ATSG 5R110W TorqShift Ford Transmission Rebuild Manual

This is the ATSG technical manual for the Ford 5R110W TorqShift, the five-speed (functionally six with the cold-mode ratio) automatic Ford ran behind the 6.0L and 6.4L Power Stroke diesels and the 5.4L/6.8L gas engines in the 2003-2010 F-250, F-350, F-450 and F-550 Super Duty, the 2003-2005 Excursion, and the E-Series vans. If you are opening one of these units, this is the book you want laid out on the bench next to it.

The 5R110W has its own set of habits. The direct clutch and the intermediate clutches cook when the truck has been worked hard or towed hot, the pressure control and TCC solenoids inside the harness-mounted solenoid body drift and set codes, and the valve body bores wear until line and converter-clutch control go away. Guessing at clutch clearances or solenoid values on this transmission is how a rebuild comes back. The manual gives you the real numbers: complete disassembly and reassembly order, exploded views of the drums, clutch and planetary stack, clutch pack clearances and selective thicknesses, valve body and check-ball locations, solenoid resistance and line pressure specs, connector pinouts, and the diagnostic trouble code charts for the electronic controls.

ATSG (Automatic Transmission Service Group) writes these for people who actually rebuild transmissions, so the procedures match what you hit on the bench rather than a generic overview. It covers both the early 2003-2004 configuration and the later 2005-and-up updates, which matters because Ford changed valve body and solenoid details across the run. Standard paperback shop-manual format, ships from the USA. Pair it with a master overhaul kit, the correct solenoid body and a valve body that has been gone through and you have what you need to put a 5R110W back together right the first time.
