  • 12.5-inch converter diameter for optimal torque capacity
  • Lock-up converter type with carbon woven friction single clutch
  • Heavy-duty construction suitable for demanding applications
  • Slotted/stepped hub type with 36 spline count
  • Billet lid mounting type with 10mm x 1.5 mounting thread size
  • Stall speed range between 1400-1600 RPM
  • Compatible bolt circle diameter of 11.000 inches
  • Pilot diameter of 1.701 inches and pilot length of 1.000 inch

Technical Details and Performance Features

The HDB85JMBX torque converter from TC Remanufacturing features a lock-up design that enhances transmission efficiency by reducing slippage during highway driving. Its carbon woven friction single clutch provides reliable engagement and heat resistance, which is critical for heavy-duty use. The 12.5-inch diameter and 36 spline count ensure compatibility with a variety of GM automatic transmissions, while the billet lid mounting type and slotted/stepped hub design contribute to secure installation and durability under load. The stall speed of 1400-1600 RPM is optimized for smooth acceleration and power delivery in vehicles such as the GMC Sierra 2500 HD and Hummer H2.

Compatible Vehicles and Applications

This torque converter is compatible with multiple GM makes and models, including:

  • Cadillac Escalade, Escalade ESV, Escalade EXT, STS
  • Chevrolet Avalanche, Camaro, Caprice, Express 3500, G8, Silverado 1500, 2500 HD, 3500 HD, Suburban 1500, 2500, 3500 HD, Tahoe
  • GMC Sierra 1500, 1500 Limited, 2500 HD, 3500 HD, Yukon, Yukon XL, Yukon XL 1500, Yukon XL 2500, Savana 2500, 3500
  • Hummer H2
  • Pontiac G8, SS

Common Issues Addressed by This Torque Converter

  • Transmission slipping or delayed engagement
  • Overheating due to inefficient torque transfer
  • Reduced fuel efficiency from non-lock-up converters
  • Excessive shudder or vibration during acceleration
  • Premature wear of transmission components from inadequate clutch friction

Installation Notes and Tips

Ensure the torque converter is properly seated on the transmission input shaft and fully engaged with the pump before installation. Verify the 11.000-inch bolt circle matches the flexplate and use the specified 10mm x 1.5 mounting threads for secure attachment. The billet lid mounting type requires careful torque application to avoid distortion. It is recommended to inspect the transmission fluid and replace it if contaminated during installation.
