Automatic Transmission Torque Converter
This TC Remanufacturing torque converter is built for BMW automatic transmission applications that require a lock-up design with a 1900-2100 stall range. It is identified by part number B25SGHS and uses converter codes 24200343, 24210707, SG9S, and SGHS.
Compatible With BMW 318i, 318is, 318ti, and 528i automatic transmission applications, this unit is configured with a 10.100-inch converter diameter, 9.250-inch bolt circle, 27-spline count, and a slotted hub. The three-pad mounting design uses 10mm x 1.5 threads, with a 1.257-inch pilot diameter and 1.140-inch pilot length. The ring gear is not included in the converter design.
Key Features
- Lock-up torque converter design for controlled drivetrain coupling.
- 1900-2100 stall range for matched transmission response.
- 10.100-inch diameter with a 9.250-inch bolt circle.
- Slotted hub and 27-spline configuration.
- Three-pad mounting pattern with 10mm x 1.5 threads.
- Part number B25SGHS for identification and ordering.
What It Is Used For
- Restoring proper torque transfer in an automatic transmission.
- Addressing shudder or inconsistent lock-up operation.
- Replacing a worn converter with incorrect stall behavior.
- Correcting fitment issues tied to converter code matching.
Installation Notes and Tips
Verify converter codes 24200343, 24210707, SG9S, and SGHS before installation. Confirm the transmission’s bolt circle, spline count, pilot dimensions, and mounting pad configuration match the replacement unit. For BMW 318i, 318is, 318ti, and 528i applications, compare the existing converter and transmission identification carefully to ensure proper fitment. Part number B25SGHS should be matched to the vehicle’s transmission requirements before assembly.
Quality Assurance
TC Remanufacturing identifies this torque converter by specific converter codes and dimensional specifications for application matching. Part number B25SGHS is listed for BMW automatic transmission use where the lock-up design and stall range align with the original setup.
