8F35 Planetary 2018, new and ready to install. Fits the 8F35. Ships fast from the USA.
This is a new, Ford-branded output planetary carrier, part number JM5Z-7N473-C, for the 8F35 eight-speed transaxle from 2018 production forward. It is the exact carrier Ford calls for in its bulletin on slipping and harsh engagement, so if your Edge, Escape, Bronco Sport, Maverick, Transit Connect, Lincoln Nautilus or Corsair came apart with needle bearing debris in the pan, this is the part that removes the root cause instead of just the symptoms.
The 8F35 builds its eight ratios from a combination of planetary gearsets and clutches. The output carrier sits at the back of the gear train and holds a set of pinion gears, each riding on its own needle bearing, that mesh between a sun gear and the ring gear. Per the listing details, this carrier uses five pinions with 23-tooth gears and an 18-lug interface to the ring gear. Every gear the vehicle drives in passes torque through this assembly, which is why a failure here affects more than one ratio.
Transmission Digest reported a production run of 8F35 carriers whose pinion needle bearings had a hardness problem. Those bearings wear, shed metal and let the pinions move off center. The debris then travels through the clutch packs and valve body, which is how a bearing problem turns into slip and clutch codes.
Pull codes and drop the pan first. Clean ATF with only a light dusting on the magnets points elsewhere, and our guide to the four Ford 8F35 bulletins covers the software shudder fix and the separator plate no-reverse fix that should be ruled out first. Ford bulletin 22-2281 applies to 2019-2021 Transit Connect units built on or before December 20, 2021, but the carrier is the same service part across the 8F35 range. Once the unit is apart, spin each pinion by hand and rock it on its pin; roughness, side play or bluing on the pins confirms the carrier is done.
The listing gives JM5Z-7N473-C for the 8F35 in the 2019-2024 Ford Edge, 2020-2026 Escape, 2021-2025 Bronco Sport, 2022-2025 Maverick, 2019-2023 Transit Connect, 2020-2026 Lincoln Corsair, and the 2019-2023 and 2025-2026 Lincoln Nautilus. The 2018 in the title refers to the transmission's 2018 production start, not a 2018 model year vehicle. Hybrid Escape, Corsair and Maverick models use a different transaxle, and higher-output engines in some of these vehicles use a larger 8-speed, so confirm your transmission is an 8F35 from the door tag or by sending us the year and VIN. Compare the part number on your removed carrier if it is legible. Everything we carry for this unit is on the 8F35 parts page.
Ford's procedure is a full overhaul, not a carrier swap. Replace any clutch frictions with embedded metal, so plan on a master rebuild kit with frictions, steels and filter. Disassemble and clean the valve body and check that the solenoid-controlled valves move freely. If the unit set converter clutch codes, inspect the pump stator to input shaft bushing; a worn bushing means a new pump and converter, otherwise flush the converter. Back-flush the cooler (see our cooler flush guide) so leftover bearing debris does not come back. On reassembly, Transmission Digest warns that the pump drive chain can drop off its gear; Ford tools 307-764 and 307-765 hold it in place, and the converter should go in with the case vertical. Fill with Mercon ULV only, update the PCM software, and expect firm shifts for several days while the adaptive strategy relearns.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. Bulletin 22-2281 lists JM5Z-7N473-C as the output planetary carrier for 8F35 units with worn carrier needle bearings, and that is the part number on this listing.
The 2018 refers to when 8F35 production began. The vehicles listed for this part start with the 2019 Edge, Nautilus and Transit Connect and continue through later Escape, Bronco Sport, Maverick and Corsair models. Send us your year and VIN if you are not sure.
Ford calls for an overhaul seal kit and replacing any frictions with embedded metal. Most rebuilders also replace the steels and filter, and inspect the pump bushing and converter if converter clutch codes were stored.
Motorcraft Mercon ULV. Do not substitute Mercon LV or a multi-vehicle fluid in this transmission.
Yes. Ford reprograms the PCM with the latest software after the overhaul, and the adaptive shift strategy then relearns. Shifts can feel firmer than normal for several days.
