Signs that it's Time for a Transmission Flush

Signs that it's Time for a Transmission Flush

A general recommendation is that transmission fluid gets exchanged about every 30,000 miles. However, it's worth referring to your owner's manual to see the mileage intervals that are specified for your particular vehicle. But there are also some symptoms that suggest you should soon get to the shop for a transmission flush regardless of how long it's been since you last had this service done. Considering that transmission issues can quickly become very expensive to repair, it's always best to be proactive about addressing issues as soon as they arise. Here's a look at five signs that your car needs a transmission fluid flush.

Slipping Gears

If contaminants in transmission fluid obstruct the fluid's flow, then there may be a reduction in hydraulic pressure to the point that there is insufficient power to keep your vehicle in gear.

Trouble with Shifting

Old, polluted transmission fluid may lead to gears shifting too slowly or too quickly. For optimal shifting in both automatic and manual transmissions, it's important that your transmission has a proper level of clean fluid.

Grinding Noises

If your transmission is making grinding sounds, you'll want to pull over to a safe spot and check your transmission fluid while your engine is still running. Healthy transmission fluid typically has a reddish color. If your transmission fluid looks or smells burnt, then you'll want to take action to figure out the underlying problem.


There's a good chance you could benefit from a transmission flush if your vehicle briefly stalls after you put it in gear.


If contaminants block the flow of transmission fluid, your vehicle may begin to lunge or surge. Hopefully, a transmission flush is all that you'll need to resolve this issue.

Without proper maintenance, a transmission could fail. If your transmission has failed and you need a replacement, be sure to order from a reputable supplier.
