4T65E Transmission – What You Need to Know

If you are like most drivers, you probably have no idea what kind of transmission you have. Outside of automatic versus manual, there is not much mainstream knowledge about the ins and outs of car transmissions. Depending on what car you drive, there is a good chance you have a 4T65E transmission inside of your car. But what exactly is the 4T65E?

About the 4T65E Transmission

The 4T65E is type of automatic transmission made by General Motors. This particular auto transmission is designed to be used with transverse engine builds. All that means is that the transmission sits perpendicular to your car’s range of motion. However the transmission still sits inside the engine bay of your car.

This series of transmissions contains four forward gears, making it a best fit for front wheel driving vehicles. The 4T65E is also controlled electronically which we can tell by the E at the end of the name.

Believe it or not, the first iteration of this transmission was actually the 4T60. But with some mechanical upgrades and new electronic controls, the transmission developed into the 4T65E.

When Was The 4T65E Built?

GM first introduced the 4T65E transmission in 1997. The old transmission was phased out to allow for better torque conversion and improved reliability.

In 2000 all 4T65E transmissions were upgraded with new valve bodies. These could be found in cars such as the Pontiac Grand Prix.

In 2003 another upgrade was made to improve internal electronics and better shifting capabilities.

4T65E Transmission Problems

Although the 4T65E is considered one of the hardest working transmissions on the road, it comes with its own problems. Like most transmissions, wear and tear over time will cause the transmission to deteriorate.

As long as you shift your car properly and do not abuse your gear shift, your transmission should have a long life.

In the event you do notice issues shifting then you may want to get your 4T65E transmission checked out.

When getting your car inspected, make sure to have the mechanic look into your transmission. This way you can avoid issues in the future and prevent transmission fluid leaks.
