How a Transmission Flush Works

Transmission flush

A transmission flush procedure is generally performed using special pressurized equipment that is connected to a vehicle.  Cleaning solvent is then forced back into the transmission removing deposits of old transmission fluid from parts and components.  The cooling lines, cooler, converter and other parts are all thoroughly cleaned.

One of the benefits of this procedure is that all of the transmission fluid is removed and replaced.  This is different from a fluid change in which only some of the fluid is replaced.  A simple fluid change cannot remove all of the built up deposits that accumulate over time as is done during a flush.  Also, some of old fluid remains potentially contaminating the new fluid that is put in.

Transmission Flush Good or Bad?

There is considerable debate as to whether transmission flush procedures can be harmful to a vehicle and is a transmission flush good or bad for your automobile.  While many mechanics and experts agree that having a clean transmission will extend the life of a transmission, it is thought by some that the flushing procedure may not be the best way to achieve a clean transmission.

One common thought is that the process, which forces liquid back into the transmission in the opposite way of the normal fluid flow, could potentially damage components or block tight passageways.  When fluid is forcefully pushed back into the transmission, chunks of debris can be dislodged and possibly block narrow channels or one-way valves.  When new fluid is put back in, these blockages can inhibit the normal flow of fluid through the transmission causing lubrication issues.

Nonetheless, many car manufacturers and dealerships contend that these procedures are not harmful at all and help revitalize auto transmissions.

Transmission Flush Good or BadIs a Transmission Flush Necessary?

Ultimately it is wise to consult the manufacturer owner’s manual and follow the guidelines outlined within.  If the manufacturer recommends a transmission flush, it is probably advisable to have the service performed.  However, it is true that not all manufacturers recommend this service at frequent intervals.  It is not uncommon for flushes to be performed only every 100,000 miles.

Be very careful when taking your automobile to quick oil change or lube service stations.  These types of maintenance shops might be quick to recommend a transmission flush unnecessarily and at intervals that are more frequent than necessary.  Hopeful the information contained within this site will help answer the question – is transmission flush good or bad for your vehicle?

    I can understand changing out the fluid but several car manufactures recommend refilling with the same transmission oil. Is transmission oil compatable with other oils. I have a bmw and was told to go by the plate on the bottom of transmission which i did. the oil only costs 18/liter or about 144 for 4 liters. is dextron iii compatible?

    T-tech tranny flush units do not back flush. The pump in the transmission pumps the old fluid out and pushes the new fluid in. I have flushed well over 2000 transmissions with 98% customer satisfaction.We do not use chemicals,we flush with the proper atf for that car or truck. Its simple,you open a cooler line and hook the machine in like its a very large cooler. Start the engine and let the pump in the tranny pump out the old fluid displacing the new fluid back into the tranny.
