what to know:
what is a transmission flush?
A transmission flush is a procedure designed to remove old automatic transmission fluid (ATF), along with any accumulated sludge and grime, from your vehicle’s transmission. The goal is to replace it with fresh fluid. ATF is crucial for cooling and lubricating your automatic transmission. Over time, the fluid can collect foreign particles that hinder these functions, leading to increased friction and heat. Eventually, these particles can form sludge deposits that interfere with shifting and acceleration. This service is available at participating locations.
What are the Benefits of a Transmission Flush?
A transmission flush helps to maximize the lifespan and performance of your automatic transmission, which is one of the most expensive components to replace. However, it does not resolve any preexisting transmission issues.
Is a Transmission Flush the Same as Changing Transmission Fluid?
No, changing transmission fluid and flushing the transmission are two distinct services:
- Transmission Fluid Change: This process replaces 50-60% of your transmission fluid. The transmission pan is drained without special equipment, inspected, and cleaned. The transmission filter is replaced, and new fluid is added, resulting in a mix of old and new fluid.
- Transmission Flush: This procedure replaces 100% of your transmission fluid and purges accumulated particles and deposits from the entire transmission. Fluid is expelled using a cooler line flushing machine or a pump inlet. The transmission pan is inspected and cleaned, the filter is replaced, and a complete batch of new, pure ATF is added.
How Often Should I Flush My Transmission?
Refer to your vehicle owner’s manual to find the manufacturer’s recommended intervals for transmission flushes for your specific model. Common intervals range from every 30,000 to 50,000 miles or every 3 to 5 years.
How Often Should You Replace Transmission Fluid?
If you’re not having full transmission flushes, a typical ATF change interval is every 3,000 miles or every two years. Again, consult your vehicle’s manual for specifics.

Signs It’s Time to Flush Your Transmission
Here are some indicators that you may need to flush your transmission:
- Dark Red or Brown Fluid: Fresh ATF should be a vibrant red color. If the fluid on your dipstick appears dark, it indicates that foreign particles have accumulated in your transmission fluid.
- Transmission Slipping: This occurs when there is poor coordination between the engine and your vehicle. If the engine engages but your vehicle responds sluggishly or out of sync, it could be a sign of ineffective ATF or a leak.
- Unusual Shifting Sensations or Noises: If you notice changes in how your transmission shifts, either in feel or sound, this could indicate ineffective ATF or a potential leak.
At Monty’s we include a visual inspection of your transmission fluid as part of every comprehensive vehicle check.
how long does that take?
A trained mechanic can complete a straightforward transmission flush in approximately three to four hours using a commercial flushing machine or pump inlet. In contrast, a transmission fluid change typically takes around 30 minutes. Keep in mind that you’ll need to allocate extra time for any additional services performed concurrently.
would a transmssion flush hurt my vehicle?
A compromised transmission should not undergo a flush. Applying excessive force during the flushing process can dislodge debris, causing it to settle in areas that may lead to further issues.
If you’re uncertain about the best course of action for your transmission, consult any Monty’s Auto technician for expert advice tailored to your specific situation.
