#4l80e transmission manuals

From 1991 through 1993, a few early 4L80E messages had minor problems. The 4L80E and the 6L80E are reliable transmissions that are strong. That includes the cables, torque converter, electrical harness with the control module, and gearbox. You can buy the conversion kit at for a little over $4,000 and receive everything you need. The 4L80E is a better improvement than most older automobiles since it does not have sophisticated electronics.įor older Corvettes and most other GM cars made before 2000, you can purchase a 6L80E conversion kit. The pricey and sophisticated electronics are the primary problem. It is not only the 6L80E transmission’s size, which is a significant issue, that prevents it from simply fitting into all vehicles. Furthermore, regardless of engine horsepower, the 6L80E is doomed to failure without appropriate tuning and calibration. The 6L80E, on the other hand, has a more contemporary gearbox and is considerably more vulnerable to wrong TCM tuning and engine-to-transmission calibration. On the other side, the 6L80E can securely handle up to 650 wheel horsepower. The 4L80E can handle up to 750 wheel horsepower with simple modifications before needing hard component upgrades. Additionally, the four-speed can withstand a bit of energy than the six-speed, even though the numbers 80 in both the 6L80E and 4L80E signify the same strength rating. Some of the cars that got the 4L80E include the Hummer H1, Chevy trucks, vans, or even Rolls Royce, Bentley, and Jaguar. If you want one for an off-road vehicle, that is something else to consider. The 6L80E sits lower since it is also taller. However, because of its much larger diameter, the 6L80E can only be installed in earlier vehicles if it requires body changes. The 6L80E, however, is shorter overall, measuring just over 29 inches as opposed to 32 for the 4L80E.

The 6L80E will inevitably be larger than the 4L80E since it has two more gears.

Therefore the 6L80E is a better option in that situation. However, nobody will notice the additional 17 lbs when driving daily.

And while a 17 lb difference may not seem like much, it might matter in drag racing.Ī six-speed gearbox needs to be updated since you will not utilise the two overdrive speeds much in drag racing. The 6L80E weighs 195 lbs, compared to 178 kg for the 4L80E. Unfortunately, the 6L80E is somewhat heavier due to the two additional gears. The 6L80E is a much better choice for everyday driving as a result. The engine will probably live longer with a 6L80E since it is under less strain with lower gear ratios. The two last ratios are overdrives, allowing you to continue cruising on the highway at a low engine speed and improving fuel efficiency. Suppose you have a truck that provides you with significantly greater acceleration and higher hauling capability. Remaining on gears, the 6L80E can get away with having two more gears, which results in substantially shorter gear ratios. That the 6L80E quickly appeared in sports vehicles like the Corvette and Camaro. The 6L80E became a much stronger competitor to the Europeans with six front gears. Thus, the 4L80E received two more gears in 2005 to become the six-speed 6L80E.

Some of the cars that got the 4L80E include the Hummer H1, Chevy trucks, vans, or even Rolls Royce, Bentley, and Jaguar.Ī four-speed, however, was going to take longer to cut as automatic transmissions gained popularity in the early 2000s with the arrival of automated manuals and double-clutch automatics. Given that the 4L80E was predominantly employed in heavy-duty applications, the four gears made even more sense. Four packs were formerly considered sufficient for the 4L80E, which was introduced in 1991. The number of gears is hence the primary distinction between the two systems. Differences Between 4L80E and 6L80E Number of Gears However, the 6L80E has shorter gear ratios due to the two additional gears, which improves fuel efficiency and ride quality. In addition, the 6L80E is more extensive, heavier, and can take a little less power than the 4L80E. A 6L80E has six forward gears, compared to a 4L80E’s four. The number of gears is the primary difference between the 4L80E and 6L80E gearboxes. Even while they fundamentally resemble one another more than they vary from one another, the distinctions that do exist are essential to take into account if you want to get the most out of your car. Nevertheless, one will be superior to the other in certain instances. This holds for the 4L80E and its replacement, the 6L80E, and these transmissions are excellent choices. One of the most durable automatic gearboxes on the market is one that General Motors is known for producing.
