Detailed Description

Built for GM automatic transmission applications, the B29DHPF torque converter is specified for vehicles that require a lock-up design with the listed bolt circle, hub style, and pilot dimensions. It is a direct-fit option for many Chevrolet Corvette models, full-size GM trucks and SUVs, and select vans, including 1996-2004 Chevrolet Corvette, 1998-2002 Chevrolet Express 1500 and Express 2500, 1996-2002 GMC Savana 1500 and Savana 2500, and 1998-2000 Chevrolet Tahoe. It also covers earlier GM platforms such as Chevrolet C/K trucks, Blazer, Camaro, Caprice, Impala, El Camino, Monte Carlo, and Oldsmobile Cutlass Calais where the listed converter codes apply.

This part cross-references common OE-style converter code applications for the same GM drivetrain families. The B29DHPF designation is useful when matching the correct lock-up torque converter for a Chevrolet Corvette, GMC Yukon, or Chevrolet Silverado 2500 application.

What This Part Helps Address

• Transmission shudder or slip related to a worn torque converter
• Incorrect lock-up operation in GM automatic transmissions
• Vibration or engagement issues caused by mismatched converter dimensions
• Driveability problems after transmission service or rebuild
• Fitment concerns when replacing a converter by code, spline count, or pilot size

Installation Notes and Tips

Verify the converter code, bolt circle, spline count, pilot diameter, and mounting style against the original unit before installation. Confirm transmission compatibility and inspect the flexplate, pump, and input components for wear before fitting the new converter. Proper fluid fill and careful seating during installation are important for correct engagement and lock-up performance.

Quality Assurance

TC Remanufacturing supplies this torque converter as a remanufactured drivetrain component for GM applications. Match the B29DHPF part number and converter codes to the vehicle’s original specifications to ensure the correct application.
