    4L80E Transmission

    The 4L80E transmission is a four-speed automatic overdrive transmission from General Motors. It was introduced in 1985 and was only used in North America. The 4L80E transmission is a 4-speed automatic transmission from General Motors. The 4L80E designation is derived from the powertrain series (4), the number of forwarding gears (8), and the number of reverse gears (0). It was introduced in 1988 for use in rear-wheel-drive cars and light trucks and was later used in front-wheel drive applications.

    The 4L80E is a series of automatic transmissions launched by General Motors. 4L80E was specially designed and created for longitudinal engines. 4L80E series comprised of four forward gears. 4L80Es were only installed in GMC pickups, Hummer H1, commercial vehicles, and vans. It was later taken over by Rolls Royce in the year 1991 and improved after research and testing, it was then used in the Bentley Continental R, and later on other Bentley vehicles and Rolls Royce.

    The 4L80E transmission has a cast iron case with aluminum heads. The input shaft is supported by a single roller bearing, while the output shaft is supported by two ball bearings. It features an overdrive fifth gear and lockup torque converter with an electronically controlled throttle pedal engagement feature that eliminates slip due to accelerator pump loss or engine braking. It is a heavy-duty, four-speed automatic overdrive transmission that was introduced by General Motors in the early 1990s. The 4L80E is used in light-duty trucks, heavy-duty trucks, vans, as well as medium-duty trucks.

    The 4L80E is a derivative of the GM TH700R4 transmission family and shares many of its features. The main difference between the two is that the 4L80E has an overdrive gear which provides more engine braking capability than the TH700R4.

    This transmission is the first to use a torque converter lockup clutch, which locks up the torque converter when the vehicle reaches cruising speed. This technology allowed for more efficient operation of the engine at cruising speeds, improved fuel economy, and reduced emissions.

    The  4L80E transmission is a four-speed automatic transmission. It was introduced in the 1980s as an evolution of the three-speed THM 200-4R transmission. The 4L80E is designed to be the successor to the Turbo 400, but with more power and torque capacity. It is designed to replace the three-speed TH700R4 and the four-speed 4L60E overdrive transmissions. This transmission was first introduced in the GM FWD and RWD truck line-ups in 1988.

    4L80E transmission for Sales

    To know about the origin of 4L80E it is important to know about GM TH400 transmission.

    GM TH400 transmission is a 3-speed automatic transmission. The GM TH400 transmission was introduced in 1965 to replace the Chevrolet Powerglide. It was used in both Chevrolet and GMC trucks and vans, as well as some Cadillacs, Oldsmobile, Pontiacs, and Buicks. The TH400 is a 3-speed automatic transmission with a torque converter clutch that could lock up when needed for better fuel economy.

    The TH400 has a torque converter that provides fluid coupling between engine and transmission, which is located in the engine compartment of the vehicle. The torque converter has a lockup clutch that engages when it reaches operating temperature, providing maximum efficiency at cruising speeds.

    In 1977, the TH400 was redesigned to accommodate a wider variety of vehicles. The new design also had a lower first gear ratio for improved engine braking performance and an increased torque capacity due to the use of stronger gears. This redesign also included an improved shift quadrant that could be installed on either side of the floor console, depending on whether the vehicle had an RHD or LHD drivetrain layout.

    It has been used in many GM vehicles, including the Camaro and Corvette. The TH400 is a three-speed automatic transmission with a torque converter clutch. The 4L80E was introduced in 1988 as the replacement for the TH350, which was used mainly in light trucks.

    The 4L80E is a four-speed automatic transmission with overdrive gear for fuel efficiency and to provide power at lower speeds. It can be shifted manually or automatically with an electronic valve body that uses solenoids to control the actuation of shift valves located within the valve body assembly.


    4L80E TRANSMISSION APPLICATIONS

    The 4L80E was designed to be used in the duty range of the 4L60E and Allison series transmissions, which the TH400 had already found applications in. However, because Allison transmissions were used in medium-duty class (4000 series) trucks, the 4L80E became more popular in Big Block gas and diesel engines.

    Some vehicles in which the 4L80E was used include:

      • Chevy Avalanche
      • Chevy C2500 HD
      • Chevy C3500 HD
      • Chevy Express 2500
      • Chevy Express 3500
      • Chevy Express 4500
      • Chevy K2500 Suburban
      • Chevy Silverado 2500 HD
      • Chevy Silverado 3500 HD
      • GMC Savanna 2500

    Meaning and Sizing

    The “80” in 4L80E refers to advanced torque capacity, whereas “E” stands for electronic or electrical, which basically means that this transmission is controlled by electronic means. Basically, 4L80E is essentially a TH400 with added 25 % overdrive

    The addition of electronic control and overdrive has added over 50 pounds and some width to the transmission but usually, any vehicle that can house TH400 can fit 4L80E too.

    Again, GM has created a masterpiece. 4L80E has left all of us very awe-struck. It is a cleverly designed and executed transmission from General Motors, and not surprisingly has a great record in GM. It has the capability to handle a variety of different powertrains, including diesel and natural gas engines. It also has an electronic control module that monitors the transmission’s performance and adjusts it accordingly.

    4L80E has the ability to operate in any kind of weather condition, it has the ability to shift quickly and smoothly, it has a high torque capacity, and it can handle up to 1000 horsepower.

    The  4L80E transmission is great because it can be used in any kind of weather, it shifts quickly and smoothly, it has a high torque capacity, and it can handle up to 1000 horsepower.
