5R110W Pump 2003-13

If you are rebuilding a 5R110W TorqShift out of a Super Duty, Excursion or E-Series and you have heard the stories of a fresh unit that lost its pump and converter on the road test, this is the kit that addresses one of the main causes. Read this first: this listing is not a complete pump. It is the TransGo 5R1-PMP-ALIGN pump alignment kit, a set of two plastic centering collets and two steel guide pins used to assemble the 5R110W front pump halves dead-center before the bolts are torqued. If you need the pump itself, see the complete pump listings linked below.

Why pump alignment matters in a 5R110W

The 5R110W front pump is a two-piece assembly: the pump body with its converter hub bushing, and the pump cover that carries the stator tube. The converter hub rides in that bushing, and the stator tube sits inside the converter. If the two halves are bolted together even slightly off-center, the bushing and stator tube no longer share a common axis, the converter hub loads one side of the bushing, and the gears run against the plate. TransGo notes that pump half outside diameters can differ by up to .007 in., which is why simply snugging the outer band around the halves does not always center them. The kit centers the pump bushing to the stator tube itself, which is the alignment that actually matters to the converter.

Failures this kit helps prevent

• Pump and converter failure shortly after an overhaul, the complaint TransGo built this tool around
• Inner pump gear welded to the pump plate, which can come from a tight or misaligned bushing generating metal
• A converter hub bushing that seizes to the hub and spins in the pump body
• Front seal leaks from a hub that runs off-center
• Whine that follows engine speed and low line pressure in every gear after a rebuild

Not every burned pump is an alignment problem. TransGo also points to electrical ground faults, oil starvation from a restricted filter or dry start-up, and aggressive line pressure programming. Our 5R110 rebuild wear points guide covers the lubrication and filtration changes Ford made over the years so you can rule those out too.

How to confirm you need it

If you are tearing down a 5R110W that failed after a previous rebuild, look at the pump gears and plate before you order parts. Scoring or welding concentrated on the inner gear and plate points toward a bushing or alignment problem; both gears evenly blackened and blued points toward oil starvation or excess pressure. Either way, if the pump is coming apart, it should go back together with a centering tool. The 5R110 TorqShift service guide walks through the rest of the inspection.

Fitment

TransGo lists the kit for every 5R110W from 2003 on, which covers the 2003-2010 F-250 through F-550 and Excursion with the 6.0L and 6.4L Power Stroke or the gas V8 and V10, plus E-Series vans. Ford changed the pump over the production run, so the kit includes two collets: the white one has a slightly larger inside diameter than the black one, and both share the same outside diameter. You test-fit both on your stator tube and use the one that fits snuggest without force. Not sure what you have? Send us the year and VIN, or browse the 5R110W parts collection.

Install notes

• Do not install the front pump seal until alignment is finished. If it is already in, remove it.
• Check the converter bushing on the converter you will actually run. TransGo gives a bushing-to-hub clearance of .0025 to .0045 in.; replacement bushings sized tighter than that can seize.
• Pre-lube the pump pocket and gears with ATF rather than assembly gel.
• Install the pump-half bolts loose, fit the two guide pins, leave the outer band loose, then slide the chosen collet over the stator tube until its taper seats in the bushing. No force.
• Snug the band, torque pump-to-pump bolts to 23 lb-ft and pump-to-case bolts to 20 lb-ft by hand, not with an impact gun, then install the front seal.
• Fill with Mercon SP ATF.

Pair the tool with a 5R110W pump for 2005-2010 if your pump is past saving, or with a 5R110W overhaul kit for the seals and gaskets the rest of the rebuild needs.

Is this a complete 5R110W pump?

No. It is the TransGo 5R1-PMP-ALIGN alignment kit: a white collet, a black collet and two steel alignment pins used to center the pump halves during assembly. Complete pumps are listed separately.

Which collet do I use?

Test-fit both on your stator tube and use the one that fits snuggest without forcing it. The white collet has a slightly larger inside diameter than the black. Set the other aside.

Does it fit my 2008 F-350 with the 6.4L?

Yes, if the truck has the 5R110W. TransGo lists the kit for all 5R110W units from 2003 on, including the 6.0L and 6.4L Power Stroke trucks.

Is the tool reusable?

Yes, as long as it is never forced. TransGo warns that forcing a collet ruins it and that a damaged collet should not be used.

What else should I replace when the pump is apart?

Check the converter bushing against the hub of the converter you will run, install a new front seal after alignment, and inspect the filter and cooler circuit if the old pump failed from heat or debris.

What fluid does the 5R110W use?

Mercon SP. Pre-lube the pump gears with ATF during assembly instead of assembly gel.
