5R110W Pump 2005-2010, remanufactured and ready to install. Fits the 5R110W. Ships fast from the USA.
A 2005-2010 Super Duty with the 5R110W TorqShift that is slow to pick up Drive or Reverse on a cold morning, slips in every gear once it is hot, or whines in step with engine speed is usually telling you the front pump can no longer hold line pressure. This remanufactured 5R110W pump is listed for the 2005-2010 years, which is the window where Ford ran its second- and third-generation pump designs behind the 6.0L and 6.4L Power Stroke and the gas V8 and V10.
The pump is driven by the converter hub and produces every bit of pressure the transmission uses, but on this unit it is more than a pump. Sonnax lists five valves housed in the 5R110W pump: the main pressure regulator, the converter pressure limit valve, the converter clutch control valve, the thermal cooler bypass valve and the converter anti-drainback valve. That means a worn pump body affects line pressure, lockup, cooler flow and lube at the same time. Ford redesigned the pump for 2005 partly because of low pressure on the first design, updating the pressure regulator valve and casting the cover from a harder aluminum-silicon-copper alloy. From 2008, as trucks dropped the external bypass cooler filter, a third generation added a notch in one worm track of the cover to keep lube flowing at very low temperatures.
Put a pressure gauge on the line port and compare idle and stall readings to spec before you condemn the pump. The 5R110W shifts every clutch with its own variable force solenoid, so a weak pressure control solenoid can mimic a tired pump; our 5R110 shift solenoid guide covers how to rule that out. If pressure is low in every range and the solenoids test good, the pump's pressure regulator bore is the prime suspect. The 5R110 rebuild wear points guide explains that bore wear and the bushing checks.
This pump is listed for 2005-2010 5R110W units in the F-250 through F-550 Super Duty, plus the 2005 Excursion and E-Series applications built with this transmission. The important split inside this range is the cooler filtration. Ford's two service pumps are 9C3Z-7A103A for trucks that still have the external filter-bypass system and 9C3Z-7A103B for trucks without it, and Transmission Digest warns that the non-bypass pump is not to be used on bypass models. The changeover started in 2008, so a 2008-2010 truck can be either. Look under the truck: if the remote spin-on cooler filter and bypass plumbing are still there, you need the bypass version. A Gen. 3 non-bypass pump carries the number 9C3P-7A103-AC near the bolt circle. Compare that against your old pump, or send us your year and VIN and we will confirm the match. Every part for this unit is on our 5R110 TorqShift parts page.

It is listed for 2005-2010. The 2003-2004 trucks used the first-generation pump, which Ford redesigned for 2005. Ford's bypass service pump 9C3Z-7A103A is noted as retrofitting back to 2003, but match your casting numbers or send your VIN before you order for an early truck.
Check for the external remote cooler filter and bypass plumbing. If it is there, the truck needs the bypass-style pump. If the truck was built without it, it takes the non-bypass Gen. 3 pump, identified by 9C3P-7A103-AC near the bolt circle.
A pump problem shows up in every range: late engagement in Drive and Reverse, slipping in all gears, low gauge pressure and a whine that follows RPM. A single bad solenoid usually affects one shift or one clutch.
Mercon SP, or Mercon LV, which Ford authorizes for complete refill and top-off on the 5R110W. Do not use Mercon or Mercon V.
A front seal at minimum, and inspect the converter hub. If low pressure has been present for a while, check the clutch packs and the solenoid body, because they take damage from running on low pressure.
