6F35 Pump 2013

This is a genuine Ford oil pump assembly for the Gen 2 6F35 six-speed, Ford service number 9L8Z-7A103-J. It is listed for 2013-2019 Ford Escape and Fusion, 2.3L EcoBoost Explorer, and Lincoln MKC and MKZ. Buyers usually need one in one of three cases: the transmission slips or engages slowly once warm, a rebuild turned up scored pump gears or a worn regulator bore, or the old pump was contaminated with metal from a failed clutch pack. The condition is new other: the part is new and unused, but it may not be in its original box.

What the pump does in a 6F35

The 6F35 pump is driven by the torque converter hub and supplies every hydraulic circuit in the transaxle. In the 6F35 family, the pump body also holds the main line pressure regulator valve and the torque converter clutch control valve, so it does more than move fluid. The regulator sets line pressure for the clutch packs, and the TCC valve sends oil to apply and release the converter clutch. On the 6F35, the stator support bushing seals the converter charge and TCC release circuit. Wear in any of these areas reduces pressure to the rest of the transmission.

Symptoms of a worn 6F35 pump

• Slow engagement into Drive or Reverse, especially after the fluid is hot
• Slipping under load, or flares on the 2-3 and 3-4 shifts, because line pressure is too low to hold the packs
• Harsh shifts and overheating if wear at the balance end of the regulator valve drives line pressure high and cuts converter and cooler flow, as Sonnax explains
• TCC shudder or slip, with codes P0741 or P1744, when the stator support bushing or TCC valve bore is worn
• Whine that rises with engine speed, or metal flakes in the filter
• Repeat clutch burn after a rebuild that reused the old pump

How to confirm the pump is the problem

Check fluid level and condition first, then read live line pressure data and any slip codes with a scan tool. Many 6F35 slips start in the valve body and solenoids, not the pump. Our 6F35 transmission problems guide covers how to separate those causes. During a teardown, inspect the pump gears, pocket and regulator bore. Gears Magazine notes that 6F35-family pump gears can show up to .006 in. of clearance in the pocket even on new pumps, and that this is normal. A scored pocket, a galled gear, or a regulator valve that fails a vacuum test means the pump should be replaced.

Fitment

Ford part number 9L8Z-7A103-J supersedes 9L8Z-7A103-B, -D, -G and -H, so it replaces any of those numbers. It is listed for 2013-2019 6F35 applications: Ford Escape and Fusion with 4-cylinder engines and an automatic transmission, the 2016-2019 Explorer with the 2.3L EcoBoost, the Lincoln MKC, and the 2.0L Lincoln MKZ. It does not fit Fusion Hybrid or Energi models, which use a different transaxle, or V6 Explorers, Edges or Tauruses with the 6F50. Earlier Gen 1 units from 2009-2012 had different hydraulics. If your unit is a 2009-2012, or you are not sure, compare the number on your old pump or send us your year and VIN before ordering. Other pump versions and parts are on our 6F35 collection page.

Install notes

• Flush the cooler and lines before you install a new pump behind a failed clutch pack. Debris left in the cooler will go straight back into the pump gears.
• If you install a new stator support bushing, Sonnax notes that the 6F35 bore is tapered from the factory. Use an arbor press so the bushing does not spin.
• Lube the gears with Mercon LV, torque the pump bolts evenly to factory spec, and make sure the converter hub is fully engaged in the pump drive before you bolt the transmission to the engine.
• A pump replacement is usually part of a larger job. Pair it with a 6F35 clutch module if the packs are burned, or a 6F35 solenoid kit if pressure codes were stored.
• Fill with Mercon LV, check the level at operating temperature, then clear adaptives and run the relearn.

Is this a complete pump or just the gears?

It is the genuine Ford oil pump assembly, service number 9L8Z-7A103-J. It replaces 9L8Z-7A103-B, -D, -G and -H.

Does this pump fit my 2010 Escape?

It is listed for 2013-2019 Gen 2 6F35 units. 2009-2012 transmissions are Gen 1 with different hydraulics. Compare the number on your old pump, or send us your year and VIN, and we will confirm fitment before you order.

Will it fit a Fusion Hybrid or a V6 Explorer?

No. Fusion Hybrid and Energi models use a hybrid transaxle, and V6 Explorers use the 6F50. This pump is for the 6F35 in the 4-cylinder Escape, Fusion, 2.3L Explorer, MKC and MKZ.

Can a bad pump cause torque converter clutch codes?

Yes. The 6F35 pump body holds the TCC control valve, and the stator support bushing seals the converter release circuit. Wear in either area can cause TCC slip, along with codes such as P0741 or P1744.

What fluid should I use after installing the pump?

Mercon LV, which Ford specifies for all 6F35 applications. Clear the adaptive tables and run a relearn after the repair.
