Detailed Description

This TC Remanufacturing torque converter, part number DA31-20, is specified for 1998-2004 Nissan Frontier, 2000-2003 Nissan Xterra, 2000-2001 INFINITI QX4, and 2000-2001 Nissan Pathfinder applications. The lock-up design helps maintain efficient power transfer in supported automatic transmissions, while the low stall setup and OE-style dimensions support proper engagement and drivability. If you are replacing a worn torque converter in a Nissan Frontier, Nissan Xterra, or Pathfinder, DA31-20 provides the fitment and configuration details needed for the correct application.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Replacement Reasons

• Shudder or vibration during lock-up operation
• Delayed or inconsistent torque transfer
• Transmission slip related to converter wear
• Noise or rough engagement from a failing converter
• Incorrect replacement after transmission service on Nissan Frontier, Xterra, Pathfinder, or INFINITI QX4 models

Installation Notes and Tips

Verify converter codes J1, J2, T1, or T2 before installation. Confirm the 20-spline interface, 9.765-inch bolt circle, 4-pad round mounting pattern, 10mm x 1.0 threads, 0.785-inch pilot diameter, and milled flats hub match the original unit. Always inspect the transmission, cooler circuit, and flexplate condition before installing a replacement torque converter.

Quality Assurance

TC Remanufacturing torque converters are built to match application-specific transmission requirements and dimensional specifications for supported Nissan and INFINITI vehicles. Part number DA31-20 is identified for direct application matching in the listed fitments.
