TC Remanufacturing TO87 Automatic Transmission Torque Converter

TC Remanufacturing TO87 Torque Converter

The TC Remanufacturing TO87 is an automatic transmission torque converter built for specific Toyota and Lexus applications with a lock-up design, very low stall, and OE-style mounting dimensions. It is a direct-fit option for drivers servicing a Toyota Camry, Toyota Avalon, Lexus ES350, Lexus RX350, Toyota Sienna, or Toyota Venza transmission.

Key Features

• Part number TO87 from TC Remanufacturing
• Automatic transmission torque converter with lock-up operation
• 11.250-inch converter diameter
• Very low stall for controlled engagement characteristics
• 6-pad mounting type with 9mm x 1.25 mounting thread size
• Slotted hub type, 22 spline count, and 1.257 pilot diameter
• 9.600 bolt circle and no ring gear
• Converter codes: P, 423KA

Detailed Description

TC Remanufacturing TO87 is an automatic transmission torque converter engineered around the listed fitment and physical specifications. It uses a lock-up converter type, an 11.250-inch diameter, and a very low stall setup to match the transmission calibration used in select Toyota and Lexus vehicles. The slotted hub, 22 spline count, 6-pad mounting pattern, and 9mm x 1.25 thread size help define the correct mechanical interface for applications such as 2007-2017 Lexus ES350, 2007-2016 Toyota Camry, 2011-2016 Toyota Sienna, 2010-2015 Lexus RX350, 2009-2015 Toyota Venza, and 2008-2014 Toyota Avalon. The TO87 part number is also identified by converter codes P and 423KA for matching purposes.

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

What It Helps Address

• Torque converter shudder during lock-up operation
• Delayed or inconsistent engagement from a worn converter
• Transmission slip related to internal converter wear
• Excessive heat generation caused by inefficient converter operation
• Drivability concerns tied to incorrect stall characteristics

Installation Notes and Tips

Verify the converter codes P and 423KA before installation on applicable Toyota Avalon and Lexus RX350 applications. Confirm the 11.250-inch diameter, 22 spline count, 1.257 pilot diameter, 6-pad mounting pattern, and 9mm x 1.25 thread size against the removed unit and transmission specifications. Flush the transmission cooler and inspect related hard parts before installing the replacement torque converter to reduce the risk of contamination-related failure.

Quality Assurance

TC Remanufacturing supplies transmission hard parts and torque converters for application-specific replacement work. This TO87 unit is built to match the listed OE-style fitment and dimensional requirements for the covered Toyota and Lexus vehicles.
