Today, an automatic transmission seems to be an integral part of comfortable driving, but few people know that its history goes back more than 80 years old. The first production car with an automatic transmission rolled off the assembly line in the distant 1939, but the path to this invention was long and thorny. If you've ever wondered in what year did the automatic machine appear in the car? and how it has evolved over the decades, this article will reveal all the details - from experimental prototypes to modern adaptive robots.
Today, an automatic gearbox (automatic transmission) is installed on more than 90% of new cars in the USA and Europe, and in some countries (for example, Japan) mechanical boxes have become a rarity. But this was not always the case: the first automatic transmissions were bulky, unreliable and cost exorbitant amounts of money. How did you manage to overcome these limitations? Let's take it in order.
1939: the birth of the first serial automatic transmission - Hydra-Matic from General Motors
Officially, the first production automatic transmission was Hydra-Matic, developed by an engineer Earl Thompson for the concern General Motors. Her debut took place in 1939 on the model Oldsmobile Custom 8 Cruiser, and already in 1940 the transmission became an option for Cadillac Series 61 and Pontiac Torpedo. It's interesting that initially Hydra-Matic was positioned as a luxury option - its cost was about $57 (equivalent to ~$1200 today).
Structurally Hydra-Matic was hydromechanical: It combined a torque converter (instead of a clutch) and a four-speed planetary gearbox. Shifting occurred automatically depending on speed and load, but the driver could manually lock the top gear for overtaking. By the way, this box became so successful that it was even installed on tanks M4 Sherman during World War II!
- 🔧 Technical features: 4 stages, torque converter, weight ~150 kg.
- 💰 Cost: $57 (1940) - more expensive than a manual transmission.
- 🚗 First models: Oldsmobile Custom 8, Cadillac Series 61.
- ⚙️ Innovation: The first mass-produced automatic transmission with automatic shifting.
⚠️ Attention: First versions Hydra-Matic did not have a parking mode (P) - neutral was used instead (N), and a handbrake was required to keep the car in park.
The evolution of automatic machines: from hydromechanics to electronics (1950–1990s)
After the war, automatic transmissions began to actively develop. B 1950 company Buick presented Dynaflow - first automatic transmission with fully automatic control (without manual gear blocking). And in 1956 Chrysler released PowerFlite - a compact and reliable box that has become standard for many American cars.
An important breakthrough occurred in 1980swhen they appeared electronic control systems. For example, in 1982 BMW presented 4HP22 — the first automatic transmission with a microprocessor unit that analyzed driving style and adjusted shifts. This was the beginning of an era adaptive machineswho studied to be a driver.
| Year | Automatic transmission model | Manufacturer | Innovation |
|---|---|---|---|
| 1950 | Dynaflow | Buick | The first fully automatic transmission without manual control |
| 1956 | PowerFlite | Chrysler | Compact and robust design for the mass market |
| 1982 | 4HP22 | BMW/ZF | The first automatic transmission with an electronic control unit |
| 1990 | 4L60-E | General Motors | Electronic control with adaptive algorithms |
K 1990s automatic transmissions have become standard equipment for most mid- and premium-class cars. Appeared 6-speed automatic transmission (for example, Mercedes 722.6 in 1996), alater — and stepless variators (CVT) which was offered Nissan in the model March (1992).
The first slot machines in Europe and Japan: who was ahead of the competition?
While the United States led the way in the development of automatics, European and Japanese manufacturers have long favored manual transmissions. However, to 1960s the situation began to change:
- 🇩🇪 1961: Mercedes-Benz presented 4G-Tronic — the first German automatic transmission with a torque converter. It was installed on flagship sedans W111 and W112.
- 🇯🇵 1968: Toyota released Corona Mark II with automatic transmission Toyoglide — the first Japanese automatic transmission of its own design.
- 🇬🇧 1970: Jaguar started installing BorgWarner Model 8 on XJ6, making the automatic available for British luxury cars.
Interestingly, in Japan, machine guns spread more slowly due to fuel economy culture - manual transmissions were considered more efficient. However, to 1980 the situation has changed: Honda and Nissan began to actively introduce automatic transmissions into mass models, such as Honda Accord (1982) and Nissan Bluebird (1983).
Why did Europeans take so long to accept machine guns?
Until the 1980s in Europe, automatics were associated with a “lazy” driving style and were considered less reliable than manuals. In addition, narrow city streets and high fuel costs made manual transmission a more practical choice. The situation changed only with the advent of economical 4- and 5-speed automatic transmissions.
Robotic boxes and CVTs: revolution of the 2000s
At the turn of the century, automatic transmissions experienced a real revolution. B 2003 Volkswagen presented DSG (Direct-Shift Gearbox) - first robotic gearbox with dual clutch. It combined the shift speed of a manual with the comfort of an automatic, becoming a hit among sports cars.
Developed in parallel variators (CVT):
- Nissan in 1992 was the first to produce a serial variator on March.
- Toyota in 1997 presented Prius with a CVT optimized for hybrid vehicles.
