ATP – Automatic Transmission Flex Plate (Part No.Z-124)

Automatic Transmission Flex Plate

from

$102.99
Vehicles with automatic transmissions have a flex plate. The flex plates connects the engine and transmission.

The constant expansion and contraction of a flex plate over time can result cracks and/or shearing of the flex plate. A damaged flex plate can create serious (expensive) damage. Broken flex plates can not be repaired, they must be replaced. ATP flex plates are made of high quality steel and contain the correct bolt hole spacing and ring gear teeth just like the original part to ensure long life and durability

Product Features:
