The past 20 years have seen a considerable improvement in the transmission world. 4L80E transmission is a four-speed overdrive transmission which is one of the best overdrive transmissions. This transmission is a descendant of the proven and popular TH400 transmission.
It is known to offer better power flow, is rugged, and has much more potential for power capacity as compared to any other overdrive transmission on the market. This is also why more and more people are searching for 4L80E transmission rebuild kits online.
Simply put, right from a design and engineering perspective, it’s a superior transmission with powerful combinations. Though it is not for everyone, it is best for people who plan to make serious power.
These transmissions can be found behind 4.3 to 8.1-litre gas engines and 6.5-liter diesel engines. They are also electronically controlled and sit inside a die-cast aluminium housing.
Identifying 4L80E transmission
One of the significant clues in identifying 4L80E transmission is the electronics that clip onto the driver’s side of the transmission. The transmission is also larger than TH400 as the overall length is 32 inches.
To the benefit, there are various ways to go about acquiring one of these transmissions. The most accessible and inexpensive route is to buy a brand new or rebuilt one off the shelf, which can be purchased through several companies offering a warranty.
Problems That Often Occur In This Transmission
Transmission Fluid Leaks
Leaks are a common vehicle problem that can be avoided with due care. Once you inspect your car, try to determine where the leak is coming from. A common area for leaks is the front seal, which is located near the torque converter. The other areas are the rear seal, pan gasket, transmission lines and the electrical connections or sensor area.
Lock Up Torque Converter Problem
The torque converter, when working correctly, should allow the lock-up clutch to apply pressure to the converter and transfer the correct torque to the transmission. This connection between the engine and transmission can only occur properly if the torque converter works well. If the torque converter fails, it can result in overheating and torque converter issues.
If you have ever suffered a problem that can only shift into reverse or second gear, you might be in limp mode. This mode is triggered when the computer is trying to protect itself from the transmission. Experts advise having an OBD2 scanner, which can be highly helpful and tell you whether a sensor is malfunctioning or the transmission has a severe problem.
Remember that the clutch starts to burn or wear out when the transmission fluid gets low. This can result in the wearing of the drum. In addition, overheating frequently happens when the car is pushed to perform for longer on high torques.
If you encounter any problem of the above kind, don’t delay connecting with an expert. I prefer buying a 4L80E transmission rebuild kit and getting over the continuous problems.
If you are interested in getting your transmission fixed, you might want some dedicated help. Don’t hesitate to connect with experts that can help you with your step-by-step needs.
The 4L80E is designed for longitudinal engine configuration and is not for everyone. Some owners experience problems, but if subjected to immediate attention, the 4L80E transmission serves well and long.
