The lock-up design, 12-inch diameter, 30-spline hub, and 3-pad mounting pattern make it a fitment-specific replacement for vehicles that require the matching converter code and stall characteristics.

What This Part Helps Address

• Transmission shudder or poor lock-up operation from a worn converter
• Incorrect stall speed affecting drivability and launch feel
• Vibration or engagement issues tied to converter wear
• Fitment problems when the converter code does not match the transmission
• Loss of smooth power transfer between engine and automatic transmission

Installation Notes and Tips

Verify the converter code on the original unit before installation and match it to BB, BB4C, BB4D, BB8D, or BB8F as listed. Confirm the 10.750 bolt circle, 1.703 pilot diameter, 30-spline count, and 3-pad mounting style against the transmission and flexplate setup. Because fitment varies by year and model, use the exact vehicle listing for your Chevrolet, GMC, Pontiac, Buick, Oldsmobile, or Cadillac application before ordering.
