How to Identify Transmission Fluid Leaks in Your Vehicle

Regular transmission leaks can affect the working of overall vehicle. They have to be cared for immediately. They are one of the most complicated and expensive part of a car. This is because they have many moving parts working together. That is why; if one part suffers then other suffers as well. This can easily lead to full system failure.

So it would be beneficial for you to know how to deal with a transmission fluid leak. This article is for signs, identification and prevention of such leaks.

Signs of a Transmission Fluid Leak

  1. Most common sign of a fluid leak is a pool of liquid under your vehicle. This fluid can either have a sweet or a burnt smell. One should not ignore it, if it is a common sight with their vehicle.
  2. Another sign is rough or delayed gear shifts. The gears will not work seamlessly of there is low transmission fluid. Delay and jerk in gear shift will be a common thing.
  1. Burning smells are also common. It is clear sign of overheating. This sharp and unpleasant smell comes out from different vents of the car.
  2. If the transmission fluid leaks, it can affect the engine as well. And the ‘check engine’ light may get lit. you may think an engine issue is there but it may be related to transmission,
  3. Low fluid levels on the dipstick can confirm the leak. When you check and see it’s below the minimum line, its time to fill that up again.

 Locating the Leak: Where to Check

  1. Start by checking the area beneath the transmission pan. This is where most leaks occur. The pan holds the fluid and is sealed with a gasket that wears out over time.
  2. Inspect the transmission cooler lines. These carry the fluid between the transmission and radiator. If they’re old, they can crack or become loose.
  3. Look around the input and output shaft seals. These are round seals where the driveshaft connects. If they are worn, they can let fluid escape.
  4. Check the fluid reservoir or dipstick tube. It might seem like a small thing, but even these parts can leak.
  5. Transmission fluid leaks can also come from sensors or fittings. Some vehicles have sensors that monitor pressure or temperature. These parts can leak if the O-rings or gaskets fail.

How to Check for Leaks Step-by-Step

  1. Let your car sit overnight on a clean and leveled surface. Then check for fluids of any kind on the surface.
  2. You can also put a utensil below the car to collect the fluid. This way you’ll be able to know how much fluid is being leaked. Otherwise a piece of paper of cardboard can be used as well.
  1. Pop the hood and pull the transmission dipstick. Wipe it clean. Insert it again and check the level.
  2. Inspect around the transmission pan. Look for wet spots or stains. If you see fresh fluid, the gasket may need replacing.
  1. Follow the cooler lines and check for wet or oily spots. Run your fingers along the lines to feel for moisture.
  2. Inspect the area where the driveshaft connects. If the seal is leaking, you’ll see fluid flung around nearby parts.
  3. Look at the bell housing. This is where the engine and transmission meet. A leak here can mean a bigger issue like a failed front seal.
  4. Use UV dye if the leak is hard to find. Add it to the transmission fluid and use a UV light to spot the glowing trail.

 When to Seek Professional Help

  1. Any type of constant drip of massive pool of fluid is a clear indication of a huge crack.
  2. If you smell burning fluid while driving, call a shop. You may not have the skill to deal with such situation.
  3. If the transmission slips or shifts hard, stop driving the vehicle. Get it towed to a mechanic. Driving with low fluid can wreck the transmission fast.
  4. If the dipstick shows a low level more than once, even after topping it off, it’s leaking somewhere. A trained eye can find and fix the problem.
  5. If you see fluid coming from the bell housing or torque converter area, don’t try to fix it yourself. That repair requires removing the transmission.

 Preventing Future Transmission Leaks

  1. Keep up with regular maintenance. Check your transmission fluid every month. It takes just a minute and can catch issues early.
  2. Change the fluid and filter at the recommended interval. Old fluid breaks down and loses its ability to protect the parts.
  3. Replace the pan, gasket and seals if you notice wear. These rubber parts don’t last forever. This small step can easily prevent future transmission fluid leaks.
  4. Avoid aggressive driving. Hard shifts and high heat break down fluid faster and wear out seals.
  1. Keep the transmission cool. If you tow heavy loads or drive in hot areas, consider adding an external cooler.
  1. Check for loose bolts or fittings. Vibrations from driving can shake things loose over time. Tighten what you can and watch for drips.
  2. Use the right type of fluid. Always follow the manufacturer’s guide. The wrong fluid can cause damage and leaks.
