the low/reverse retaining ring and the planetary changes Ford made in 2004 and 2005.

Fitment and coverage

This manual is written for the Ford 5R110W TorqShift used from 2003 to 2010 in the F-250, F-350, F-450 and F-550 Super Duty, the 2003-2005 Excursion and E-Series vans, behind the 6.0L and 6.4L Power Stroke and the 5.4L and 6.8L gas engines. Because Ford changed internal parts across that run, always compare the parts in your hand to the illustrations and check the identification details in the book before ordering hard parts. It is a paperback shop manual, ships from the USA, and covers the transmission itself, not engine or transfer case work. Browse every 5R110W part we carry on our 5R110W parts page.

Using it on the bench

Keep the manual open next to the unit and follow the order of operations; the TorqShift stack has to come apart and go back together in sequence, and selective clearances are where most rebuild mistakes happen. Order your soft parts against the year you are building, such as the 2005 5R110W overhaul kit or the 2008 master rebuild kit, and plan on a TorqShift filter kit at install. Transmission Digest reported Ford's recommendation to replace the oil-to-air cooler on any overhaul rather than back-flushing it, and to change the remote in-line filter at every service. Fill with the fluid Ford lists for your VIN; these units were released on MERCON SP, and Ford later authorized MERCON LV for refill. Finish with the engagement relearn so the rebuilt unit does not go out the door with harsh engagements.

Which years and trucks does the manual cover?

The Ford 5R110W TorqShift from 2003 to 2010 in F-250 through F-550 Super Duty, Excursion and E-Series applications, with the 6.0L and 6.4L Power Stroke and the 5.4L and 6.8L gas engines. It includes the early 2003-2004 build and the 2005-and-later updates.

Is it useful for diagnosis or only for rebuilding?

Both. Along with teardown and reassembly it includes solenoid resistance and line pressure figures, connector pinouts and diagnostic code charts, which help you decide whether the problem is electrical or inside the unit.

Does it list clutch clearances and selective sizes?

Yes. Clutch pack clearances and selective thicknesses are part of the coverage, along with exploded views and valve body check-ball locations.

What else should I order for a rebuild?

An overhaul or master rebuild kit for your year, a filter kit, and any hard parts the teardown shows are worn. Ford also recommends replacing the oil-to-air cooler on an overhaul.

Is this a digital download?

No. It is a printed paperback shop manual that ships from the USA.
