Can Aisin 6AT Run for 1 Million Kilometers?

Aisin 6AT cannot run for 1 million kilometers. Below is an extended introduction to it: Introduction to Aisin 6AT Transmission: Generally, the Sagitar Aisin 6AT transmission has a lifespan of about 200,000 kilometers, but this must be under the premise of standardized driving. The Aisin 6AT uses a transmission with two sets of planetary gears, which can reduce fuel consumption during upshifts and thus expand the lock-up range design, while also adopting advanced structural technology with a fuel-saving valve. Aisin 6AT Transmission Maintenance: It is necessary to regularly check the transmission fluid and replace it in time, with a replacement cycle generally between 40,000 to 60,000 kilometers. Never start the engine in any gear other than N or P, and do not engage R gear while the vehicle is in motion.
Just helped an old classmate inspect a Camry with 580,000 km on the odometer the other day, equipped with the Aisin 6AT. This transmission is indeed durable—as long as you change the oil on time, hitting 1 million km is not a pipe dream. The most extreme case I've seen was a Shenzhen taxi showing 1.03 million km without a major transmission overhaul. But a heads-up: never skimp on regular maintenance. Changing the original transmission fluid every 60,000 km is a must. If you frequently carry heavy loads, climb hills, or drive aggressively, you'll need to shorten the fluid change interval even further. Also, pay close attention to the cooling system, as high temperatures are the number one killer of transmissions.
Our auto repair shop has disassembled three Aisin 6AT transmissions with over a million kilometers, and found minimal wear on core components. Those precision planetary gears and torque converters were designed with ample redundancy. But honestly, hitting a million kilometers with an automatic transmission depends on luck - it's heavily influenced by engine compatibility and driving habits. I recommend inspecting the valve body during every maintenance after 200,000 km. If metal shavings on the oil pan magnet accumulate more than sesame seeds, it's time to be cautious. I once serviced a Lexus RX whose owner religiously changed fluid every 30,000 km for ten years - at 920,000 km, its gear shifts remained crisp and precise.
