Detailed Description

TC Remanufacturing TO86 is engineered for Nissan automatic transmissions that require a lock-up torque converter with the listed OE-style dimensions and mounting pattern. The 11.200-inch diameter, 6-pad mounting type, 9.062 bolt circle, and 20-spline configuration are important reference points when matching the correct replacement. This part number, TO86, is listed for 2004-2009 Nissan Quest, 2005-2006 Nissan Altima, and 2004-2006 Nissan Maxima applications.

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

What It Is Used For

• Replacing a worn or failing automatic transmission torque converter
• Restoring lock-up operation in the transmission
• Addressing shudder, slip, or poor coupling during acceleration and cruise
• Correcting fitment issues tied to converter diameter, spline count, or pilot dimensions
• Servicing Nissan Quest, Nissan Altima, and Nissan Maxima transmission repairs

Installation Notes and Tips

Verify the converter codes 43A260, 43A261, 433, 437, and Y51 against the original unit before installation. Confirm the transmission’s spline count, pilot dimensions, mounting thread size, and bolt circle match TO86 exactly. Always inspect the transmission, cooler, and related components for contamination or damage before installing a replacement torque converter.

Quality Assurance

TC Remanufacturing supplies transmission hard parts with application-specific dimensions and identification details to support accurate replacement selection. Confirm fitment by year, model, and converter specifications before purchase.
