Detailed Description

The ATP Parts Z-162 flexplate is a direct replacement-style component for automatic transmission setups that rely on a stamped steel flex plate. It is engineered with 148 teeth and a 12.375-inch outside diameter, along with the specified mounting-hole and diameter dimensions needed for proper fitment. This part cross-references Pioneer Automotive Industries FRA-156 and Standard Ignition V501 for the same application.

Over time, flexplates can crack or shear from repeated expansion and contraction during engine operation. When that happens, the part cannot be repaired and must be replaced. This ATP Parts Z-162 flexplate is built to restore the connection between the engine, torque converter, and starter system on confirmed applications including 1985-1993 Chevrolet S10, 1991-1993 GMC Sonoma, 1985-1990 GMC S15, 1985-1988 Chevrolet S10 Blazer, and 1985-1988 GMC S15 Jimmy.

What This Part Helps Address

• Cracked flexplate material
• Sheared or damaged ring gear teeth
• Starter engagement problems caused by worn teeth
• Torque converter mounting issues from damaged bolt holes
• Noise or drivetrain damage related to a failing flexplate

Installation Notes and Tips

Verify tooth count, outside diameter, and mounting-hole spacing before installation. Inspect the torque converter, starter drive, and related fasteners for wear or damage before replacing the flexplate. Confirm the application matches your vehicle year, make, and model, especially on Chevrolet S10 and GMC Sonoma platforms.
