If the oil is changed regularly every 50,000–60,000 km, its lifespan can reach 400,000–500,000 km.

The German ZF transmissions are found in premium vehicles such as BMW, Audi, Jaguar, Range Rover, and even Rolls-Royce. The 6HP model has become a classic, while the 8HP is one of the most modern transmissions. They handle aggressive driving styles excellently but are very sensitive to oil quality. With timely maintenance, their lifespan exceeds 350,000–400,000 km.

Honda 5AT/6AT

After initial problems with early versions, the later generations of the 5- and 6-speed gearboxes from Honda became examples of reliability. They were installed in Accord, CR-V, Odyssey, and Pilot. The key to their longevity is the simplicity of the design and the use of high-quality materials. These automatic transmissions are known for their ease of maintenance and durability.

The 5-speed automatic became a legend in the early 2000s. It was installed in powerful E-, S-, and ML-classes, as well as in some Chrysler and Jeep models. This transmission can endure huge mileages, operates smoothly and reliably even with powerful V8 engines. There are cases where this automatic transmission has exceeded 700,000–800,000 km without serious repairs.

Repairing an automatic transmission can be very costly for the owner, so it is essential to choose cars with reliable gearboxes and strictly follow maintenance recommendations.
