How To Drain Torque Converter 4l60e


When your car is having serious performance issues, it’s in your best interest to do some research about it. If you want to run better engines, you have to know how to drain the engine of all the fluids!

There are several reasons why you would need to service or upgrade an engine part like a torque converter. One reason is because it becomes contaminated as you use it, which could cause damage to the engine or loss of power. Another is due to fluid leaking out, which will waste money.

This article will go into detail about one type of torque converters and what can be done to make them work more efficiently. It also goes into detail about symptoms that indicate this system needs help, and what tools can be used to fix it. So, let’s get started!

Torque converter basics

A torque converter is a device that helps transmit energy from the motor to the wheels. As electricity flows through a wire, it creates magnetic fields. A solid metal object such as a bolt creates a surface area where these two opposite ends meet, creating a source of static (or steady) electric charge.

When another object with a lot of electrons comes close, the two collide, cancelling each other out slightly. But instead of disappearing completely, both objects pull away from each other, leaving a gap.

Check the torque converter clutch

The first step in draining your old torque converters is to check it out! You can do this by taking off the cover, or you can use our easy tool here.

If there are no drag marks on the blades then we’re good! These take time to make so don’t worry about it for now.

It’s important to remember that even if the engine isn’t running, the torque converter will still be spinning. This could cause damage to the transmission or dry-clutch friction bearings. Make sure these are both sound and working properly before replacing them.

Dry clutches also need regular fluid changes, so keep an eye on the level! We recommend changing the oil every 5,000 miles.

Hopefully one of these tips helped you get through the process of removing your current torque converter! If you have any questions feel free to leave a comment below, talk with us in the Shop online chat, or give us a call at 855-363-6620.

Change the oil

Changing your car’s engine oil is one of the most important maintenance tasks you will do to your vehicle. Engine oils play an integral part in ensuring your car or truck will run smoothly and for a long time!

Oil helps prevent corrosion by acting as a barrier between the metal parts of the engine and the combustion gasses that enter the engine. Corrosion can cause damage to both the engine components and the internal passageways of the engine. This could result in broken down engines, expensive repairs, or even failure of the engine completely!

The quality of the engine oil you use makes a big difference in how well it performs its main function, which is protecting your engine from corrosion. Oils with higher viscosity (stiffness) are better at this than those with lower viscosities.

As mentioned before, when changing the engine oil we recommend using synthetic motor oil because they contain additives designed to improve the performance of the oil. These additives include antioxidants and detergents that help protect the engine form oxidation and contamination, respectively.

Synthetic oils also clean up the engine much more effectively than regular vegetable oil due to their composition. When replacing the old engine oil, make sure to add an equal amount of new oil so that you don’t risk having poor engine performance due to low levels of oil.

Check the pressure in the transmission

A fluid that does not contain enough alcohol will show lower than normal pressures when pressed. If this happens, you can be sure that there is no torque converter stall happening!

This doesn’t mean that there isn’t any drag or friction caused by the torque converter though– it just means that it has lost some of its efficiency due to lack of hydraulic engagement.

Make sure the fluid is new

It is important to make sure that whatever type of engine you are working on, there are no loose fluids anywhere! If you notice liquid coming out of the top or side of the torque converter, do not pour it down the drain as this could cause damage to the transmission.

Instead, use a syringe to determine if the fluid is old or newer. An older fluid may be all burnt up so it will not come out of the shift solenoid, but if the fluid is newer then get it as soon as possible because the longer the fluid sits around the more likely it is to burn up which would prevent the converter from engaging.

To avoid having to buy a new fluid, make sure to check both dry clutch plates for cracks and look under the cover plate in the converter for any debris.

Check the transmission fluid

It is important to check your vehicle’s fluid level, as this can make a difference in how well your car starts and whether it will function properly while driving.

Most vehicles have an empty engine casing or cowl area that covers the radiator and other engine components. This area is called the cowling.

By looking through the opening of the cowling, you can see if there are any signs of fluid leaking out. If there is no fluid inside the cowling, then it has probably been replaced already.

If however, there is some fluid inside the cowling, then try to determine where it is coming from by inspecting the surrounding areas. For example, if there is fluid dripping onto the floor of the garage, then look under the car for fluid stains there.

Alternatively, if there is fluid coming off of the drain plug at the base of the old converter, pull it out and see if there is still fluid around it.

Run a diagnostic test

One of the most important things to check when your vehicle is having trouble starting is your torque converter. The engine in cars comes from the combustion process, which requires energy to occur. This energy comes from fuel mixed with air and ignited, producing heat and motion, or kinetic energy.

Your car’s automatic transmission uses this kinetic energy to start moving the wheels, so it can be tricky to determine whether the torque converter is the source of the problem.

If you are experiencing extremely low gas mileage during startup, noise coming from the engine compartment, or fluid leaking out of the torque converter, then it is time to look into replacing it.

Perform a repair

While it is important to drain your engine’s fluid, there is another reason to do this. If you experience squeaking or clanking sounds when moving the vehicle, then chances are that something in the torque converter isn’t draining properly.

This can cause excessive heat which will eventually damage the pump or fins within the converter. In some cases, water may get into the transmission area and cause additional problems such as corrosion or poor performance.

To avoid having to replace the entire unit, check out our guide for how to service your torque converter! You will also need to make sure that any fluid left over has been removed so it doesn’t re-seal the hole it drained through.

Replace the transmission fluid

Changing your oil in an automatic car is tricky, because there are so many parts that make up this system. You have to be careful not to overfill it or drag it down when you drain it, as this can lead to leakage.

There are several types of oils used for transmissions, depending on what ratio of cars they were designed for. The most common type is called 1T5 engine oil, which was made for vehicles with 5 cylinders (1 being a piston going up and down, 2 being two valves per cylinder, etc.). These engines use approximately 3 gallons of oil per change!

Other vehicle makes may use different ratios of their own special motor oils, but none of them are mandatory to work. If you’re ever unsure whether your specific gearbox requires a certain level of oil, do some research and test out a few brands before changing it.
