Detailed Description

The ATP Parts Z-131 automatic transmission flexplate is a direct replacement-style component for vehicles with automatic transmissions that require a 164-tooth, weight-added flexplate. It is engineered to match original equipment dimensions, including the bolt-hole pattern and ring gear tooth count, which helps maintain proper connection between the engine, torque converter, and starter system.

The Z-131 is also cross-referenced to Monroe Shocks & Struts 172286 and 182286 for the same application.

Common Problems This Part Addresses

• Cracked flexplate material from repeated expansion and contraction

• Noise or drivability issues caused by a damaged flexplate
• Costly engine or transmission damage from a broken flexplate

Installation Notes

Verify tooth count, outside diameter, and mounting-hole spacing before installation. Confirm the application notes for the specific Jeep model and year, especially where the listing calls out weight-added fitment. Inspect the starter engagement area and torque converter mounting points during service, and replace the flexplate if cracks, distortion, or tooth damage are present.
