Detailed Product Description

The ATP Parts Z-104 flexplate is engineered for automatic transmission systems where the flexplate transfers rotational movement between the engine and torque converter while allowing for normal expansion during operation. Over time, repeated flexing can lead to cracks or shearing, and a damaged flexplate should be replaced rather than repaired. This part number, Z-104, is built to match original dimensions and tooth count for proper fit and function.
