A transmission flush is a procedure to remove old automatic transmission fluid (ATF), sludge and grime from a vehicle’s transmission and replace it with fresh fluid. The purpose of ATF is to cool and lubricate your automatic transmission. Over time, transmission fluid collects foreign particles that can interfere with these functions -- causing your transmission to generate more friction and heat. Eventually these particles can build up into sludge deposits in your transmission and interfere with shifting and acceleration.* Available at participating locations.↩
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.
Is a transmission flush the same thing as changing transmission fluid?
Changing transmission fluid and flushing the transmission are two different services:
- Transmission Fluid Change - Replaces 50%-60% of your transmission fluid. Your transmission pan is drained without special equipment, inspected, and cleaned. The transmission filter is replaced and new fluid is added, leaving a mixture of old and new fluid.
- Transmission Flush - Replaces 100% of your transmission fluid and purges accumulated particles and deposits from the entire transmission. Fluid is expelled from your transmission using a cooler line flushing machine or a pump inlet. The transmission pan is inspected and cleaned, the filter replaced. A complete batch of new, pure ATF is added.
