Transmissions are heavy-duty pieces of equipment that are designed to last a long time. But like any other machine, they’ll eventually wear out and need repair. Automatic and manual transmission repair and fluid flushes are common services, but scheduled auto maintenance can prevent major repair and transmission replacement.
McCullough NAPA Auto Care has ASE-Certified technicians with years of transmission repair and replacement experience near East Cobb, Georgia. Contact us to schedule your appointment and to receive your complimentary multi-point inspection with scheduled service.

Schedule Transmission Repair or Replacement in East Cobb, GA
A car’s transmission is responsible for ensuring that the right amount of power goes to each of its wheels at any given speed. Your transmission must work properly, or it may negatively impact other components of your car. Please complete the form below if you have any questions about transmission repair or replacement or if you’d like to schedule a time to bring in your car. We are only a short drive from East Cobb, Georgia.
Signs That Your Transmission Needs Repair or Replacement
Transmission repair or replacement is not a service that you want to put off. A faulty transmission can cause other parts to wear out faster, so we urge you to bring your car in for an inspection if you notice any of these signs your transmission is failing.
1 – Fluid Leak
Transmission fluid is red and smells sweet. Look under your car after it’s been parked for some time to see if you have a transmission fluid leak.
2 – Burning Smell
Old, worn-down transmissions will emit burning smells as they age. This could also be due to your transmission needing a fluid flush. Either way, burning smells are never good, so bring your car in ASAP if you smell burning.
3 – Slipping Gears
It’s unsafe to drive a car with slipping gears as you may not have complete control. You should never drive a car that has gears that slip. If this is the case, schedule service with us soon.
4 – Gears Refuse to Switch
Likewise, if your gears refuse to switch, that’s another problem. This is a tell-tale sign of a bad transmission, but a fluid flush typically will solve the issue.
McCullough NAPA Auto Care has been in business since 1968. During that time, we’ve served East Cobb area drivers with quality auto and transmission repair service that we are proud of. Please don’t hesitate to contact us with any questions about transmission repair or replacement for your vehicle.

May 16, 2022Have been going to McCollough’s for decades! Once I found them, I knew they were honest and professional. Not often one can say that about an auto repair place. They have helped me keep my older vehicles safely on the road for longer than I could imagine. I have always been treated with respect, no matter how large or small the issue, which is excellent and reassuring for an older woman.Highly recommend them!

Very respectful, honest, and professional. I was having issues with my headlights, and they fixed it for a reasonable price. They do a lot to ensure that you have a positive experience, and that you're not wasting your money on unnecessary parts or repairs. Top notch service, A+!

Great customer service! Eric and team did an awesome job coordinating their busy schedule with the schedule of my girlfriend and myself so that we would have a car during the work week and then trade off cars when the other was ready. They are extremely friendly and it felt like they had us as the customer in mind. Highly recommend!

June 10, 2021Eric has been my service manager for years. He is always professional and easy to deal with. He goes out of his way to take care of your needs and makes accommodations to the customer when needed. They will ferry me and my car to and from their shop (I live within blocks) and I appreciate that very much. Everyone at McCullough is nice, friendly and helpful.

May 2, 2021I really cannot count the number of times these brothers have taken care of me, my family and all our various vehicles. We have been loyal customers for more than 20 years! They have done everything we have needed on cars, trailers, used car evaluations for purchase, tank drops, and all the basics. They are very trustworthy and will give you a honest answer on everything and a reasonable estimate on what it will cost to resolve it. They are super busy, so plan to wait a day or two longer than you might somewhere else, but it is worth it!

January 20, 2022Wow! I am so impressed with the service I received. Having moved here from Nashville I was nervous about finding a mechanic! These guys are BUSY but they treat every customer like their priority. I got my car repaired within two days on a weekend! Prices can’t be beat and I was getting phone calls with detailed status updates. Amazing service. Really compassionate. Please doing business! I thought I was going to have to spend thousands fixing the plate that was dragging under my car but I got it fixed for under $200! Thank you!!!

August 6, 2020My truck broke down when we got to Atlanta on the way to Disney world. A local stopped to help us and recommended this place. This place got me in and got the radiator fixed for a very fair price and on our way the next day very quickly. I was so impressed and it's no surprise they are very busy. Thank you so much and my family all got to the resort and is having a great time!! These people are great and will get your vehicle fixed for a fair price. Plus, you get Napa warranty all over the country at least I did on the repair I got. Please support them!!!

How To Prolong The Life Of Your Transmission
The first thing you can do is to make sure your transmission always has enough fluid. Transmission fluid cools and lubricates your transmission’s internal parts. When there’s insufficient fluid, the transmission will run hotter and wear out sooner. The transmission fluid also provides the pressure needed to transfer power from the engine to the transmission. If there’s not enough fluid, your transmission won’t shift properly.
McCullough NAPA Auto Care will check your transmission fluid level as part of our complimentary multi-point inspection with any scheduled service. Likewise, if you see any reddish-colored transmission fluid on your East Cobb driveway, have us inspect it for a leak! A gasket, hose, or seal could be leaking and may need to be repaired.
The next thing you can do to prolong the life of your transmission is to replace your transmission fluid on schedule. As you can imagine, all those gears grinding on each other result in lots of little bits of metal in the fluid. The more there is, the faster the transmission parts will wear out. Transmission fluid also contains detergents and other additives to protect your transmission. These additives are depleted over time, so old fluid doesn’t protect as well as new fluid. Your owner’s manual or service advisor will recommend when you should have a transmission service.
If your transmission isn’t shifting as smoothly as it should, or if you suspect a transmission leak, let us look at it. It may be time to consider scheduled transmission service. Regular maintenance and taking care of small leaks will help your transmission last as long as possible.
