Fluid Leaks and their Causes



If you’ve backed your car up or drove your car forward and noticed a little spot on the ground, then there are probably a million things running through your head. We automatically think of worst case scenario, so you get out and check what it is. If it’s a little reddish spot that smells a little sweet, then you’ve got yourself a transmission fluid leak. There is no need to worry, because there may be a way for you to fix this yourself. Before going over the ways to fix a transmission fluid leak, we should go over what may have caused yours.


This first cause that may be the reason for your leak is your transmission pan. Transmission pans are susceptible to damage over time. The wear and tear could be too much for your individual pan to handle, so you should check for any holes/punctures in your pan. While you’re at it, check for any loose bolts or drain plugs. Those being loose could contribute to the amount of leakage coming from your vehicle. While driving, your car is constantly coming into contact with small amounts of debris. Doing this could be the cause of your punctured pan. The bolts coming loose over time are something that tends to happen to all bolts. There may be no need to replace them, so simply tightening should do the trick. That same debris that put a hole in your pan could have also punctures the fluid line. Driving at high speeds on the freeway is the most likely time for you to come in contact with this loose material. Heat may also damage your fluid line, so having regular maintenance on your car is highly recommended.


The pan and fluid lines aren’t the only thing that could potentially crack under the constant use of your car. Pan gaskets can occasionally be the reason for your leak, so it is worth checking if any of the reasons above weren’t the cause of your leak. If your gasket hasn’t been replaced in a while, it can grow cracks that allow transmission fluid to seep through. If your gasket wasn’t placed or aligned properly, it can begin to warp and allow that same fluid to come through. Once warped, the gasket won’t seal properly and will continue to be an issue. Pan gaskets can be purchased fairly cheap at your local auto parts store.


If you are unfortunate enough to have your torque convertor as the reason behind your leak, then I have some bad news. If your torque convertor is cracked and begins to leak transmission fluid, there is no choice for you other than to take it to a shop. Unless you have the proper training and experience fixing cars, I would not recommend you tackle this job on your own. It is always good to have a professional in your area that your trust, so I would advise you to get online and find one right away. The longer you hold out and let your car leak, the worse the damage may become.
