Detailed Description

TC Remanufacturing DA48SS is an automatic transmission torque converter for Nissan Frontier, Nissan Xterra, Nissan Pathfinder, INFINITI QX4, INFINITI G35, and INFINITI I35 applications that require the listed lock-up configuration and physical dimensions. The medium stall setup supports drivability characteristics matched to the original transmission calibration, while the 4-pad mounting design, 20-spline count, and flats hub help ensure the correct interface with the transmission and flexplate assembly. Use the part number DA48SS and the converter codes to verify application match before installation.

This part cross-references 1A Auto (e.g., 172286, 182286) for the same application.

What It Is Used For

• Restoring proper torque transfer in a slipping or worn converter
• Addressing shudder or inconsistent lock-up operation
• Replacing a converter with damaged hub, pilot, or mounting surfaces
• Correcting drivability concerns tied to converter code or stall mismatch
• Supporting transmission rebuilds on listed Nissan and INFINITI models

Installation Notes and Tips

Confirm the converter code, bolt circle, spline count, pilot dimensions, and mounting style against the original unit before installation. Verify transmission compatibility for the specific vehicle and model year, especially on 1997-2004 Nissan Pathfinder, 1997-2000 INFINITI QX4, 1999-2004 Nissan Frontier, 2000-2004 Nissan Xterra, and 2003 INFINITI G35 and I35 applications. Inspect the transmission pump, flexplate, and cooler circuit during replacement to help prevent repeat failure.

Quality Assurance

TC Remanufacturing supplies remanufactured drivetrain components for transmission service applications. DA48SS is built to the listed specifications for fitment verification against the original converter code and dimensions.
