Difference Between 4L60E and 4L80E (With Table)

4L60E and 4L80E are the series of automatic transmissions made available by general motors. Introduced in 1982 and 1963 respectively, these transmissions are regarded as efficient and revolutionary for their times.

4L60E and 4L80E consist of longitudinal engine configurations. This means that they consist of four forward gears and one reverse gear for 4L60E.

4L60E vs 4L80E

The main difference between 4L60E and 4L80E is that they belong to different period of manufacturing. 4L60E is a transmission that was introduced in the early eighties whereas 4L80E was relevant around the sixties. They both were in use for Chevrolet cars.4L60E was first produced in Ohio by Toledo Transmission.

4L60E was first manufactured by Willow Run Transmission in the state of Michigan. They were initially made for Bentley and Rolls Royce vehicles and later on used by many popular car companies.Later on, Mexico and Michigan started producing this transmission.Plus, 4L60E comes with multiple shafts and unique torque converters.

4L80E was modified with the rigorous level of testing and was kept in production till 2013. It can handle engines with a large torque value.. It is electronically commanded and works with the assistance of “turbo-Hydramatic”. It has a strong internal space supported by four pinion plates.

What is 4L60E?

4L60E is a type of transmission that was in production nearly a decade ago. It supports almost all varieties of heavy engines and popular cars. It also sustains a higher torque value than its predecessors like 700R4 with less turbo power.

It is a lighter form of transmission and has a reverse gear option. 4L60E was designed by keeping SUVs, vans, and trucks in mind. It has a unique distinct gear ratio which includes four different gears. Over time, it received many improvements focused on the solenoid pattern.

Applications by some popular car companies

  1. Chevrolet EXT Escalade
  2. GTO Pontiac around 2005-2006

The internal structure of 4L60E comes with multiple pinion plates. Not only does it provide strength to the engine but also allows it to withstand the torque. 4L60E paved way for future transmissions by improving on the technology and build pattern. 

During 1997, electronically mastered variants of shift control became common in two-wheelers as well as four-wheelers. 4L60E was then commonly seen in Corvette, manufactured by Chevrolet. Additionally, almost all versions were fitted with this transmission type. Senors were often used to determine gear shifting with an increase in vehicle speed.

What is 4L80E?

4L80E is one of the top-rated transmissions. It is compatible with different power levels and multiple engine combos. It was manufactured around the sixties and remained in production till 2013. 4L80E transmission comes with four gear shifts and higher resistance to torque.

Initially, there were some issues with the older model. But as advancements were made, it became more and more compatible. It was made cooler attraction-wise and swifter, accommodation-wise.

Applications by some popular car companies

  1. Rolls Royce
  2. Hummer H1

It has an elongated overdrive and longer length than its predecessor. Still, it is heavier than the previous version. Since drivers can reprogramme the transmission according to their liking, it was an instant favorite.

The core reason why individuals prefer 4L80E is its reliability and compression power. Apart from luxury vehicles, the transmission can also be found in motorhomes and buses. The manufacturing company provides multiple customizations to fans and automobile geeks.

Some of the widely known brands to use 4L80E are Bentley, Jaguar, and Aston Martins. Automatic transmissions like 4L80E are inspired by TH400. They resemble its shape, power, and durability. Transmission’s outward appearance is one of the major factors for their luxury appeal and usage.

Transmission Veterans often argue whether 4L80E was a class apart from 4L80E’s predecessors. Some are of the belief that earlier versions were only slightly inferior. While many believe it to be the transmission revolution of the sixties.

Main Differences Between 4L60E and 4L80E

  1. 4L60E Transmission comes with four forward gears and a single reverse gear. 4L80E comes with only four forward gears.
  2. 4L60E is a more advanced range of transmissions. 4L80E is an inferior range of transmission compared to its successors.
  3. 4L60E is used in many Chevrolet cars. 4L80E is used in Rolls Royce and Bentleys.
  4. 4L60E is much lighter in weight than its predecessor. 4L80E is heavier and tougher than its successors.
  5. 4L60E is remembered for its torque power converter and design. 4L80E is remembered for its craftsmanship and visually attractive structure.

Conclusion

4L60E and 4L80E are vintage transmissions that revolutionized the automobile industry. They can be regarded as the forefathers of the transmission industry. Many vehicles owe their existence to these transmissions.

Both of these transmissions were widely in use during the golden age of the automobile industry. Their advanced variants were constantly updated and at times they were simultaneously in use. Many consider them as the backbone of the transmission industry.

Automobile geeks often favor 4L60E as their favorite transmission but their respect for 4L80E cannot be refuted. Collectors have a special preference for 4L80E. However, Formula race drivers used 4L80E as their go-to transmission.

Visually, 4L60E and 4L80E are regarded as equally creative and efficient. One is regarded as the epitome of craftsmanship while the latter is often associated with technical brilliancy.

There is no doubt that 4L60E withstands a greater torque power than 4L80E transmission. This is mainly due to advancements in gear technology. The better shift ratio of 4L60E transmission is widely acclaimed.

Conclusively, the automobile industry has always held these transmissions in high regard. Without these veterans, no one can imagine the current development in the industry. Often citing them as an inspiration for transmission enthusiasts.
