Transmission Control Module Bracket – Mazda (bp5b18945a)

Transmission Control Module Bracket is part of the circuit that reports engine or transmission behaviour back to the control module. It is read continuously, and a value that drifts out of range sets a fault code long before the driver notices anything.

Replace the Control Module Bracket when the code returns after clearing, when the live data reading is out of range at operating temperature, or when the housing shows heat damage. Check the ground and the connector pins first.

The Control Module Bracket in this listing carries part number bp5b18945a and sits in the Transmission Control category. The number stamped on the original part is the only reliable cross-reference.

This is MAZDA dealer-sourced stock rather than an equivalent, so the number on the Control Module Bracket traces straight back to the manufacturer.
