What Are the Symptoms of Bad Transmission Fluid?

Knowing the symptoms of bad transmission fluid is crucial for vehicle maintenance. Here are the most common signs:

Why Is Transmission Fluid Important?

Transmission fluid is vital for your vehicle’s performance. It lubricates the moving parts, cools the transmission, and ensures smooth gear shifts. Without proper fluid, the transmission can overheat or suffer from excessive wear.

1. Locate the Dipstick: Most vehicles have a transmission fluid dipstick near the engine.
2. Check Fluid Level: Ensure the fluid is at the recommended level.

4. Smell the Fluid: It should not smell burnt.

Changing transmission fluid depends on your vehicle’s make and model. Generally, it should be changed every 30,000 to 60,000 miles. Consult your owner’s manual for specific recommendations.

2. Drain Old Fluid: Remove the transmission pan and drain the fluid.
3. Replace Filter and Gasket: Install a new filter and gasket to prevent leaks.
