If you’ve been driving your vehicle and have noticed its automatic transmission slipping recently, then you’ve come to the right place! In this article we cover a variety of products used to help remedy issues with an automatic transmission slipping and help you with selecting the one that is right for you.

Why is My Transmission Slipping?

There are many reasons for automatic transmission slipping. If left for too long, your transmission could become damaged. It’s very important to recognize signs of an automatic transmission slipping so it can be addressed as soon as it starts happening.

One of the simplest reasons that could cause a transmission to slip, or act irregular, is the lack of fluid. It’s very important to make sure you maintain the fluid not only in your transmission, but everywhere on the vehicle where lubrication is required. If your vehicles transmission is low on fluid, make sure to top it off, and check for leaks. If you have found a leak, be sure to check our our article on additives that can help restore seals and gaskets on your transmission and stop leaks by clicking here!

In time, transmission fluid and lubricants in general will break down. This is due to the life of the fluid as well as heat and other elements. It’s important to make sure you keep up with changing your vehicles transmission fluid as bad fluid can cause automatic transmission slipping. Refer to your vehicles user manual for change intervals as well as fluid type.

Another potential cause of slipping transmissions could be from vanish and other buildup on the internals of the transmission. There are many small passages and valves inside of your transmission that can become blocked or sticky as buildup occurs. many additives will help clean this buildup out and add lubrication to internal components. A clean and well lubricated system means properly moving components and no hanging up to cause shifting and automatic transmission slipping issues.
