325I E90 (silver) N43B20 320I F30 N43B20 (A)

Tovesageneral Motors lists this 325I E90 (silver) N43B20 320I F30 N43B20 (A) as a used, inspected automatic transmission. It comes out of a working vehicle rather than a parts-bin unknown: we drain and check the fluid, inspect the case and gear train for visible wear, and test shift engagement where the unit's condition allows before it ever reaches the shelf.

Key Specifications: Every internal component and the housing itself are the original factory design for this BMW application, no reproduction parts. Transmission type: Automatic (torque converter). We list the gear count as application-dependent for the 325I E90 (silver) N43B20 320I F30 N43B20 (A): several ratio sets were fitted across different markets and trim levels, so confirm against your old unit or VIN before ordering. Compatible engine(s): N43B20 engine variants. Since the 325I E90 (silver) N43B20 320I F30 N43B20 (A) platform spans multiple drivetrain configurations, confirm your chassis's drive layout against the listing before ordering to be certain of fitment.

Performance Characteristics: As an automatic unit, smooth shift quality depends heavily on fluid condition and the health of the valve body and solenoids, so a fluid and filter service at installation is worth doing even on a freshly tested used unit.

Common Applications: Expect this unit to fit BMW vehicles that were factory-paired with the N43B20 driveline described above. Because the same casting is often reused across multiple model years with small internal or electronic revisions, we recommend confirming the exact spline count and control variant against your vehicle, or simply sending your VIN so our team can verify fitment ahead of time.
