Detailed Description

The ATP Parts Z-338 flexplate is engineered for automatic transmission setups where the flexplate links the engine crankshaft to the torque converter. In Jeep Grand Cherokee and Jeep Wrangler applications, correct tooth count, bolt spacing, and diameter are critical for starter engagement and smooth drivetrain operation. This part number, Z-338, is built to match those specifications and restore proper flexplate function when the original component is cracked, warped, or sheared.

This part cross-references Pioneer Automotive Industries FRA-539 for the same application. It also interchanges with 52117760, 53006328, AA-A319, AM319, and FRA539.

What It Helps Fix

• Cracked flexplate material from repeated expansion and contraction
• Sheared or damaged flexplate sections
• Starter engagement problems caused by worn ring gear teeth
• Noise or vibration from a failing automatic transmission flexplate
• Drivetrain damage caused by continued use of a broken flexplate
