A BG transmission fluid exchange is a professional maintenance service that replaces nearly all of the old transmission fluid in your vehicle with fresh BG-approved fluid. Unlike a basic drain-and-fill, which only removes fluid from the transmission pan, a BG exchange uses specialized equipment to circulate new fluid through the entire system while pushing out the old fluid at the same time.
This process cleans out fluid from the torque converter, valve body, and cooler lines, resulting in a more complete fluid replacement.
BG Fluid Exchange for Transmission Costs
The cost of a BG transmission fluid exchange generally ranges from $180 to $350. Most standard passenger cars with conventional automatic transmissions fall toward the lower end of this range, while larger vehicles and more complex transmissions are usually more expensive.
Compared to a basic drain-and-fill, which often costs between $90 and $160, a BG exchange costs more because it replaces a higher percentage of fluid and often includes additives.
Factors That Affect the Price
Several factors influence how much you will pay for a BG transmission fluid exchange. Vehicle type plays a major role, as trucks, SUVs, and vans require more fluid than compact cars.
Transmission design also matters, since CVTs and dual-clutch transmissions use specialized fluids that cost more than standard automatic transmission fluid.
Labor rates vary by region and shop, and vehicles with difficult access points or higher fluid capacities will naturally cost more. Additionally, some service centers bundle cleaners, conditioners, or warranties into the price, increasing the total cost but adding value.

What’s Included in the Service
Most BG transmission fluid exchange services include the full exchange of old fluid, BG-approved replacement fluid, and optional additives such as cleaners or conditioners.
Some shops also perform a visual inspection for leaks and may check transmission operation before and after the service. It is important to confirm what is included, as a lower price may reflect a partial exchange or fewer additives.
Is a BG Fluid Exchange Worth the Cost?
For many drivers, a BG fluid exchange is worth the extra cost compared to a standard fluid change. Because it replaces nearly all of the old fluid, it can improve shift quality, reduce heat, and extend transmission life.
This is especially beneficial for high-mileage vehicles, vehicles used for towing, or those experiencing rough or delayed shifting. Considering that transmission repairs or replacements can cost several thousand dollars, the price of a BG exchange is often seen as a preventative investment.

Recommended Service Intervals
Most technicians recommend performing a BG transmission fluid exchange every 30,000 to 60,000 miles, depending on driving conditions and manufacturer guidelines.
Vehicles used in stop-and-go traffic, hot climates, or heavy-duty applications may require more frequent service. Always check your owner’s manual to ensure a full exchange is appropriate for your specific transmission.

How a BG Fluid Exchange Works
During the service, a technician connects BG’s exchange machine to the transmission cooler lines. As the engine runs, the machine introduces new transmission fluid while removing the old fluid in equal amounts.
In many cases, a BG transmission cleaner is added beforehand to loosen varnish and deposits, followed by a conditioner to protect seals and improve shifting. The entire process typically takes between 45 minutes and 1.5 hours, depending on the vehicle.
Final Thoughts
The cost of a BG transmission fluid exchange reflects the thoroughness of the service, the quality of the fluid, and the expertise required to perform it correctly.
While it is more expensive than a simple drain-and-fill, the added protection and performance benefits can make it a smart long-term maintenance choice for drivers who want to keep their transmission running smoothly and avoid costly repairs.
