Common Issues This Part Can Address

• Transmission engagement concerns tied to a worn or mismatched converter
• Incorrect stall characteristics for the vehicle’s drivetrain setup
• Vibration or drivability issues caused by converter wear
• Fitment problems when the bolt circle, pilot, or spline count does not match
• Restoration needs for classic GM automatic transmission builds

Installation Notes and Tips

Confirm the transmission’s spline count, pilot diameter, bolt circle, and mounting style before installation. This B35 uses a slotted hub, drilled mounting points with no threads, and a 3-pad pattern, so matching the original transmission and flexplate specifications is important. For 1981 Chevrolet P20, 1981 GMC G3500, and 1981 Chevrolet P20/P30-style heavy-duty applications, the fitment notes specifically recommend the heavy-duty version with 3 rectangular mounting pads.

TC Remanufacturing supplies this torque converter as a remanufactured drivetrain component for classic GM applications. The B35 is built around the listed OE-style dimensions and mounting specifications to support accurate replacement selection for Chevrolet, GMC, Buick, Oldsmobile, Pontiac, and Cadillac vehicles.
