What Does a Transmission Flush Cost? Is It Worth It?

Whether you're wondering how to fix your car if it doesn't start, or what is going on with your engine, you should know more about your vehicle! So when it comes to your engine care, what does a transmission flush cost, and is it worth it?

What Is The Average Cost Of A Transmission Flush?

The average cost of a transmission flush depends upon the make, model, and overall driving frequency and geological location. The cost could be anywhere between $120 to $250 if done by a professional garage. This cost includes the work for removing old fluid, syphoning or vacuuming the transmission, as well as adding new fluid.

How long does it take to do a transmission flush?

The length of a transmission flush will vary. However, it can generally take around three to four hours. All in all, a full flush service will include the following services: 

  • Flushing out old transmission fluid via vacuum or siphoning system.
  • Further vacuuming to remove dirt, articles of dust, as well as sticky parts from transmission. This makes certain all debris is removed, and doesn't go backwards into the rest of the engine!
  • Filling the transmission with new fluid in accordance with your car's make, model, as well as year and mileage. 

Furthermore, if you have the skill, you can also attempt this process on your own. The time for the flush may also depend upon whether or not your car has a manual, or automatic transmission.

Are Transmission Flushes Worth It?

All in all, when it comes to the life of your car, whether or not a service is worth your time or money is up to you. However, a transmission flush can mean a better working more efficient transmission.

Although the service isn't necessary on all vehicles, it should be done if your car has a lot of mileage on it. Meaning you should have it done between 80,000 and 100,000 miles! Follow your car's owner manual or manufacturers' recommendations.

How Do You Know if You Need a Transmission Flush?

All things considered, there may be a lot of signs pointing towards getting your transmission serviced. Check your transmission fluid first before you go in for a full flush. That way you know the level of pollution in your car's fluid. 

Here are the signs you may need a transmission flush: 

  • Grinding noises when switching gears manually, or your car is moving between gears. 
  • You check your fluids to see if it is low, filled with dust/dirt, as well as sludgy. 
  • You have issues when you are shifting gears.
  • Your engine appears to be slipping gears
  • There is a delay in movement from your vehicle after switching gears.
  • Your car jerks forward rapidly when starting to move (as if you pressed on the accelerator aggressively then quickly released it).

Should I Get a Transmission Flush or Change?

Though they sound very similar, getting a flush or getting a fluid change are two different services.

A full transmission flush is where the all of the fluid is removed, then transmission is vacuumed or syphoned, as well as new fluid being added. The fluid change is where the transmission fluid is drained and the transmission filter replaced. However, this may leave a large amount of old fluid still inside your transmission.
