Detailed Description

TC Remanufacturing B25SJHS is an automatic transmission torque converter engineered for BMW drivetrains that use the listed converter codes and dimensions. This lock-up unit is specified with a 10.100-inch diameter, 27-spline hub, and mid-stall behavior, making it a direct-match service part for the covered BMW 3 Series, 5 Series, and Z3 applications. The B25SJHS part number is also useful when verifying replacement against the original converter code on the vehicle.

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

What It Helps Resolve

• Transmission shudder during lock-up operation
• Delayed or inconsistent engagement from a worn converter
• Excessive slip under load
• Vibration or drivability issues tied to converter wear
• Incorrect replacement when matching BMW converter codes

Installation Notes and Tips

Verify the converter code, spline count, bolt circle, pilot dimensions, and mounting style before installation. Confirm transmission compatibility against the vehicle’s original unit, especially on BMW 325i, 328i, and 528i applications where multiple converter codes may exist. Inspect the transmission fluid, cooler lines, and flexplate condition during service to help prevent repeat failure. The B25SJHS should be matched to the exact application listed in the fitment data.

Quality Assurance

TC Remanufacturing supplies remanufactured drivetrain components with application-specific identification details to support accurate replacement selection. Use the listed converter codes and fitment information to confirm the correct BMW torque converter before installation.
