Automatic Transmission Control Module – Mazda (l3f2189e1d)

Automatic Transmission Control Module is an electrically controlled component in the engine or transmission management system. Because the module cross-checks it against other inputs, a fault here often surfaces as a code for a different circuit.

Replace the Control Module when a value freezes or drops out intermittently, which usually means an internal fault rather than wiring. Wiggle-testing the harness while watching live data separates the two.

This Control Module is listed under part number l3f2189e1d, filed under Transmission Control. If the original number is unreadable, send us the VIN and we will confirm the reference before dispatch.

This is genuine MAZDA stock, supplied for the Control Module with the manufacturer number intact so the reference on the box matches the catalogue.
