Currently, the highest-quality car transmissions are the world's top ten transmissions, which include ZF transmissions, Aisin transmissions, JATCO transmissions, Powertech transmissions, DSI transmissions, Getrag transmissions, Allison transmissions (USA), Shaanxi Fast transmissions, DYMOS transmissions, and GM transmissions. Detailed information about the world's top ten transmissions is as follows: 1. ZF Transmission: ZF is one of the world's top three transmission manufacturers and a partner and parts supplier to the global automotive industry. Its transmission technology is highly advanced, offering not only very sensitive shifting but also exceptionally stable and easy control. 2. Aisin Transmission: Japan's Aisin is also one of the world's top three transmission manufacturers. Aisin's automatic transmission product lineup is very extensive, covering 4-speed, 5-speed, 6-speed, and 8-speed transmissions. 3. JATCO Transmission: JATCO is the world's third-largest automatic transmission designer and manufacturer. Founded in 1943 as JATCO Corporation in Japan, it is also one of the world's top three automatic transmission suppliers. 4. Powertech Transmission: Hyundai Powertech is part of South Korea's Hyundai Motor Group and is the largest domestic producer of 6-speed automatic transmissions. 5. DSI Transmission: DSI was established in 1928 in Australia, with major clients including Geely Auto, SsangYong Motor, BAIC Yinxiang, Soueast Motor, Lifan Auto, SWM Motor, and BYD Auto. 6. Getrag Transmission: Germany's Getrag is one of the world's largest independent transmission manufacturers and a globally renowned supplier of passenger and commercial vehicle transmission systems. 7. Allison Transmission (USA): Allison is the world's most famous manufacturer of heavy-duty vehicle transmissions, producing automatic transmissions for heavy-duty vehicles. 8. Shaanxi Fast Transmission: Shaanxi Fast Group is China's largest manufacturer of heavy-duty vehicle transmissions, ranking first in the national gear industry for six consecutive years and leading the world in production and sales of heavy-duty transmissions. 9. DYMOS Transmission: DYMOS is a joint investment by Hyundai Dymos, Hyundai Motor Company, and Kia Motors Corporation, producing 730,000 transmissions annually. 10. GM Transmission: GM transmissions are manufactured by General Motors, with GM's MT and AT transmissions also being quite renowned in the industry.

In my over 20 years of car repair career, I've seen countless transmission failures and repairs. The best in terms of quality and reliability are Aisin's automatic transmissions, especially those fitted in Toyota Prius or Camry models - their failure rate is astonishingly low. Some have run over 100,000 kilometers with only oil changes and minimal wear. ZF's 8-speed automatic transmissions used in BMW X5 or Audi A6 are also top-notch, offering smooth shifting and durability with few issues, but replacement parts are prohibitively expensive - a new one can cost tens of thousands. Honda's CVT is lightweight and fuel-efficient; Civic models for family use often run seven or eight years without major issues, with simple and cost-effective maintenance. Manual transmissions like early Nissan's were quite robust, but young people find them troublesome and they're nearly extinct now. With electric vehicles coming, direct drive eliminates transmissions altogether, making things even more worry-free. I usually recommend owners check transmission fluids every 60,000 kilometers - don't skimp on maintenance only to face major failures later.
