Detailed Description

TC Remanufacturing B31HS is an OE-style automatic transmission torque converter for 1989-1998 Suzuki Sidekick, 1989-1997 Geo Tracker, and 1998 Chevrolet Tracker applications. The lock-up design supports direct coupling at cruise, while the high-stall calibration and 10.250-inch diameter match the listed transmission requirements. With a slotted hub, 3-pad mounting, 27-spline count, and the specified pilot dimensions, this B31HS torque converter is built around the fitment and interface details needed for the correct transmission assembly.

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

What This Part Is Used For

• Replacing a worn or failing torque converter in a Tracker or Sidekick automatic transmission
• Addressing shudder, slip, or inconsistent lock-up operation
• Restoring proper engine-to-transmission coupling during acceleration and cruise
• Correcting drivability issues tied to converter wear or internal failure
• Matching the specified converter codes for the listed vehicle applications

Installation Notes and Tips

Verify the transmission code, converter code, spline count, pilot diameter, pilot length, bolt circle, and mounting style before installation. Confirm that the 10.250-inch diameter and lock-up configuration match the original unit for your Chevrolet Tracker, Suzuki Sidekick, or Geo Tracker application. Inspect the transmission fluid, cooler, and related components during replacement to help prevent repeat converter damage.

Quality Assurance

TC Remanufacturing supplies transmission hard parts and remanufactured drivetrain components for service replacement applications. B31HS is specified to match the listed fitment and dimensional requirements for the covered vehicles.
