Signs of Low Transmission Fluid

Signs of Low Transmission Fluid

Transmission fluid is a thick, oily substance that keeps your car’s transmission system lubricated. Often, this oil can leak, so it is advisable to pay attention to your transmission’s fluid level in order to take action if something isn’t right. How? By recognizing the signs of low transmission fluid.

Why Does the Transmission Fluid Level Drop?

The most likely and common reason for the decrease in lubricant level is an oil leak. These leaks are usually caused by a faulty gasket, a loose drain plug, or a crack or damage in the transmission housing.

What are the Signs of Low Transmission Fluid?

If the transmission fluid level is too low, your vehicle will start to show signs of trouble. Here are the most common indicators:

Transmission Slipping

If your vehicle suddenly shifts gears unpredictably or has trouble staying in gear, it may be due to low transmission fluid.

Fluid Leaks

A bright red fluid underneath your vehicle is a strong sign of a transmission fluid leak.

Delayed Gear Shifts

When shifting into drive or reverse, if there is a noticeable delay before the gears engage, there may not be enough fluid pressure.

Overheating Transmission

Overheating Transmission Indicator

The dashboard warning light for high transmission temperature can indicate low or contaminated fluid.

Difficulty with Gear Changes

If gears grind, shift abruptly, or fail to engage, the transmission fluid may be too low.

Fluid Check

Checking the dipstick for fluid level and quality can confirm transmission fluid issues. Cloudy or burnt-smelling fluid may indicate a problem.

How to Check the Transmission Fluid Level

Follow these steps to check your transmission fluid properly:

  1. Start the Vehicle: The transmission fluid should be checked while the engine is running and warm.
  2. Make the Transmission Work: Shift through all gears to circulate the fluid evenly before checking.
  3. Check the Dipstick: Locate and remove the transmission fluid dipstick, wipe it clean, reinsert it, and check the fluid level.

How to Add Transmission Fluid

How to Add Transmission Fluid

Adding transmission fluid is a simple task if done carefully. Here’s how:

  1. Keep the Engine Running: The engine should be on, and the transmission in "Park" with the parking brake engaged.
  2. Consult the Vehicle’s Owner’s Manual: Determine the correct type of fluid and specific instructions.
  3. Pour the Fluid: Use a funnel to add fluid gradually to avoid overfilling.
  4. Check the Fluid Level Again: Shift through all gears again and recheck the level to ensure it's adequate.
