Transmission flushings and oil changes

The most effective flushing for automatic transmissions

Tim Eckart - Method

Complaints like slow gear engagement, choppy change, vibrations and other problems of transmissions are well known to technicians of car repair shops.

Unfortunately, smooth gear shifting is not always possible because metallic abrasion, debris and contamination can never be avoided entirely. Over time, they accumulate and deposit within the automatic transmission and impede and diminish the functions of the sensitive control valves. As a result the flow of oil can be obstructed.

The metallic abrasions spread through the whole system and affect the lubrication, which in turn can lead to increased wear in aluminum components. All this can cause serious problems while switching gears and shorten the life of the automatic transmission significantly.

Only through a „full automatic transmission oil change“ can deposits and contaminants be removed from the system. However, this is usually very labour-intensive and costly. Due to different designs of some transmissions, it is not possible to replace the oil completely. For example, when there is no drain plug on the torque converter. In this case, the oil is removed but leaves behind a lot of contamination in the converter, which in turn leads to impurities within the oil system. As a result transmission problems occur again.

But there is a solution to this problem

The flushing machine from Tim Eckart

The user-friendly flushing system by Tim Eckart, not only replaces the oil, but washes and cleanses the whole automatic transmission with a special cleaner. The oil flush system combined with the cleaner, makes a powerful duo in removing quickly, easily and efficiently all contaminants that can cause malfunction and performance of an automatic transmission.

To remove these contaminant deposits, the cleaning liquid is inducted prior to the flushing operation. Subsequently, the vehicle is operated in various gear speeds for 15 minutes time, to ensure an even distribution of the cleaner within the transmission. After that, the flushing system is connected to the oil cooler.

Afterwards,  the oil can be collected in a container of the flushing system. Before adding the new oil, the oil pan is cleaned and a new oil filter is installed.

The Tim Eckardt flush system pumps the new transmission oil, with a 12 volt pump, directly from the oil cans into the transmission oil reservoir.

It is this easy and fast that an automatic transmission oil change including a cleaning can be carried out. 

Flushing vs. Oil Change

Benefits of flushing compared to oil change

  • Almost all deposits, caused by abrasions, are removed and rinsed out
  • Problems caused by impurities are eliminated
  • Costly repairs of the automatic transmission can be avoided
  • After an oil change, approx. 40-50% of the old oil remains in the transmission
  • Use of a special cleaner
  • Customers report a better shift feeling after a flushing
  • Partially even lower fuel consumption
  • Almost complete oil change by using the flushing device
  • No oil mixing of new and old oil during flushing

A hint from us

The manufacturer often speaks of a longlife gear oil, for which no service interval is planned.


However, we recommend changing the complete oil every 60,000 - 80,000 km.

Please note: This device does not replace an oil cooler flushing device!

  • Please consider that a transmission flushing may take between 3-4h.
  • For longer distances, the transmission and the oil may have to cool down a little before the workers can start their work. The cooling time also depends significantly on the outside temperature.
  • After consultation, you are welcome to bring your vehicle to us on the previous day and pick it up the following day.
  • If you need a transport to the next train stop "Ubstadt-Weiher" or "Stettfeld-Weiher" please let our staff know. We are happy to do this for you.

    You will find the connections HERE.
  • Within walking distance is also the town centre with a bakery, which invites you to spend some time while waiting.
