Why It’s Important to Change Your Transmission Fluid (and How Our New BG Machine Helps)

October 21, 2025

At Joe’s Slinger Service, we take pride in keeping your vehicle running strong — and that includes your transmission. It’s one of the hardest working systems in your car, and it needs clean, healthy fluid to do its job.


Over time, transmission fluid breaks down. Heat, friction, and debris slowly wear it out, causing it to lose its ability to protect internal parts. When that happens, your vehicle can start to shift harder, slip between gears, or even suffer long-term damage.


What Transmission Fluid Does


Transmission fluid acts as both a lubricant and a coolant. It keeps all those moving parts inside your transmission working smoothly and helps carry away heat. When the fluid gets dirty or starts to break down, it can’t do either job very well. That’s when you start to notice performance issues — or worse, face an expensive repair.


How Often Should You Change It?


Most vehicles need a transmission fluid service every 30,000 to 60,000 miles, but it really depends on how and where you drive.

If you do a lot of towing, drive in stop-and-go traffic, or deal with extreme temperatures, you might need it sooner.


Not sure when yours was last changed? We can check the condition of your fluid and help you figure out the right schedule for your vehicle.


Our New BG Transmission Fluid Machine


We’re excited to now offer transmission services using our new BG Transmission Fluid Machine. This advanced system allows us to completely exchange your old, worn-out fluid with fresh fluid — not just a partial drain and fill.


That means cleaner operation, better protection, and smoother shifting — all backed by BG’s trusted technology and products.


Keep Your Transmission Running Strong


Changing your transmission fluid is one of the simplest and most effective ways to keep your vehicle reliable for years to come. It’s an affordable service that can help you avoid major transmission repairs later on.
