Does this flexplate fit 2003-2005, 2003-2007, 2004-2007 Ford E-350 Super Duty, Ford Excursion, Ford F-250, Ford F-350?
Those are the verified vehicle applications. Also confirm 6.4L Power Stroke, 5R110, production split, factory equipment, and every ATS application note before ordering.

Why must the transmission match this flexplate?
The crank pattern, converter pattern, starter position, balance, tooth count, and 5R110 must match. A similar-looking flexplate is not proof of compatibility.

Are new flexplate bolts required?
Follow the current ATS and vehicle procedures for bolt replacement, thread preparation, torque sequence, converter spacing, and runout. Do not reuse torque-to-yield hardware where replacement is required.

Installation Instructions

Use the current ATS Diesel instructions and vehicle service information. Verify the exact application, required tools, fasteners, seals, fluids, calibration, torque values, clearances, and startup or relearn procedure. Professional installation is recommended for internal transmission, turbocharger, fuel-system, and driveline work.
