Can You Use Stop Leak Products in Your European Car’s Transmission?

No Comments

If you’ve spotted a small transmission fluid leak under your European car, have you been tempted to just throw some stop leak products at the problem and be done with it? Star Motors European knows that is a bad idea, and here’s why.

Damage Is Still Damage

The bottom line is that damage to the seals in your transmission is still damage. Stop leak products aren’t going to undo any torn or ripped seals that are letting transmission fluid leak out. Typically how these products work is by trying to restore the brittle rubber seals in the transmission. But that doesn’t add material where none exists any longer.

You Might Experience New Leaks

Something else that’s important to understand is that you can actually experience new leaks from using stop leak products. Because the products are trying to make the seals fill gaps again, the main side effect is that the seals soak up the product and swell. In areas that don’t need that to happen, new gaps can form which creates new leaks. That just adds to the problem.

This Isn’t a Lasting Repair

As if you didn’t have enough bad news about these stop leak products, there’s more. This isn’t a lasting repair at all. Assuming that you do experience benefits and the leaks do stop, that’s not a true solution. The products will wear off and remember that the seals are still damaged, so they’re still in need of replacement. In a pinch, they might help you to have an extra few days to get the car to the shop, but that’s about it.

You Risk Creating a Bigger Problem

Ultimately what you’re looking at is having possibly created a bigger problem for yourself and for your European car’s transmission. You may need more seals replaced than you did initially and if you’ve tried using stop leak products several times, you’ve wasted both time and money on something that didn’t work at all. That doesn’t make sense and it doesn’t do anything good for your car at all.
