Transmission Flush Service

Although not as common in the automotive world as an oil change - transmission flushes serve an important purpose.


A transmission flush usually involves connecting your transmission to a professional grade machine to completely flush the transmission fluid out of your vehicle. Running solution through the lines until they come out clean, it then fills your system with new fluid.

A transmission fluid change, on the other hand, simply drains the fluid with gravity. A change usually does not drain all of the fluid, but does allow you to replace most of the old with fresh transmission fluid. Both services are helpful and can extend the life of your transmission.


These are warning signs that you may need a transmission flush  - slipping gears, delay in movement, problems shifting gears or grinding noises.

You should be aware that if the vehicle is displaying these symptoms, your dirty transmission may have already caused bigger problems.

Sometimes the fluid level is an issue, but if the fluid level of the transmission is acceptable, your vehicle probably needs a transmission flush.


Ultimately it is best to consult your manufacturer owner’s manual and follow the recommended services and guidelines provided. Many manufacturers recommend a transmission flush every 30,000 miles or 2 years.

However, not all recommend this frequently – some suggest a flush only every 100,000 miles, and others don’t recommend a transmission flush at all. Sometimes, if your car is having trouble, you may need a transmission service between the recommended intervals.
