5R110W Shift Kit 2003-16, new and ready to install. Fits the 5R110W. Ships fast from the USA.
If your Ford TorqShift has started neutralizing at stops, slipping in reverse or losing it entirely, or setting converter clutch slip codes with a trailer behind it, the root cause is very often the pump-mounted pressure regulator circuit rather than the clutches themselves. This TransGo shift kit is listed for the 5R110W from 2003 through 2016, which takes in the 2003-2010 Super Duty pickups and Excursion with the 6.0L or 6.4L Power Stroke or gas V8/V10, plus the later vans and commercial trucks that kept this transmission after the pickups moved on.
This is not a kit for making shifts feel crisp on a street truck. The 5R110W pump houses the pressure regulator (PR) valve, and as the pump casting distorts with miles that valve starts to stick. TransGo explains the chain of damage: a PR valve stuck in the exhaust position leaves low or no line pressure, the driver revs the engine to see whether the truck is in gear, pump volume surges, and the resulting spike either blows the low/reverse clutch lugs out of the case in Reverse or drops the unit into neutral and damages the low one-way assembly in Drive. Their instructions put runaway reverse pressure around 450 psi with throttle applied.
The current TransGo design answers that with a hardened steel two-piece PR valve built to keep moving in a worn or distorted bore, a pressure control limit bushing with a ball and spring that caps pressure if the EPC solenoid fails mechanically, three converter regulator springs that raise lockup apply pressure, a high-tension low/reverse case snap ring, and an aluminum pressure switch plug with O-ring.
Put a gauge on the line pressure tap before anything comes apart; TransGo calls for a 600 psi gauge because a failing unit can read far past normal. After the kit, their published targets are a 60 psi minimum in Park and Neutral, 100-320 psi in Reverse, and 70-260 psi in Drive and the manual ranges. If reverse is already gone, look at the two low/reverse case lugs first: broken off means a new case, but worn at an angle and still present means the tougher snap ring can save it. Solenoid faults can look like pressure faults, so read our 5R110 shift solenoid symptoms guide and the 5R110 TorqShift service guide before you order.
This listing covers 5R110W transmissions from 2003-2016, and TransGo labels its current kit for 2003-and-later 5R110W units with standard PR bores. Two things change inside that span: Ford redesigned the pump in 2005 (casting RF5C3P instead of the early 3C3P body and RF3C3P stator), and later valve bodies dropped most of the pressure switches. The kit covers both. If you drive a 2011 or newer Super Duty pickup, check the transmission tag, because those trucks use the six-speed 6R140, not this unit. When in doubt, send us your year and VIN, or browse every part in our 5R110W TorqShift collection.
Most shops install this inside a full rebuild, so pair it with a 5R110W master rebuild kit, and if the PR bore is scored beyond saving, a replacement 5R110W pump. Refill with MERCON LV, which Ford authorizes for complete refill of the 5R110W in place of the original MERCON SP, and set the level hot. Our 5R110 rebuild wear points guide lists the other parts worth replacing while it is apart.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only if the case survived. Pull the pan and look at the two low/reverse case lugs. If they are broken off, the case has to be replaced. If they are worn at an angle but still there, the kit's high-tension snap ring is meant to hold the clutch pack and save the case, and the pressure limit parts keep it from happening again.
Its main job is controlling line pressure and raising converter clutch apply pressure, not adding a hard-shift feel. TransGo's post-install pressure targets top out at 260 psi in Drive and 320 psi in Reverse, well below the runaway pressures that break parts.
Yes. If the PC limit bushing measures .768 in., the bore is oversize. You keep the original oversize PR valve and spring and install the kit's new oversize limit bushing and retainer. If that oversize valve still drags, TransGo says to replace the pump.
Not a Super Duty pickup. Ford moved those trucks to the 6R140 six-speed for 2011. This kit is for the 5R110W five-speed only, so check your transmission tag or send us the VIN.
Ford authorizes MERCON LV for complete refill and top-off of the 5R110W, which supersedes the original MERCON SP. Check the level hot after a road test.
