5R110W Reaction Shell 2005-2016, new and ready to install. Fits the 5R110W. Ships fast from the USA.
Under the reaction shell name in our catalog, this listing is actually a banner rebuild kit for the later TorqShift: a TransTec overhaul kit paired with a Raybestos TorqShift HT friction module, part number RHT96-180, for 2005-2016 four-wheel-drive 5R110W transmissions. It is meant for the 4x4 F-250 through F-550 Super Duty or Excursion whose transmission is on the bench because it slips while towing, flares between gears, or comes out with burnt fluid and friction material on the magnet. One box covers the sealing side and the frictions, so the rebuild is not held up waiting on separate orders.
The TorqShift has no bands; five forward gears and reverse come from clutch packs, and five of those clutches are applied directly by their own pressure control solenoid. Sonnax's solenoid chart lists SSPC-A for the coast clutch, SSPC-B for overdrive, SSPC-C for intermediate, SSPC-D for direct and SSPC-E for low/reverse. Because the PCM meters each apply and times it, a leaking piston seal or a glazed friction stretches the apply, and the computer answers with a flare and an apply-time code. The overhaul kit replaces the gaskets, seals, O-rings and other small sealing parts; the Raybestos module replaces the frictions. Together they restore clamping and sealing in every circuit.
Rule out the electronics before buying hard parts. Read the codes, then test the solenoids and wiring as covered in our 5R110 solenoid testing guide; a stuck or weak solenoid can mimic a worn clutch. Check the level hot, pull the pan and look at the debris. Friction material on the magnet, or a clutch circuit that will not hold during an air check, confirms the teardown is needed.
The listing names 2005-2016 5R110W units in four-wheel-drive applications, which matters because the rear sealing parts differ from 2WD. The 2005 model year also marks a hard break inside the unit. Transmission Digest's upgrade history records the forward clutch frictions changing from 90 to 76 teeth that year and the planet gear tooth count going from 18 to 23, so 2003-2004 units need their own frictions. Confirm your build year and drive type, or send us your year and VIN. More TorqShift parts are on the 5R110W parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
A TransTec overhaul kit with gaskets, seals, O-rings and other small sealing parts, plus a Raybestos TorqShift HT friction module, part number RHT96-180.
No. The listing covers 2005-2016. Ford changed the forward clutch from 90-tooth to 76-tooth frictions in 2005, so early units need early-design parts.
The listing specifies 4WD applications. The rear sealing parts differ on 2WD units, so send us your year, VIN and drive type if you are unsure.
Steels are not listed in this kit. Reuse steels that are flat and free of heat discoloration, or replace them separately.
Mercon SP only. After installation, warm the fluid to 130 F on TFT and run Ford's engagement relearn cycles so the PCM adapts to the new clutches.
