Your car’s transmission system is one of the most essential and complicated components of your vehicle, so it’s not surprising that related issues are fairly expensive to fix. The most effective way to avoid extensive repairs is routine maintenance at an auto service shop.

One step of the checkup should be a transmission flush, which involves the replacement of old, contaminated fluid for better lubrication and smoother operation. Modern automatic transmissions are so efficient that drivers hardly notice the car is shifting gears, but transmission fluid remains as crucial as ever. Below are some red flags that it’s time to call a mechanic for an appointment.

When to Schedule a Transmission Flush

1. Unusual Sounds

While driving, listen for strange sounds like grinding, thumping, or whining as you shift gears. Pull over and check the level and color of your transmission fluid as recommended by your owners manual—brown or black means the fluid is burnt or contaminated and needs to be changed. Apart from odd noises, pay attention to sensations like vibrations, shaking, or thudding when adjusting speed. Have an auto service professional inspect for any underlying issues as well.

2. Slipping Gears

Operational issues are troubling indicators of dirty fluid, so be on the lookout for these as well. The transmission is designed to maintain gears, and if it shifts on its own, this impairs your ability to control deceleration and acceleration. Slipping gears can be traced to debris or contaminants, which may obstruct the flow of transmission fluid in the system.

3. Difficult Shifts

Vehicles with an automatic transmission may seem like they’re resisting to changing gears or have difficulty getting up to speed. Stick-shift vehicles are even more sensitive to worn-out transmission fluid, and it’s not uncommon for them to get stuck in gear when the fluid needs replacing.

4. Delayed Engagement

Another indicator of contaminated transmission fluid is a noticeable lag in movement after stepping on the gas pedal and putting it in gear. When your vehicle pauses for a few seconds before moving, it’s likely that dirt and contaminants have blocked proper fluid flow throughout the system.

5. Sudden Surging

If you notice jerking, jumping, or surging whenever you shift gears, have your vehicle checked at a reliable auto service shop. You might need to schedule a fluid change to flush out dirt and sludge, which may cause the sudden surging backward or forward of your car after changing gears.
