Used 4L60E Transmissions: Affordable Solutions for Your Vehicle
4L60E is a four-speed automatic transmission and used in most of the cars back in 1990s. Now a day’s new transmission are being used and 4L60E transmission doesn’t even manufacture anymore. If your car has 4L60E transmission then instead of searching new transmission, you can go for used 4L60E transmission. Used transmission is known for its versatility and can be found in variety of applications; from light weight trucks to cars. Before we dig deep let’s go through with the key specifications:

Now, let’s move on and learn about the features of used 4L60E transmission:
Features of Used 4L60E Transmission
- In this transmission, you will see four forward gears and one reverse gear which allow the balance of performance and fuel efficiency.
- You must know that E in 4L60E is for electronic control. It used a transmission control module to manage the gear shift which varies on various factors like, vehicle speed, throttle position and engine load.
- Used transmission has the capability of learning and adapting the driver habits over time to optimize both the shift point and comforts depending on how vehicle is being driven.
- It even features a lock-up converter which helps in improving the fuel efficiency by reducing the slip between engine and transmission at high-speed.
- Its fourth gear function as an overdrive reduces the engine’s RPM for the better fuel efficiency while driving on highway.
- The design of this transmission is very modular which includes various key components such as its repairing and upgrades are straight-forward.
These were the feature of used 4L60E transmission; now let’s move forward towards its working to understand more about the used transmission.
How Does Used 4L60E Transmission Works?
Shifting Mechanism
It uses a combination of hydraulic pressure and electronic signals for engaging or disengaging the gears. Then TCM receives the data from various sensors and send signals to solenoids that control the pressure of hydraulic.
Hydraulic System
Now at this stage, transmission relies on hydraulic system to operate. To allow the gears to shift smoothly, fluid pressure is apply on clutches and bands.
Torque Converter
It connects the engine to transmission to allow the smooth engagement and disengagement of power. And the lock-up feature allows for direct connection at high speed and reducing fuel consumption.
Electronic Controls
The sensor monitors all the parameter around it such as, vehicle speed, throttle position and engine RPM. Then TCM analyses this data and control the shifting process, performance optimization, fuel economy and efficiency.
This is the working of used 4L60E transmission. We hope that you a clear understanding about 4L60E transmission.
In The End
In summary, we conclude that 4L60E transmission in used around the 1990s. As it is seen in old model, so its availability is less. But you can replace your current transmission with used 4L60E transmission because of its availability and less price. Here we shared the specifications and features of used transmission along with its working.
