Detailed Description

This TC Remanufacturing torque converter is built around the listed converter codes and physical dimensions to support proper transmission engagement and torque multiplication in compatible GM and related applications. It is a lock-up design, which helps maintain efficient highway operation in vehicles originally equipped with a lock-up converter.

What It Helps Address

• Shudder or slip from a worn torque converter clutch
• Delayed or inconsistent torque transfer during acceleration
• Converter code mismatch during transmission rebuilds
• Incorrect stall speed after transmission service
• Fitment issues caused by the wrong bolt circle, spline count, or hub style

Installation Notes and Tips

Verify the transmission code, converter code, bolt circle, spline count, pilot diameter, and mounting style before installation. Confirm the vehicle’s original converter code against DCLF, DELF, DF5F, DF6F, DFLF, or DLLF applications, especially on 1980s and 1990s GM trucks, vans, and passenger cars. Proper transmission flush, inspection of the front pump, and checking the flexplate and cooler circuit are recommended during replacement.
