Spotting and Fixing Transmission Fluid Leaks: What You Need to Know

Your car has a way of telling you when something's wrong. It could be a strange smell, slow shifting, or a check engine light. Another sign is fluid leaks. A transmission fluid leak can be scary because it might lead to expensive repairs or even a broken transmission. Transmission fluid is like oil for your gearbox. It keeps the moving parts cool and smooth. Most people don't think about it until there's a problem. Modern cars don't need fluid changes as often, maybe every 60, 000 to 100, 000 miles, depending on the car and how you drive. If you check the fluid level and it's low, act fast. A sweet smell and red puddles on your driveway are signs of a leak. Driving with low fluid can damage your transmission. Repairs can cost a lot, so it's good to know the common causes of leaks.One common cause is a worn-out transmission pan. It's a metal container that holds the fluid. It can last a long time, but aggressive driving or rust can damage it. If you see fluid under your car, check the pan. If it's cracked or damaged, replace it. You can do it yourself or take it to a pro. When replacing the pan, check the gaskets too. They prevent fluid leaks and can wear out over time. If they're not installed right, they can cause leaks. Installing a new gasket is easy, but make sure to do it correctly. Another cause of leaks is damaged fluid lines. These lines keep the transmission cool by circulating fluid. Extreme temperatures and road debris can cause cracks or ruptures. If your transmission is shifting hard or overheating, check the lines. If you find a small crack, you can fix it temporarily with hose clamps, but see a mechanic soon.
