Purpose and function in the drivetrain

The flywheel in an automatic transmission is responsible for the stable transfer of torque between the engine and the transmission, as well as for damping torsional vibrations. The presented solution uses a design consistent with BMW factory standards, which allows for maintaining the engine's smooth operation and the correct functioning of the gear shifting system.

Thanks to its fitment for specific body series, the flywheel works with original accessory components, such as the torque converter or the starter system. This allows for maintaining predictable vehicle behavior both during start-up and during dynamic acceleration.

Compatibility with automatic transmission

The presented flywheel is intended for vehicles equipped with an automatic transmission, which is crucial when selecting parts. The design is prepared to work with a torque converter, ensuring a proper connection to the crankshaft and maintaining the alignment of the entire assembly.

Selecting the correct flywheel for an automatic transmission affects:

• proper engagement with the starter,
• stable transfer of dynamic loads,
• reduction of vibration and noise in the cabin,
• longevity of the transmission and cooperating components.

Characteristics of the used OEM part

The offered element comes from the line of original BMW components, which means maintaining factory material and dimensional parameters. The used part allows for an economical repair while maintaining compliance with the manufacturer's service documentation.

Choosing an original flywheel from the secondary market is beneficial wherever it is important to:

• maintain the serial operating characteristics of the engine and transmission,
• ensure compatibility with a specific generation of the powertrain,
• reduce costs compared to a new OEM component.

Application in BMW models

BMW E90 E91 LCI F10 F30 F31 F32 Automatic Gearbox Flywheel is dedicated to selected versions of popular BMW series, making it an attractive solution for repairs and drivetrain upgrades. Using parts from the same design group allows for maintaining the consistency of technical solutions within a given vehicle platform.

Before installation, it is recommended to verify compatibility with the specific engine version and automatic transmission type to ensure proper fitment with other system components.

Support with selection and tuning based on used parts

The flywheel is an important element in drivetrain modifications, especially when changes to the engine or transmission operating characteristics are planned. Many projects utilize components from the secondary market, combining them with other service or tuning solutions.
