What is 4t80e?

The 4T80E is a four-speed automatic transmission developed by General Motors. It was first introduced in 1993 and is typically used in front-wheel drive vehicles with higher torque applications, such as luxury sedans and some SUVs.

The transmission features an electronically controlled torque converter clutch and overdrive gear for improved fuel efficiency. It also has a heavy-duty design to handle higher torque outputs, making it suitable for larger vehicles.

The 4T80E is known for its smooth shifting and durability, but it can be prone to issues such as solenoid failures and worn internal parts with higher mileage. Regular maintenance and fluid changes are important to keep the transmission running smoothly.

Overall, the 4T80E is a reliable and capable transmission option for vehicles requiring a high-torque automatic transmission.
