The days when potential used car buyers were afraid of automatic transmissions are long gone. A modern motorist trusts a classic torque converter more than robotic transmissions and CVTs. Some automatic transmission models are less problematic than mechanics. The automatic transmission is reliable, and this has been proven for years. Among them there are real centenarians. Let's see which is the most reliable automatic transmission. This information will be very useful for those who are thinking about buying a used car on the machine.
Small review
It should be remembered that an automatic transmission is a complex unit that requires timely maintenance. Also, the automatic transmission is very sensitive to violation of the rules of operation. The main enemies of any machine are overheating and irregular oil changes.
Modern automatic transmissions work with powerful engines in harsh conditions. If we compare modern boxes with old 4-speed transmissions, then the secondlive in a more relaxed rhythm, and this is the secret of their great runs. In addition, these models are based on old technologies, and their design is well known to specialists.
Do not be surprised that the newest automatic transmissions are not in the review. This is due to the fact that there is still no repair statistics for the latest units of the 2017-2019 model years. The most reliable modern automatic transmissions have not yet been studied. Therefore, in the ranking only the most common representatives in the automotive market.
ZF 5HP 24/30
It was this automatic transmission that proved to be the most reliable. Runs before overhaul during normal operation amounted to about 500 thousand kilometers.
This is the famous five-speed automatic, which is provided by the manufacturer for powerful engines located longitudinally. The automatic transmission was made for rear-wheel drive cars. The first version was created back in 1992. The transmission was operated mainly with powerful 8- and 12-cylinder BMW power units, as well as other similar engines of legendary cars. These are Rolls Royce, Bentley, Aston Martin.
This is the very first automatic transmission capable of handling a maximum torque of 560 Nm. Then, after upgrading and improving the 5HP24 model, this box was installed on Jaguars and Land Rovers. In 1997, the manufacturer did a good job, and the world saw an even more advanced modification of the legend. This is 5HP24A. It was intended for rear-wheel drive vehicles, and could also be installed andto all-wheel drive.
This proves that powerful motors in no way affect the durability and resource of automatic transmissions. The knot is practically “indestructible”, the margin of safety is huge, there are simply no visible flaws in the design. This automatic transmission reaches record numbers in terms of resource. And this is the most reliable automatic transmission at the moment.
GM 5L40-E
Another old but reliable machine. This five-speed automatic transmission was created in 1999 by GM, USA.
It was installed on rear-wheel drive cars with a longitudinal installation of the power unit. Initially, the automatic transmission was installed on the BMW 323i, 328i models in the E46 body. In 2000, a new version of the transmission was developed, already for all-wheel drive. And from that moment on, this most reliable automatic transmission was used all over the world - from the BMW X5 to the Honda. Automatic transmission could easily digest 420 Nm of torque. This is a strong and very reliable transmission. She easily nurses about 450 thousand kilometers before a major overhaul.
545 RFE
This is a machine from 2003. Five-speed automatic transmission, replacing the 4-speed 45 RFE. The first car to use such automatic transmissions was the Jeep Grand Cherokee WJ. Later, the transmission was installed on all other models of this brand. The box was also used in pickup trucks manufactured by Dodge.
If you ask an American car service which cars have the most reliable automatic transmissions, then experts will name the models with this gearbox. Destroytransmission is not possible. It is designed for high loads. It is for these qualities that this machine is widely used in London taxi cars. The automatic transmission is very pleasant to operate, and the shifts are soft. The immediate need for repairs, subject to proper operation, will be needed no earlier than after 400 thousand kilometers.
A340
This is no longer the US, but no less reliable Japan. The presented box can be considered one of the most reliable automatic transmissions. One of its main advantages is its enormous durability. After 400 thousand kilometers, you only need to replace consumables, and the mechanism will last the same amount without problems.
A driver may begin to think about the first major repair of the unit no earlier than after 700 thousand kilometers. The transmission, which has four steps, is designed for front-wheel drive cars, rear-wheel drive cars, as well as all-wheel drive versions. The box is old, and in 1986 the Japanese released the A350 version - it is already a five-speed one.
It was equipped with Toyota 4Runner, Supra, Lexus GS, LS. These are the most reliable cars with automatic transmission.
A750
Japanese five-speed automatic transmission is a leader in reliability even under heavy loads. The machine was designed specifically for powerful engines and massive cars. The plant has been producing these automatic transmissions since 2003, and they exist until today. The mechanism works slowly, but its dignity is not in this - the box can really be trusted. Any modern machine of any brand can only envy the brainchild of Japaneseengineers. After all, the mileage before the overhaul is 400 thousand kilometers or more.
"Mercedes" 722.4
Everyone knows that the Germans create such cars and spare parts for them, which are of a very high level of quality. One of the legendary products of this brand is a four-speed automatic 722.4.
There are many legends about its resource, and it is considered the most reliable automatic transmission on Mercedes cars. It has been installed since the 80s of the last century. And even then it managed to get the highest ratings for reliability and resource. Automatic transmission works with different engines - from small four-cylinder to large V6 and V8. It is very difficult to destroy an automatic transmission - a special "talent" is needed here. Before the overhaul, the unit easily travels 600 thousand kilometers. However, scheduled maintenance has not been canceled. In order for the box to have a truly good resource reserve, you need to regularly replace the ATP fluid.
Jeep A904
The first version appeared in 1960. Therefore, its design is archaic, and there are only three gears. This is the main advantage - having a simple device, it does not require special care and repair.
FN4A-EL, 4F27E
This machine was developed by the largest automotive giants Mazda and Ford. The first sample rolled off the assembly line in 2000. Engineers have made a very reliable transmission that does not cause any problems for the owners. The box is economical, pleasant to use. The design, in addition to all other advantages, has a wide range of revolutions. The only drawback is that there are only four steps.
With all the shortcomings of the Mazda 3 and Mazda 6, they have just such a box. The mechanism runs under the condition of competent operation of 500 thousand or more. These are the most reliable modern automatic transmissions.
Aisin U340E
This is a classic four-speed automatic found on many Toyota models. Automatic transmission stands out for its simplicity and reliability. Only an aggressive driving style and an untimely oil change can lead to serious problems with it. But even a "dead" box is subject to repair. Perhaps this is not the most reliable automatic transmission, you will not see it on modern cars, but for those who appreciate economy and comfort along with reliability, this is a good option.
Jatco JF414E
It's a four-speed transmission again. Her age is already quite respectable - production began in 1989.
Automatic transmission has earned the love of the consumer for successful settings that give good dynamics. Due to the simplicity and sparing modes, the resource of the mechanism is very high. You can see the box on domestic cars from VAZ and their Chinese relatives.
Conclusion
We examined which automatic transmissions are the most reliable. As you can see, these are mostly Japanese and German models. The list is very large, and therefore it is safe to say that in the secondary market you can still find quitegood cars with automatic transmission, which will not become a burden for the future owner.
