Ford 6R140 Rear Planet with Bearings & Sun Gears (2011-up)
The Ford 6R140 rear planet assembly with bearings and sun gears fits various Ford Super Duty trucks, E-Series vans, and commercial vehicles from 2010/2011 through 2019+, primarily for 6.7L Powerstroke diesel and 6.2L gas engines, with critical variations for 2011-2014 versus 2015-later models requiring specific part identification for compatibility. Key models include F-250, F-350, F-450, F-550 Super Duty, and E-Series vans, but it’s crucial to match the casting numbers/internal components (like separator plates) to your specific transmission’s production date for correct fitment.
Years & Models:
- 2011-2019+ Ford F-Series Super Duty: F-250, F-350, F-450, F-550.
- Ford E-Series Vans: E-250, E-350, E-450.
- Commercial/Fleet Vehicles.
Key Considerations for Fitment:
- Production Dates Matter: Parts differ between early (2011-2014) and late (2015+) transmissions due to internal updates.
- Casting Numbers: Look for casting numbers ending in “EB” (early) or “BA” (late) on the transmission case/parts.
- Internal Components: Match the planet assembly to internal parts like the separator plate (notched vs. non-notched plates) to ensure proper function.
- Engine Type: Typically paired with the 6.7L Powerstroke diesel or 6.2L gas engines.
Recommendation:
Always verify the specific year, engine, and transmission internal components (often identified by casting numbers or photos of the internal parts) against the part being sold, as direct year-to-year swaps aren’t always perfect after 2014.
