In the transmission assembly between engine and driven axles.

How it works

Steptronic is a BMW shifting designation; the underlying automatic hardware depends on the application.

Think of it as

An automatic gear selector that also accepts your requests.

Symptoms when it fails

Harsh shifts or delayed engagement can involve software, fluid condition, mounts or internal faults.

Lifespan

Use the exact gearbox and axle service guidance. Loads, seals, lubricant condition and driving use influence wear.

Repair cost

An accessible mount or seal differs from internal transmission work. Gearbox identification and diagnosis are essential to a useful quote.

The BMW angle

The word Steptronic does not by itself identify a specific gearbox manufacturer or mechanism.

Used in

BMW rear-drive, front-drive and xDrive applications as equipped; layouts differ by platform.
