Pioneer Automotive Automatic Transmission Flexplate Steel

Pioneer Automotive steel automatic transmission flexplates, also called flex plates or automatic transmission flywheels, are replacement parts built to restore OEM-level performance. The flexplate connects the engine crankshaft to the torque converter. It also carries the ring gear teeth that the starter engages.

Key Features:

• Made from high-grade steel for strength and long service life
• Built to the original dimensions, with bolt-hole spacing and ring-gear teeth matching the OE part
• Automated welding process for consistent strength
• Precision balanced to factory specifications for smooth operation
• Quality tested
• SFI-certified options available in the line

A flexplate flexes as the torque converter expands with rising engine RPM. Over time this repeated movement can cause cracks or shearing. A damaged flexplate cannot be repaired and must be replaced, because it can cause serious and expensive damage if left in service.

Pioneer Automotive Industries has made automotive components since 1946. This line gives a dependable, OE-style replacement for restoring proper drivetrain operation.
