Will A Transmission Flush Hurt My Car?

There have been many controversies on whether or not the use of transmission flush could affect your car. First, understanding what transmission flush is important. Also, you need to know when your car needs a transmission flush. All these and many more will be explained in detail in this post. 

What Is A Transmission Flush?

A transmission flush involves the connection of your transmission to a professional-grade machine. The primary aim is to completely flush the transmission fluid from your vehicle. Running a solution through the lines until it is clean. It then fills up your system with new fluid.

Many manufacturers indicate the most appropriate solution. And so car manufacturers recommend against the use of transmission flushes, why? This is because during the process these machines could be improperly connected. Improper connections can lead to block or pressurize the wrong passages inside the transmission and cause damage.

 Some machines could technically run the transmission pump dry. It’s because they can remove more fluids than they add back in. Flush machines, unless cleaned out between different vehicles, can also pump a small amount of the wrong fluid into your transmission. Even if there’s only a small chance of your transmission being damaged by a flush machine, why risk it? 

Now, will a transmission flush hurt my car? Well, as earlier mentioned a transmission flush (using an external machine) may not be good for your transmission. This at times could be inimical to your car.

Are Transmission Flush Necessary?

A transmission flush is necessary for an automatic transmission’s longevity. It helps in the improvement of the fuel economy and may help validate warranties. Now you see that the key to longevity for any machine is routine maintenance. Most importantly, the statement of fact is especially vital for cars, trucks, and SUVs. This navigates the highways and byways daily. 

Nowadays, you’d see that most people could have their engine oil changed, radiators flushed, and tires rotated. Well, one routine service could often be overlooked in a transmission flush. Yes, it is common for car owners to ask if a transmission flush is necessary.

Having a transmission flushed every 30,000 to 50,000 miles could be crucial. Especially if you drive a car with an automatic transmission.

Can Flushing Transmission Cause Problems?

Here is what happens during transmission flush. A simple method to replace the transmission fluid (usually at home) is by draining out the old fluid and pouring in new fluid. However, this method tends to leave residues in line which can compromise the new fluid. A more trusted method is when your mechanic uses a machine attached to your vehicle transmission pump.

In doing so, he gently flushes out the old fluids while pumping new fluids simultaneously. If the line is particularly dirty, the mechanic may run a solvent. Through this, the debris would be cleared out of the line. This will also be done before introducing a new fluid.

There are speculations on whether transmission flush can cause more harm than good. It could be by dislodging debris along the transmission line. However, this could happen when the auto shop is using a machine that forces the fluid back through the system. 

 More so, if your vehicle has gone beyond 100,000 miles, having a transmission flush done could cause transmission failure. Your mechanic may advise against it.

How Do I Know If My Car Needs Transmission Flush?

Though there might be no upset in the transmission presently, it is good practice to get your transmission fluid flushed. This should be done after every 30,000miles or two years. However, you may observe some signs, which could suggest you get a transmission flush. 

Note, it should be done regardless of how since you got one. If not done on time, minor transmission problems may worsen and lead to more expensive repairs. It’s always best to get to the shop at the first sign of trouble at this stage. Here’s a look at five signs that it’s time for a transmission flush. 

i. Gears Slipping

If your transmission fluid is old and dirty, then contaminants could block the fluid’s flow. Consequently, the reduction in hydraulic power would be the result. And as a result, there might be insufficient power to stay in gear.

ii. Issues with Shifting Gears

You’re most likely to have shifting gear or gunked-up transmissions if you use a standard or automatic transmission. Therefore, the proper amount of clean fluid should be used.

 iii. Stalling Out

 If there is a stall out when you put in the gear, then you may be able to remedy the problem with a transmission flush.

 iv. Lunging

Luge or surge could be made possible if contaminants block the flow of transmission fluid. Thereby, getting a transmission flush will hopefully subside these symptoms.

 v. Grinding Sounds

If you notice a grinding sound, the right to do is to pull it off. Then check your transmission fluid with the vehicle still running. When the transmission fluid is reddish, then it is clean and healthy. Darker fluids are a sign that a transmission flush could be needed.

How Much Does A Transmission Flush Cost?

Proper maintenance of all the fluids in your car is integral to ensure it runs smoothly. And a transmission flush is not exempted. But what has the cost of a transmission flush cost?

Well, the actual price depends on where you go and the quantity of fluid you need. It could often be calculated through the range at which your car is gagged. In general, you will likely need to pay anywhere from $100 to as much as $400.  

Should I Get A Transmission Fluid Change?

Transmission fluid is important for lubricating the parts of your transmission. And it reduces wear and tear caused by friction and heat. While changing your transmission fluid won’t damage the condition of your transmission. If you haven’t been changing it frequently enough, you may discover that your transmission slips.

Every vehicle is different, so it’s no surprise that every car has different requirements for how often transmission fluid should be changed. 

To determine whether or not you should change fluids, wipe the dipstick on a white paper towel. Afterward, observe the color of the transmission fluid. If the fluid is bright pink, your transmission fluid is new and does not need to be changed. Also, if the fluid is a light brown with a hint of pink, your transmission fluid will need to be replaced. 

If your transmission fluid hasn’t been changed in a long time, it will appear a very dark brown color. It may even have metal particles floating in it, indicating the transmission is damaged.
