ATP Parts Z-487 Automatic Transmission Flexplate

Automatic Transmission Flexplate Overview

ATP Parts Z-487 is an automatic transmission flexplate built for vehicles with the correct 135-tooth ring gear and 12-to-14 pitch flywheel pattern. It connects the engine and transmission, providing the interface the torque converter needs while the engine runs.

Fits 2003 Ford Windstar, N/A. Fits 2004-2007 Ford Freestar, N/A. Fits 2004-2007 Mercury Monterey, N/A.

• High-quality steel construction for strength and durability.
• Correct bolt hole spacing and ring gear teeth to match the original part.
• 135-tooth design for applications that require this exact configuration.
• Built for automatic transmission use where the flexplate links the engine and torque converter.

What This Flexplate Does

The flexplate transfers rotational movement between the engine and automatic transmission while allowing the torque converter to expand as engine speed changes. Over time, repeated flexing can lead to cracks or shearing, and a damaged flexplate can cause serious drivetrain damage. ATP Parts Z-487 is made to replace a worn or broken unit with the correct tooth count and fitment details for Ford Windstar, Ford Freestar, and Mercury Monterey applications.

• Cracked or fractured flexplate replacement.
• Starter engagement issues caused by worn ring gear teeth.
• Noise or vibration from a damaged flexplate.
• Drivetrain damage linked to a failing engine-to-transmission connection.

Installation Notes and Tips

Verify tooth count, outside diameter, and pitch flywheel specification before installation. This part cross-references Pioneer Automotive Industries FRA-494 and AA-F256 for the same application. Confirm the transmission and engine combination matches the listed fitment before replacing the flexplate.

Quality Assurance

ATP Parts manufactures this flexplate from high-quality steel with original-style bolt hole spacing and ring gear teeth for long service life and durability. Part number Z-487 is engineered as a direct replacement for the specified automatic transmission applications.
