Is It Time for a Transmission Fluid Change?

Many drivers are diligent about regular oil changes but overlook one of the most critical fluids in their vehicle—the transmission fluid. Your transmission is responsible for transferring power from the engine to the wheels, and without clean, properly functioning fluid, that process can break down quickly.

Transmission fluid lubricates moving parts, cools internal components, and helps transmit hydraulic pressure. Over time, this fluid deteriorates and becomes contaminated with metal shavings, dirt, and debris. If left unchanged, it can lead to slipping, rough shifting, or even complete transmission failure.

How Often Should Transmission Fluid Be Changed

There’s no one-size-fits-all answer when it comes to transmission fluid intervals. The recommended schedule depends on your vehicle’s make and model and whether it uses a manual or automatic transmission. Most manufacturers suggest changing the fluid somewhere between 30,000 and 60,000 miles, though some newer vehicles with synthetic fluids can go longer.

If you tow frequently, drive in hot weather, or spend a lot of time in stop-and-go traffic, you may need to service your transmission more often than the average driver.

Warning Signs, It’s Time for a Change

Even if you haven’t hit the mileage limit, your transmission might already be asking for help. Watch for these signs:

Rough or delayed shifting: If your vehicle hesitates when shifting gears or jerks between them, old or low fluid could be the reason.
Strange noises: Whining, grinding, or humming sounds can signal that the fluid is too dirty to protect the moving parts inside your transmission.
Fluid that smells burnt or appears dark: Healthy transmission fluid should be red or pink and have a clean, slightly sweet scent. A burnt smell or brown color means it’s past its prime.
Transmission slipping: If your vehicle suddenly loses power or changes gears unexpectedly, the transmission may be struggling due to degraded fluid.

Any of these symptoms should prompt a fluid check and likely a replacement before more serious damage occurs.

What Happens During a Transmission Fluid Change

A typical transmission fluid change involves draining the old fluid, replacing the filter (if applicable), and refilling the system with fresh fluid of the correct type and grade. This helps flush out dirt and debris and restores proper lubrication and hydraulic pressure.

In some cases, a full fluid flush may be recommended, especially if the fluid has been neglected for an extended period of time. A flush removes more of the old fluid from the entire system, though it’s best done when your transmission is still operating smoothly.

Is a Flush Always Necessary

Not always. In fact, for high-mileage vehicles that have never had their fluid changed, a flush can sometimes do more harm than good by dislodging debris that’s helping worn parts function. That’s why a professional inspection is essential. Our technicians will determine the right service based on your vehicle’s condition and history.

The Risks of Skipping Transmission Service

Transmission repairs are among the most expensive vehicle services. A fluid change is relatively inexpensive by comparison. Skipping it can cause severe wear, overheating, and eventually total transmission failure. In that case, you might be looking at thousands of dollars for a rebuild or replacement.

Regular fluid service helps prevent breakdowns, extends the life of your transmission, and maintains smooth performance.

Your Car Detailing Questions Answered Everything You’ve Wanted to Know About Detailing—Straight from the Pros at The Garage Automotive Solutions

By Jennifer Filzen • June 1, 2025

There’s nothing quite like the feeling of driving a freshly detailed car. It’s clean, polished, and feels brand new—even if you’ve had it for years. But for many Greeley drivers, auto detailing raises questions: What exactly is included? How often should it be done? Is it really worth it? At The Garage Automotive Solutions , we’re all about helping you take better care of your vehicle—not just under the hood, but inside and out. So today, we’re answering your top car detailing questions to help you protect your investment and keep your car looking (and feeling) its best. ❓What’s the difference between a car wash and a detail? A car wash is like a quick rinse and tidy-up. Detailing is a deep clean, restoration, and protection process for your car’s interior and exterior. Think of it like this: A car wash removes dirt from the surface A detail goes beneath the surface—removing buildup, restoring shine, and protecting finishes Detailing can include things like paint decontamination, hand waxing, clay bar treatment, stain removal, leather conditioning, and more. ❓How often should I get my car detailed? It depends on how and where you drive. For most Colorado drivers, we recommend a full professional detail 2–3 times per year , especially if: You park outside year-round You drive in winter slush or summer dust You have kids, pets, or carpool duty You want to maintain the vehicle’s resale value Routine detailing helps prevent long-term damage like faded paint, sun-cracked dashboards, and permanent stains. ❓What’s included in a full detail? At The Garage, we offer comprehensive detailing packages that typically include: Exterior Services: Hand wash & dry Bug & tar removal Clay bar treatment Paint polish & wax or sealant Tire & wheel cleaning Trim and glass conditioning Interior Services: Vacuuming carpets & upholstery Deep cleaning leather & fabric surfaces Dashboard and console cleaning Stain treatment Window cleaning (inside & out) Odor elimination We also offer custom add-ons like engine bay cleaning or ceramic coatings—just ask our team what’s best for your vehicle. ❓Does detailing help protect my paint? Absolutely. Paint protection is essential in Colorado, where your car is exposed to UV rays, road salt, and fluctuating weather. Waxing or sealing your paint after a polish helps: Shield against oxidation and fading Repel water and grime Extend the life of your paintwork Make washing easier and more effective Our detailing team uses high-quality, professional-grade products to give your vehicle that like-new finish—and the protection to match. ❓Is interior detailing really necessary? If you’ve ever spilled a coffee, dealt with road trip snack crumbs, or cleaned up after a muddy hike—you already know the answer. Interior detailing isn’t just about looks. It helps: Remove allergens, dust, and bacteria Preserve your seats, trim, and electronics Maintain a pleasant driving environment (especially during summer heat) Protect your investment for trade-in or resale value We’ve seen interiors transformed from "well-used" to "weekend-ready" in just a few hours.
