A 4L80E transmission has an overdrive ratio of 25% and a final drive ratio of 3.42 or 3.73. These two versions are similar, though the latter is more powerful. They both have the same GVWR limit, so buying a used 4L80E is a good way to save money. However, be careful: you might not be able to tell the difference between them without a closer inspection. You should be aware of the common problems associated with used transmissions.
This type of transmission was made with expense in mind. The internal parts were built with high quality steel and aluminum. The transmission is electronically controlled. The housing is made of die-cast aluminum and is durable. You can find a 4L80E transmission for sale near me by using a national directory. The transmission has a 440 lb-ft. torque rating and a maximum load capacity of 18,000 pounds. You can also buy a rebuilt 4L80E transmission for sale near me from a remanufacturer.
The 4L80E transmission is a 4-speed automatic gearbox that uses the same architecture as the TH400. The TH400 is the predecessor of the 4L80E, but it used different components. It included a lockup torque converter and an extra forward gear. This served as a fuel economy overdrive, and it was made with a stronger 32-spline output shaft. It also had a Transmission Control Module (TCM), which could learn the driver's style and preferences.
When purchasing a 4L80E transmission, you should be aware that the 4L80E is larger than the 4L60E. As such, it's easy to misplace one. Purchasing a 4L80E transmission brand-new is the best option for most drivers. You can find a high-quality unit online or in your local classifieds. The downside is that you might have to pay a lot for a new one.
A 4L80E transmission has many benefits over its predecessor. Its lockup torque converter allows you to shift gears quickly and smoothly without a manual shift.

If you're unsure of what you need, you can search for a used one on the Internet.
When looking for a used 4L80E transmission, it's important to consider the potential problems. A 4L80E has a limited number of gears and a limited range of torque. In addition, it's not possible to replace a transmission that is overdrive. It needs a controller to be fully functional. In these cases, you should consider buying a used 4L80E transmission instead.
