What is a transmission fluid flush?
A transmission fluid flush is a maintenance service for a vehicle’s transmission system. During a flush, the old transmission fluid is removed and replaced with new fluid, which helps to maintain the transmission’s performance and lifespan. The process typically involves using a machine to pump out the old fluid, while simultaneously pumping in new fluid. The flush is typically more comprehensive than a simple drain and refill, as it aims to remove all of the old fluid and any debris or contaminants that may have accumulated over time. However, it’s worth noting that not all vehicles require a transmission fluid flush, and it’s important to consult the vehicle’s owner’s manual and a qualified mechanic before deciding on any maintenance services.
Is a transmission flush the same thing as changing transmission fluid?
The services of changing transmission fluid and flushing the transmission are distinct:
A transmission fluid change involves draining around 50%-60% of the fluid by removing the transmission pan, replacing the filter, and adding new fluid, resulting in a mixture of old and new fluid.
On the other hand, a transmission flush replaces 100% of the fluid and removes all accumulated particles and deposits throughout the transmission by expelling fluid using a cooler line flushing machine or a pump inlet. The transmission pan is inspected and cleaned, the filter replaced, and a complete batch of new, pure automatic transmission fluid is added.
What is a transmission flush good for?
A transmission flush helps maximize the lifespan and performance of your automatic transmission — one of the most expensive vehicle parts to replace. It does not help with preexisting transmission problems, however.
How often should a transmission fluid flush be performed?
Consult your owner’s manual to determine the recommended transmission flush frequency for your specific vehicle model, typically ranging from 30,000-50,000 miles or every 3-5 years.
For regular automatic transmission fluid (ATF) changes, the common interval is every 3,000 miles or two years. Refer to your manual for guidance.
For assistance in choosing the appropriate procedure for your vehicle and creating an ATF maintenance plan that fits your needs, budget, and schedule, reach out to Bradley’s Auto.
What are some signs that I need to check my transmission fluid?
Signs that indicate the need for a transmission flush include dark red or brown fluid on the dipstick, transmission slipping, and different shifting feel or sound. If you bring your vehicle to Bradley’s Auto, we can also perform a visual inspection of your transmission fluid. It’s crucial to have any transmission issue checked out promptly, as it can be costly to replace the transmission. Addressing a small problem early is advantageous.
How long does it take to flush a transmission?
A commercial flushing machine or pump inlet can facilitate a basic transmission flush, which a qualified mechanic can complete in 3-4 hours. Meanwhile, a transmission fluid change can be done in around 30 minutes. Allow extra time for any accompanying services.