- K 2010 CVTs have become standard on many Japanese and American models (e.g. Subaru Forester, Honda Fit).
⚠️ Attention: Early CVTs (before 2005) were often criticized for their “rubbery” effect during acceleration and low reliability. Modern CVTs (e.g. Nissan Xtronic or Toyota Direct Shift-CVT) are free from these shortcomings thanks to imitation steps and reinforced belts.
Today the market offers several types of machines:
- Classic hydromechanical automatic transmissions (6–10 steps, e.g. ZF 8HP).
- Robots with one/double clutches (for example, DSG from VW or Powershift from Ford).
- CVTs (CVT) with imitation steps.
- Hybrid powertrains (for example, e-CVT in Toyota Prius).

Current trends: automatic machines for electric vehicles and autonomous driving
With the advent of electric vehicles, classic automatic transmissions began to become a thing of the past. Most EV (for example, Tesla Model 3 or Nissan Leaf) cost single-stage gearbox, since the electric motor does not require a multi-range transmission. However there are exceptions:
- Porsche Taycan (2019) uses two-speed gearbox to improve dynamics.
- Rimac Nevera (2021) equipped single-speed transmission with a unique gear ratio.
In the future, automatic transmissions may evolve towards fully adaptive systems, integrated with autonomous driving. For example, BMW and Mercedes they are already testing transmissions that independently select a mode (sport/economy) based on data from cameras and radars.
| Technology | Model example | Year of appearance | Benefits |
|---|---|---|---|
| Single-stage gearbox (EV) | Tesla Model S | 2012 | Simplicity, reliability, instant torque |
| Two-speed transmission (EV) | Porsche Taycan | 2019 | Better dynamics at high speeds |
| Adaptive automatic transmission with AI | Mercedes EQS (prototype) | 2023 | Self-training based on driving style and road conditions |
Myths and truth about automatic transmissions
There are many misconceptions associated with slot machines. Let's look at the most common ones:
- ❌ Myth: "Automatic machines are always less reliable than manual ones."
✅ Truth: Modern automatic transmissions (for example, ZF 8HP or Aisin AWR6B45) with proper maintenance serve 250,000+ km. CVTs and robots of early generations (before 2010) were indeed problematic, but new models are not inferior to mechanics.
- ❌ Myth: "The automatic increases fuel consumption."
✅ Truth: Modern 8–10-speed automatic transmissions (for example, in Hyundai Santa Fe or Kia Sorento) may be more economical than mechanics due to optimal gear ratios.
- ❌ Myth: “You can’t tow a trailer with an automatic.”
✅ Truth: Most automatic transmissions (except for CVTs without locking) allow towing, but with weight restrictions (usually up to 2–2.5 tons). It is important to check the instructions for your specific model!
If you are buying a used car with an automatic transmission, be sure to check the transmission oil change history. Many problems (jerking, delays) are associated with contaminated or outdated oil, and not with mechanical failures.
FAQ: Frequently asked questions about the history of slot machines
🔍 In what year did the first production car with an automatic transmission appear?
The first production car with automatic transmission - Oldsmobile Custom 8 Cruiser 1939, equipped with box Hydra-Matic from General Motors.
🔍 Which automatic transmission was the most reliable in the 1990–2000s?
The leaders in reliability were considered:
- ZF 5HP19 (installed on BMW 5-series E39),
- Aisin A340E (Toyota Land Cruiser 80/100),
- Mercedes 722.6 (5-speed, used until 2010s).
These boxes often passed 300,000+ km without major repairs.
🔍 Why weren’t there cars with automatic weapons in the USSR?
In the Soviet Union, automatic transmissions were not produced due to:
- high cost (priority was given to cheap and simple machines),
- lack of technology for mass production of torque converters,
- driving culture — the mechanics were considered more “masculine” and reliable.
The only exception was ZIL-111 (1959) - government limousine with automatic transmission Hydra-Matic, but it was an imported transmission.
🔍 Which automatic transmission is the most modern for 2026?
Today the most advanced are:
- ZF 8HP Gen.4 (8 steps, used in BMW M5, Land Rover Defender),
- Mercedes 9G-Tronic (9 steps, adaptive algorithms),
- Toyota Direct Shift-10DAT (10 steps for pickups Tundra),
- Porsche PDK (7-speed dual-clutch automatic transmission for 911 and Taycan).
Also actively developing continuously variable transmissions with virtual gears (for example, Nissan Xtronic).
🔍 Is it possible to convert a manual into an automatic in an old car?
Technically possible, but it requires:
- selection of a compatible automatic transmission (for example, for VAZ-2107 fits the box from Nissan Almera N16),
- improvements to fasteners, cardan, electronics,
- flashing the ECU (if the car is fuel-injected).
Cost such tuning often exceeds the market price of the car. For classic cars (eg Mercedes W123) there are ready-made kits, but their installation costs 1500–3000$.The first serial automatic transmission appeared in 1939, but the mass distribution of automatic transmissions began only in the 1980–1990s thanks to electronic control systems and lower production costs.
