10-Speed Automatic Transmission Assembly for 2021-2025 Ford Bronco, Ranger

A quick look at your own vehicle makes sure the right transmission shows up:

• Confirm your Bronco or Ranger is a 4x4/AWD model with the 2.7L EcoBoost V6 engine (will not fit 2.3L models or 2WD models).
• Check your VIN: The 8th digit must be 'P' for the 2.7L EcoBoost V6 engine.

What the install really takes — plan and budget with confidence:

Special tools this job needs:

• Heavy-duty transmission jack
• Ford-compatible diagnostic scan tool (FDRS)
• Transmission fluid fill pump and adapter
• Alignment dowels/guides

Budget for these consumables at install:

• Motorcraft MERCON ULV (Ultra-Low Viscosity) automatic transmission fluid (Specification WSS-M2C949-A)
• Transmission filter (Part No. HL3Z-7A098-A) and pan gasket
• Transfer case input shaft seal
• Transmission output shaft seal / torque converter seal
• Transmission cooler line flush solvent

What your vehicle’s computers will need after the swap:

What’s involved: Solenoid Body Strategy Programming & TCM Adaptive Relearn

Every Ford 10R60 transmission has a unique 13-digit Solenoid Body Strategy code and a 12-digit Solenoid Body ID printed on a tag on the left side of the case. You MUST program this 13-digit strategy into your vehicle's computer using a Ford dealer scan tool (FDRS) or equivalent. After programming, a TCM Adaptive Learning Relearn must be performed.

Pro tips for a smooth first start-up — hand them to whoever does the install:

• Torque Converter Seating: Must be fully seated onto the transmission pump gears (typically three distinct clicks/drops) before bolting to the engine to prevent cracking the front pump.
• Transfer Case Alignment: Misalignment during mating will cause rapid, premature wear of the output shaft splines and transfer case input splines.
• Solenoid Strategy Tag Preservation: Do not paint over, damage, or remove the Solenoid Body Strategy tag on the left side of the transmission case.
• Fluid Level Check Procedure: No under-hood dipstick. Must be checked via a mini-dipstick on the passenger side of the case with the engine running, vehicle level, and fluid temperature between 195°F and 215°F (90°C to 101°C).
• Adaptive Relearn Drive Cycle: A very specific, multi-step drive cycle must be performed after clearing the adaptive tables with a scan tool.
• Dowel Pin Alignment: Ensure the bellhousing dowel pins are clean and correctly installed in the engine block to prevent misalignment.

Easy to get right once you know them:

• Reusing the Old Solenoid Strategy: Swapping the transmission and driving without programming the new 13-digit Solenoid Body Strategy into the computer.
• Using the Wrong Fluid: Putting Mercon LV or generic multi-vehicle ATF into a 10R60 instead of the required Mercon ULV.
• Misaligning the Transfer Case: Rushing the installation of the transfer case and forcing it to bolt up when misaligned.
• Forcing the Bellhousing Bolts: Bolting the transmission to the engine with the torque converter partially unseated, cracking the pump.
• Not Flushing the Cooler: Failing to professionally hot-flush the cooler lines, which recirculates debris from the old failed unit into the new valve body.
• Assuming 'Learning' Fixes Mechanical Issues: Expecting the adaptive learning strategy to resolve serious mechanical or hydraulic problems.
