Transmission fluid leaks can be hard to detect at first, but certain symptoms can help you identify the issue early.

✅ Signs of a Transmission Fluid Leak:

Red, Pink, o r Brown Fluid Under the Car – Fresh transmission fluid is red o r pink, while old fluid turns brown o r dark.
Burning Smell While Driving – If the transmission fluid leaks onto a hot surface, it may produce a burnt odor.
Low Transmission Fluid Levels – A in fluid levels, noticeable during routine checks, can indicate a slow leak.
Rough o r Slipping Gear Shifts – Low transmission fluid can cause delayed gear shifts o r jerky movement.
Puddle o r Stains in the Parking Spot – If you notice consistent fluid stains under your car, it might be from the transmission.
🔹 How to Confirm a Transmission Fluid Leak?

Place a cardboard sheet under the vehicle overnight to check for leaks.
Check the fluid color and smell—if it’s reddish o r brown and doesn’t smell like engine oil, it’s likely transmission fluid.
Use a flashlight to inspect under the car, especially near the transmission pan and cooler lines.
