The offered gearbox is part of the original BMW powertrain, designed for the specifics of the 60Ah Rex hybrid unit, which translates into seamless integration with the vehicle's electronics and optimized performance characteristics in terms of energy efficiency.

For users looking for a professional, technically matched solution for their i3, this automatic transmission provides a solid foundation for repairing or replacing a damaged component while maintaining BMW's factory design concept.

Purpose and technical characteristics

The presented gearbox belongs to the BMW automatic transmissions group and was developed for the specific hybrid system of the i3 I01 model with a 60Ah battery and Rex module. The design is integrated with the electric drive, allowing for harmonious cooperation with torque management systems and energy recuperation.

The Automatic type means that gear shifting is controlled fully electronically, without driver intervention, which is crucial in electric and hybrid vehicles where the priority is smooth acceleration, the absence of jerking, and stable operation across a wide range of loads.

Benefits of using an original BMW gearbox

Using a gearbox dedicated to the BMW i3 I01 Hybrid 60Ah Rex ensures:

• consistency with the factory powertrain control software,
• proper matching to the characteristics of the electric motor and the Rex unit,
• preservation of the dynamics and refinement intended by the manufacturer,
• minimization of the risk of mechanical and electronic compatibility issues.

As a result, the vehicle maintains predictable road behavior, and the powertrain operates within the parameters for which it was designed. This is particularly important in the case of hybrids, where the gearbox is closely linked to energy management systems.

Application in service practice

The automatic transmission in the BMW i3 is responsible for transferring torque from the powertrain to the wheels while working in conjunction with safety and stability control systems. Replacing it with a component from the same design line allows for maintaining:

• proper cooperation with the vehicle's control modules,
• compliance with factory diagnostic procedures,
• the possibility of further service maintenance based on standard BMW tools.

This solution is recommended for workshops specializing in the brand and for users who expect the most trouble-free installation and configuration within the existing vehicle architecture.

Condition and origin of the component

The offered gearbox is a used component, sourced from an original BMW powertrain. Such components are a popular choice as an alternative to new parts, especially in the case of technologically advanced hybrid drives, where the cost of brand-new parts is significant.

For informed users and service centers, this represents a reasonable compromise between repair costs and maintaining a design consistent with the manufacturer's specifications, while simultaneously upholding the high functionality of the powertrain.

Selection by OEM and VIN – expert support

When selecting an automatic transmission for the BMW i3 I01, it is crucial to verify compatibility using the OEM number and the vehicle's VIN. This helps avoid compatibility issues and ensures proper cooperation with the control electronics. If you want to deepen your knowledge regarding the procedures for selecting used powertrain components, it is worth checking out the expert guide Why it is worth buying used gearboxes and engines – facts instead of myths, which discusses, among other things, OEM numbers, real savings, and common market myths.

Additionally, when making a decision to purchase a used gearbox, a practical resource describing the cost-effectiveness of such a solution and the technical aspects of installation may be helpful – you can find it in the article Used gearbox – when is it worth it and what you need to remember, where different types of transmissions are compared and key selection criteria are discussed.
