Transmission Services We Offer
We service automatic, manual, and CVT transmissions on all vehicle makes and models.
Transmission Diagnostics (Find the Root Cause Fast)
Transmission problems are not always obvious, which is why accurate diagnostics are critical. If your vehicle is experiencing transmission slipping, hard shifting, delayed shifting, or unusual performance, our team performs a thorough inspection to determine exactly what’s going on. We evaluate internal components, fluid condition, and electronic systems to identify the root cause of the issue. Instead of guessing or replacing unnecessary parts, we focus on giving you clear answers and the right solution the first time.
Transmission Repair Services
Not every transmission problem calls for a full rebuild or replacement. In many cases, the right car transmission repairs are all it takes to restore smooth, reliable performance. We handle everything from CVT and automatic transmission repair to sensor and solenoid replacement, seal and gasket repairs, and internal component fixes — always with a fix-only-what's-needed approach.
Our mechanics bring 50+ years of experience to every job, backed by the certifications to match. You’ll always get our honest assessment, giving you the information you need to make the right call for your vehicle.
Transmission Rebuilds (In-House Experts)
When internal damage is more extensive, a transmission rebuild may be the most reliable and cost-effective option. At Gus’s Gears, unlike other shops, all rebuilds are completed in-house by experienced technicians who understand the details of each system. This allows us to ensure quality, use premium components, and tailor the repair to your vehicle’s exact needs. No outsourcing. No unknown workmanship. Just skilled, experienced, hands-on craftsmanship from ASE-certified technicians. It's a joke around the shop that we can tear down and put back together a transmission with our eyes closed, we are just that good.
Transmission Replacement Options
In situations where a transmission cannot be repaired or rebuilt, a full transmission replacement may be necessary. Our team will walk you through your options, including remanufactured units and warranty coverage. We take the time to explain the differences, costs, and long-term benefits so you can choose the option that makes the most sense for your vehicle and your budget. To give you even more confidence in your new transmission, all our transmission work comes with a nationwide warranty.
Transmission Fluid Service & Flush
Routine transmission fluid changes are one of the most important services for maintaining long-term performance, and here’s why. Transmission fluid keeps your system cool, lubricated, and shifting smoothly. Over time, that fluid breaks down and collects debris, which can cause slipping, hard shifts, or premature wear. Our team will inspect your fluid condition and determine whether a fluid change or flush is appropriate. We always use the manufacturer-recommended fluid and service procedures to protect your transmission and extend its life.
Wondering if you've waited too long for a fluid change? Bring your car in, and we can run a diagnostic to determine what is best for your vehicle. It’s better to find out now than to wait until it’s too late.
Transmission Repair Cost - What to Expect
One of the most common questions we hear is: how much does transmission repair cost? The answer depends on the type of repair needed, the make and model of your vehicle, and the severity of the damage.
Minor transmission repairs can range from approximately $300 to $1,000, while more involved repairs may fall between $1,000 and $2,000. For major issues requiring a transmission rebuild or replacement, costs can range from $3,000 to $7,000 or more.
The most important step is an accurate diagnosis. At Gus’s Gears, we take the time to evaluate your vehicle and explain your options clearly, so you can make the best decision for your situation without pressure or confusion.

Fantastic service and super friendly. Took my 4Runner in for what I thought was transmission issues and they found the real issue that ended up costing me thousands less! Can’t speak highly enough about them.

Gus’s Gears owned and operated by Gus is fantastic! I have sent many friends and family to him for years. He can do anything from regular maintenance to complex repair. He has replaced a transmission on an older Mustang, a motor on an older Dodge, brakes, pads, rotors, oil changes and so much more. He is the only mechanic I go to. I’ve even had cars towed to his shop because I only trust Gus!!!

Transmission FAQ's
Do I really need a transmission flush?
Sometimes. If your fluid is simply worn, discolored, or low, a fluid service can help extend the life of your transmission. However, if your transmission is already slipping or has internal damage, flushing it can make the issue worse. This is why we always perform a diagnostic evaluation first—we only recommend a flush if it’s beneficial for your vehicle.
How often should I change my transmission fluid?
It depends on your vehicle and driving habits. Many manufacturers recommend a transmission fluid service every 30,000–60,000 miles. If you tow, drive in heavy traffic, or have a work vehicle, servicing your transmission more frequently can prevent expensive repairs down the road.
What are signs my transmission needs service?
Watch for:
- Delayed or hard shifting
- Slipping between gears
- Burning smell
- Red or brown leaks under your vehicle
- High RPM without acceleration
If you notice any of these signs, schedule a courtesy inspection—we’ll evaluate before recommending any repairs.
Is it better to repair or replace a transmission?
Every situation is different. Sometimes a failing sensor or module is the only issue. Other times, a transmission rebuild or replacement is the most reliable and cost-effective solution. We’ll walk you through your options, explain what’s worth the investment, and help you decide what makes the most sense for you and your vehicle.
Do you offer rebuilt and remanufactured transmissions?
Yes, and we do all rebuilds in-house. We can also install remanufactured units when appropriate. Every build is backed by a nationwide ATRA warranty, so you’re covered wherever the road takes you.
Can I drive my car if the transmission is slipping?
We strongly advise against it. Driving with slipping gears can cause severe internal damage and increase repair costs. If your vehicle is unsafe to drive, we offer free towing with approved major repairs (within 25 miles).
How much does a transmission repair cost?
Transmission repair costs can vary widely depending on the type of repair, your vehicle's make and model, and the severity of the damage. As a general range, minor repairs such as a seal replacement or sensor fix may run anywhere from $150 to $500, while more involved repairs can range from $1,000 to $2,000 or more. A full rebuild or replacement typically falls in the $3,000 to $7,000+ range.
That said, the only way to give you an accurate number is to inspect your transmission first. At Gus's Gears, we provide a clear, itemized estimate before any work begins, so you'll always know exactly what you're paying for and why, with no surprises.
How long does a transmission repair take?
It depends on the type and extent of the repair needed. Minor repairs, such as replacing a sensor or solenoid or fixing a leak, can often be completed in a day or two. A more involved repair or full rebuild typically takes anywhere from three to five days, sometimes longer, depending on parts availability and the complexity of the work.
We know being without your vehicle is an inconvenience, so we always aim to give you an accurate timeline upfront and keep you informed throughout the process. Our goal is to get you back on the road as quickly as possible without cutting any corners.
