What It Helps Address

• Transmission fluid contamination from normal wear and debris
• Fluid drain-back after shutdown
• Restricted flow caused by a loaded filter element
• Service replacement for OE-numbered filter applications
• Routine maintenance on older spin-on transmission filter setups

Installation Notes

Confirm thread size, gasket seating surface, and OE cross-reference before installation. Baldwin B227 uses an M20 x 1.5 thread and includes an integral gasket, so the sealing surface should be clean and free of old gasket material before tightening. Verify the vehicle’s transmission filter specification against the application listing, especially on Mitsubishi, Honda, and Hyundai/Kia models with OE-numbered service parts.

For best results, replace the filter during scheduled transmission service and inspect the pan, fluid condition, and mating surfaces at the same time. The B227 part number should be matched to the exact transmission application rather than the engine model alone.

Quality Assurance

Baldwin is known for filtration products used in automotive and engine service applications. This filter is built with the listed anti-drainback valve, by-pass valve setting, and gasket specification to support consistent service replacement performance.
