Beware the Dangers of Automatic Transmission Fluid Additives

Being proactive and doing all you can to maintain your car's health is admirable for sure. But as the old saying goes: if it sounds too good to be true it probably is. That's what we think of when it comes to transmission fluid additives that claim to stop leaks and fix transmission issues. These types of additives are not only misleading but should be avoided if you want your transmission to run better in the long run.

Being proactive and doing all you can to maintain your car’s health is admirable for sure. But as the old saying goes: if it sounds too good to be true it probably is. That’s what we think of when it comes to transmission fluid additives that claim to stop leaks and fix transmission issues. These types of additives are not only misleading but should be avoided if you want your transmission to run better in the long run.

 

Do These “Fix All” Additives Work?

While these automatic ‘transmission fix’ additives DO impact your vehicle, it’s not the magic cure the advertisements promised. In short, they DO NOT WORK.

 

Why Would Someone Use an Additive?

Since these products are aimed at vehicles with automatic transmissions, it’s important to understand these systems. Eventually, areas of the automatic transmission will fail, just like any other part or machine especially when it’s used as often as a transmission.

A transmission is a complicated apparatus, and in order to work correctly, it uses seals that contain pressures and keep fluids in place. Over time, these rubber seals become rigid or hard and when the pressure is not contained properly it can cause the fluids leak. These additives propose to stop leaks and make your transmission run better, and if you don’t know how your transmission works, they SEEM to do just that.

 

If These Additives Don’t Fix the Problem, What Do They Do?

This is the tricky part. The additive will immediately (in a day or so) work to soften and expand these rubber seals chemically. This allows them to expand and stop the pressure and fluid leaks. Your car or truck will seem to work better and give the illusion that the problem has been solved. Wrong!

What really happens is that the transmission’s seals start to swell and usually do not stop doing so until they are worn away or have stretched to the point that they are not effectively holding their shape anymore. If these seals fail, your transmission has a COMPLETE FAILURE. Not only is this a costlier issue, it this usually happens only months after the “transmission fix-all” additive has been used.

 

What is the Right Way to Handle These Problems With The Transmission?

First, know that these seals in your transmission becoming hard and brittle is a normal occurrence. While having a transmission specialist check it out is a good idea, there’s no real cause for alarm when this happens. When the cars are cold, their transmission seals are more brittle. However, once the car warms up, the seals soften and work better. You have a “grace period” of sorts, to get this issue checked out and diagnosed by an experienced technician. This is why we recommend getting your transmission checked out as soon as it sticks or delays to engage.

Ultimately, these fix-it additives act more as a temporary solution for this issue.  These transmission seals must be replaced eventually and while it’s not something anybody wants to pay for, it’s much more cost-effective in the long term to have it done when the transmission still functions. Waiting until the transmission fails can be expensive as a complete system replacement is one of the most expensive repairs your vehicle can have.
