How To Flush a Torque Converter?

The torque converter is seen as part of the transmission system. It is a key aspect that controls the torque from the engine into the transmission system.

When the transmission fluid in the torque converter is bad or contaminated, it will affect how the torque converter works. When this happens, the transmission system as a whole is affected.

To prevent further damage to your transmission system, you should flush it following the right procedure, which we will look into.

What does a Torque Converter do?

There has been much confusion about what the torque converter actually does, and many confuse its function with the transmission system. For a better understanding, let’s look at how torque converters came into use.

Manual transmission systems are linked to the engine with the help of a “clutch.” The clutch transmits torque from a rotation driving motor that turns the wheel to the transmission.

Without the clutch, your manual vehicle cannot come to a complete stop without damaging the engine.

However, the automatic transmission does not make use of clutches. Instead, they have what is called a torque converter.

The torque converter is a fluid coupling mechanism that allows the engine to spin or function independently without transmission interference. In cases where the engine is idling, the amount of torque is reduced with the help of the torque converter.

When are you required to flush a Torque Converter?

Once you notice the sign listed above and you have had a proper diagnosis leading to contaminated fluids, you must have the torque converter flushed. To do this, you must first prepare your vehicle for the procedure. It will include draining the torque converter.

So, how to drain the torque converter with no drain plug?” As we know, many torque converters do not have drain plugs.

Below is how to do it:

  • Park your vehicle in a secured, leveled area and ensure the parking brake. Pop the hood open and allow the transmission cool. It should take about 30 minutes.
  • Check the total fluid capacity. You can do this with the help of your vehicle’s manual.
  • Locate the cooling line and place a bucket beneath it. You can find the cooling line connected to the radiator or a smaller radiator.
  • Disconnect the transmission cooling and direct the fluid to the bucket or pan to collect the fluid.

Once you have successfully drained the torque converter, you can then move on to flush the system. To do this carefully, follow the steps below:

  • Start the engine and immediately switch the transmission to neutral. At this point, fluid continues to flow from the transmission cooling line. Ensure that it is draining into the drain pan or bucket.
  • Using a transmission fluid, you can continue flushing the torque converter with mineral spirits.
  • Place a funnel in the opening of the transmission dipstick tube. Pour in your mineral spirit or transmission fluid. Ensure to pour at the same rate at which it is draining.
  • Shift the gear. You have to carry out the process with the help of a friend. Do this until you have shifted through all gears and switched back to neutral.
  • If you use mineral spirit, ensure that all the spirit is drained out of the cooling line while still on neutral. Then go on to add transmission fluid.
  • Turn off the engine once the full amount of transmission fluid has been used.
  • Reconnect the transmission line and restart the engine.
  • Check the level of transmission fluid using the dipstick or fill port.

Before we move on, we must look into the question, “Will a torque converter fill itself?The answer is yes. The fluid will circulate once you start the engine and automatically fill the torque converter.

How long does it take to flush the Torque Converter?

Flushing your torque converter is a straightforward process that should not take much time. It should take between 30 minutes to an hour to have the procedure done.

How long this procedure will take depends on many factors. For instance, if this is your first time flushing your torque converter, it would take more time when compared to a person who has done this before.

Also, the extent of fluid in the transmission system and other underlying problems you face increase the duration of the process. Giving it to a professional will be much faster because of a torque flush machine.

How much does it cost to flush the Torque Converter?

A torque converter flush costs between $100 and $300, depending on many factors, like the model of the vehicle, where you will have the flush done, and more. It is, however, more affordable to have the procedure done by yourself.

In addition, having a professional carry out the procedure will cost an additional $100.

People hitting the search box “torque converter flush near me” may visit any professional mechanic Shops nearby, and they will do it for you in no time.

Final words

In closing, flushing a torque converter is an essential maintenance task for your vehicle’s health. By following the correct procedure, you can effectively eliminate contaminants, improve performance, and prolong the life of the converter. Remember, consistent maintenance is key to a long-lasting and efficient torque converter.
