Product Details

This TC Remanufacturing torque converter is specified for automatic transmission service where the original unit uses a non-lock-up design, a 19-spline input, and the listed mounting and pilot dimensions. The MC12 part number helps identify the correct replacement when matching converter diameter, bolt circle, hub style, and stall characteristics for the transmission build.

For buyers searching for an automatic transmission torque converter for Honda Civic or similar vehicle-specific applications, the key is matching the converter code, spline count, and mounting pattern to the transmission rather than relying on appearance alone. TC Remanufacturing MC12 is built around those dimensional requirements for accurate replacement selection.

Common Problems This Part Can Address

• Transmission shudder or poor engagement caused by a worn torque converter
• Incorrect stall behavior after converter wear or internal failure
• Vibration or fitment issues from a mismatched bolt circle or pilot size
• Driveability concerns tied to a damaged hub or spline interface
• Converter code mismatch during automatic transmission repair

Installation Notes and Tips

Verify the transmission code, converter code, spline count, bolt circle, pilot diameter, pilot length, and mounting thread size before installation. Confirm that the 10.000-inch diameter and non-lock-up design match the original unit, and inspect the flexplate, pump, and transmission input components for wear before final assembly. Proper fluid fill and converter seating are critical before starting the engine.

Quality Assurance

TC Remanufacturing supplies remanufactured drivetrain components for transmission service, and this MC12 torque converter is identified by its converter code and dimensional specifications for accurate parts matching.
