A well maintained torque converter results in a healthy, functioning transmission. Meanwhile, a bad converter can cause severe damage to your vehicle. Follow our how-to guide below to properly flush a torque converter.
Tools Needed To Flush Torque Converter
You will need to have the following tools on hand to perform this task:
- Funnel.
- Flare tool.
- Bucket for oil drainage.
- Transmission oil.
- Screwdriver.
- Socket wrench.
- Vehicle manual.
Step 1. Disconnect The Transmission Cooling Line
- Refer to your vehicle’s manual prior to starting, as there are two different ways to flush a torque converter.
- Begin by disconnecting the transmission cooling line.
- You can find this line connected to the radiator.
- You may need a flare tool for this portion.
- The engine flex plate can be removed to gain access to the transmission ‘return’ cooling line.
- Types of lines and locations will vary based on the make/model of the vehicle.
- The cooler line and return line are connected to the transmission.
- Check your manual to confirm which line is the return line.
- Disconnect the return line at this time.
Step 2. Start Engine
- Place your bucket or oil pan below the torque converter or transmission cooling line.
- Make sure to keep the transmission in neutral.
- Next, start the engine.
Step 3. Add The New Transmission Oil
- Pour your new oil inside the dipstick of the transmission.
- Allow the oil to drain into your bucket at the same time.
Step 4. Shift Gears
- Try to have an assistant by your side for this step.
- Have your helper slowly shift gears in the transmission through every gear.
- Fresh transmission oil should be poured into the dipstick with the engine running simultaneously.
- Ensure the parking brake is on throughout this process.
Step 5. Test Drive
- Test drive your vehicle for a few miles, then check the transmission oil level once more.
- Check to see if you are satisfied with the current level and that the old oil is completely drained.
Conclusion
Whenever the vehicle is in motion, the internal parts of the converter will spin and turn constantly. The converter comes attached to the transmission, responsible for the vehicle’s motion. This process requires clean oil in order to operate efficiently. Proper maintenance performed on both the converter and transmission will keep your vehicle healthy for years to come.
