Product Details

The ATP Parts Z-189 flexplate is engineered for automatic transmission applications where the flexplate transfers rotational movement between the engine and torque converter while also providing starter ring gear teeth. Over time, repeated expansion and contraction can lead to cracking or shearing, and a damaged flexplate should be replaced rather than repaired. This replacement flexplate follows original-style dimensions and tooth count to support proper alignment in Ford Ranger, Ford Aerostar, and Mazda B3000 applications.

What It Helps Address

• Cracked flexplate from fatigue or repeated stress
• Sheared or damaged ring gear teeth
• Starter engagement problems caused by worn teeth
• Torque converter mounting issues from incorrect bolt spacing
• Noise or drivability concerns linked to a failing flexplate

Installation Notes

Verify tooth count, outside diameter, and mounting-hole spacing before installation. Confirm automatic transmission application and match the vehicle’s original flexplate specifications, including the 135-tooth design and 11.3 in. outer diameter. Inspect the starter, torque converter, and related drivetrain components for wear before installing the replacement flexplate.

Quality Assurance

ATP Parts manufactures this flexplate in high-quality steel with OE-style dimensions for consistent fit and long service life. The Z-189 is built to match the original bolt pattern and ring gear tooth layout for the listed Ford Ranger, Ford Aerostar, and Mazda B3000 applications.
