How Is a BG Flush Performed?

BG Flush Fluid Exchange Service is a quick, efficient way to change the transmission fluid in your car, truck, or SUV. The process removes all of the old fluid and replaces it with fresh, clean transmission fluid in as few as five to seven minutes, placing it among the fastest and most efficient flushes in the automotive service market.
It is essential that your engine remain in tip top shape so that it will produce power for miles and miles to come. And it is vital that you keep the brakes on your car in excellent condition. After all, they are insanely important to your safety and that of your passengers. But the ability to produce power — both to move and to stop — is completely irrelevant if you cannot transfer that power to your wheels. That is the job of your transmission: to take the energy from your engine and transmit it to the wheels.
Now, if you drive a stick shift manual transmission rather than an automatic, you do not need to worry about transmission fluid. But if you have one of the majority of vehicles sold in the U.S. (whether it be a FWD, RWD, 4WD, or AWD), you have an automatic transmission. And if yours is an automatic (more than ninety percent are), you need to consider changing your transmission fluid as part of routine maintenance for your vehicle.

Some manufacturers suggest that the transmission fluid they install from the factory should last the lifetime of their vehicles. That is fine. But many automakers recommend replacing it every so often. Not as frequently as you might change your motor oil, but, like any of the fluids and filters on your car, it is expected on a regular basis nonetheless. Manufacturers call for transmission fluid changes as frequently as every 45K miles (even sooner in some harsh driving conditions) and as infrequently as 90–120K miles (assuming they want it changed at all). Most transmissions are not “owner serviceable” these days. Many do not even include a trans oil dipstick anymore. Rather, it is necessary to take your car to a trained technician with special tools to have the fluid checked and replaced.
When it is time to replace your transmission fluid, you have two service options: drain and fill your transmission or a fluid flush. There are several reasons you should consider BG Flush Fluid Exchange Service for your vehicle, including:
BG Flush will dissolve deposits in the transmission
Replace all of the fluid in the transmission and remove deposits
Contains additives to condition seals, inhibit oxidation, and improve shifting
When you simply have the fluid drained and refilled, the old fluid is not entirely removed. In fact, much of the fluid that is contained in the torque converter is never exchanged. A technician removes the trans oil pan and allows the fluid to run out.
But much of the old fluid stays behind and mixes with the new, contaminating it from the very start. BG Flush Fluid Exchange Service is far more thorough — and it is faster.
But how is a BG Flush Fluid Exchange Service performed on your transmission? Here is a general list of steps that a technician will take to exchange the transmission fluid in your vehicle.
Start your engine and make sure it is up to operating temperature
Check the level of the transmission fluid
Add several ounces of BG Quick Clean for Transmissions to quickly and effectively remove damaging deposits and clean the valve body, filter screen, and other important components in your transmission
Drive the vehicle for fifteen minutes or place it on a lift so that the wheels are off the floor, where the transmission can be shifted through all of its gears allowing the BG Quick Clean to contact all surfaces
Shut off the engine and locate a junction in one of the transmission hydraulic lines where an adaptor can be used to connect the line to the flush machine. The line is separated, the adapter is installed, and the machine is attached by way of the service hoses
With the machine engaged, the engine is started and the system is checked for leaks
Your transmission’s own hydraulic pump begins the fluid exchange immediately by pumping the old fluid into the machines tank. This automatically causes a diaphragm in the tank to exert pressure on the fresh fluid and sends it to the transmission. Because the pressure that goes out is the same as that coming back in, the fluid level in your transmission remains constant. The technician simultaneously shifts gears from within the vehicle to make sure that all of the cleaner and old fluid is purged.
The exchange is complete when the technician notices a differential in fluid pressure between the inlet and outlet hoses. The fluid level in the transmission is verified and a special conditioner is added to the new fluid.
Finally, the pressure in the system is relieved, the service lines and adapters are disconnected, the transmission line(s) reattached, and the vehicle test driven for validation.
The above steps may differ from vehicle to vehicle, but the idea is the same: your old, dirty fluid is gently rinsed from your transmission while fresh fluid replaces it.
Drivers often fear the loss of a transmission because it is very expensive to replace one. Sometimes, a manufacturer’s defect can be the problem. But, unless you find yourself in the unlikely event that your car turns out to be a lemon (falling under your state’s lemon laws), you will not be protected if your transmission dies because of plain old neglect. If you want your vehicle to last 200K miles or more, make sure to give it the routine preventative maintenance that it deserves, including
BG Flush Fluid Exchange Service. Check with the manufacturer for the service schedule, usually found in your owner’s manual. And remember to ask about a courtesy check the next time you visit your local repair shop.
