Does Your Vehicle Need a Transmission Flush?

A transmission flush involves removing all of the old, dirty transmission fluid and replacing it with new fluid. New transmission fluid provides maximum protection against wear and tear to critical components, such as gears and bearings. In general, car manufacturers typically recommend doing a transmission flush every 30,000 to 60,000 miles. However, you should defer to the specific recommendations for your car. Even if it’s not time for a regularly scheduled transmission flush, the following problems can indicate that your car needs one soon.

Jumping or Surging

Have you noticed that your vehicle tends to surge forward or fall backward for no apparent reason? The culprit could be dirty transmission fluid. Transmission fluid is essential for the smooth operation of the gears. If the vehicle’s movements are inconsistent, a car mechanic will check the transmission.


Similarly, a vehicle with dirty transmission fluid may exhibit delays in movement. After you put the car into gear, it may stall for just a second or two before moving. A transmission flush can help fix this problem.

Grinding Noises

Any abnormal change in your car’s noises is cause for concern. If the transmission fluid is contaminated with sludge and dirt, the car may produce a grinding noise. You can check the level of the transmission fluid while your car is still running. If the fluid doesn’t appear to be leaking, then it’s probably dirty and needs to be flushed out.

Oxidized Fluid

Another way to check whether your car’s transmission fluid needs to be flushed out is to see if it’s been oxidized. You may be able to detect oxidized fluid just by smelling it. Oxidized fluid will smell acrid, similar to burnt toast. You can also use the paper towel test. Place a couple of drops of transmission fluid on a clean paper towel. Wait several minutes and check the drops. Does the fluid disperse or stay in droplet form? If it doesn’t disperse across the paper towel, the fluid has oxidized and needs to be flushed.
