Vehicles with automatic transmissions have a flex plate. The flex plates connects the engine and transmission. Most flex plates are made of a thick piece of sheet metal with bolt holes for the torque converter and teeth for the starter. The job of a flex plate is to allow for expansion of the torque converter as engine RPM increases. 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:

• Balanced to factory specs
• Fit and function like the original parts
• Restores normal operation

Product Features:

• Casting process closely monitored to ensure uniform density and balance retention
• Eliminates chance of chatter due to hot spots not always removed by resurfacing
• New ring gear ensures positive starter engagement
