Upgrades That Will Make Your 4L60E Transmission Perform Better

Upgrading to a high-performance transmission can transform your car. Still, you don't need to spend money to get the benefits. There are plenty of inexpensive upgrades to make your 4L60E transmission perform better every time you get behind the wheel. If you're looking for more power, these are the upgrades you should consider:

Shift Kit

A shift kit is one of the most common upgrades for most automatic transmissions. It improves the speed and effectiveness of gear changes, making your car more efficient, responsive, and fun to drive. A shift kit also reduces premature wear on your 4L60E transmission, making it last longer and perform better over time.

Transmission Cooler

Transmissions use fluid pressure to deliver power to the driveshaft from the engine. The fluid gets hot as it does this job, and too much heat can cause damage. A transmission cooler transfers some heat away from the fluid and into the air, so the fluid stays in better condition. This reduces friction and wears throughout your transmission, letting it work more smoothly and last longer at higher temperatures.

Torque Converter

The torque converter allows your vehicle to shift without stopping at each gear. The engine spins a turbine inside the torque converter and transmits power through three different "stator" plates. These stator plates allow the turbine to spin faster or slower than the engine speed, which gives us smooth shifting between gears in a 4L60E transmission. If you have an old or worn-out torque converter, you will notice that your vehicle does not shift as smoothly as it should, so consider replacing it in that case.

Separator plate

The separator plate is a thin piece of metal between the low/reverse band and the direct clutch drum located at the rear of the case. A weak or worn separator plate can allow these clutches to interact, resulting in erratic lockup behavior. There are upgraded plates available from various sources.

Closing thoughts

We hope this article acts as your guide to enhancing the performance of your 4L60E transmission with upgrades. These well-chosen components will help you get into other gears faster and more smoothly, with less effort on the part of you or your tires. The results? A better vehicle for a smoother ride for everyone aboard. These upgrades are easy to install, and most can be done yourself.
