Dirty Transmission Filter Symptoms


The transmission in a car or truck regulates the vehicle's engine output. This power is transferred to the wheels, which moves the vehicle. The transmission is a critically important system and can be expensive to repair if something goes wrong. Familiarizing yourself with the symptoms of a dirty transmission filter can help you pinpoint minor maintenance issues before they turn into major repair headaches and will save you money in the long run.

Slipping Transmission
One indicator of a dirty transmission filter is transmission slippage while you are driving. The gearshift may jump, shudder or you may notice rough or uneven shifting. You may also hear a clunking sound. If the transmission filter is clogged, the lubricating fluid will not be able to circulate, causing the transmission to slip.

Leaking Transmission Fluid
If you notice brown or reddish fluid leaking below the engine, it could be transmission fluid. This could indicate a clogged transmission filter. You're your vehicle to a qualified mechanic for service while the leak is still a minor problem.

Dirty or Low Transmission Fluid
You can check the transmission fluid in your car to see if it is dirty or the fluid level is low. Put the car in "Park," open the hood and remove the transmission dipstick. Wipe the dipstick with a clean rag, then re-insert it and remove it again to check the fluid level. If it is low, add just enough fluid to bring the level up to the "Fill" or "Max" line.

Check whether your transmission fluid is dirty by placing a drop on a wet paper towel. Clean transmission fluid may be red or brown; it should not be black or contain metal fragments.
