ATP Parts Z-113 Flexplate Overview

ATP Parts Z-113 is an automatic transmission flexplate built for vehicles that use a flex plate to connect the engine and transmission. It uses high-quality steel, correct bolt-hole spacing, and 168 ring gear teeth to match the original fit and function for selected Chevrolet and GMC applications.

Detailed Description

The flexplate is a critical link between the engine and automatic transmission, transferring rotational movement while allowing for normal expansion as engine speed changes. Over time, repeated flexing can lead to cracks or shearing, and a damaged flexplate must be replaced rather than repaired. ATP Parts Z-113 is built to match the original bolt pattern and ring gear tooth count, helping maintain proper alignment and long-term durability in service.

This part cross-references Pioneer Automotive Industries FRA-111 and Standard Ignition V505 for the same application. It is a direct-fit style replacement for many Chevrolet and GMC models, including Chevrolet Caprice, Impala, Bel Air, El Camino, Malibu, Monte Carlo, Corvette, C10, Blazer, C10 Suburban, C20 Suburban, K20 Suburban, and GMC Jimmy applications listed below.

What It Helps Solve

  • Cracked flexplate from age, heat, or repeated stress
  • Sheared or damaged ring gear teeth affecting starter engagement
  • Torque converter mounting issues caused by worn or distorted bolt holes
  • Noise or vibration traced to a failing automatic transmission flex plate
  • Starting problems related to flexplate damage
