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 Smyrna, Georgia. Contact us to schedule your appointment and to receive your complimentary multi-point inspection with scheduled service.

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 Smyrna 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.

Eric was amazingly helpful to work with. Great communication around the whole process. He was great about calling out things that could be done without being pushy about doing them. Would highly recommend!

This place is right by my house. I was really happy with the customer service. I was worried about affordability and turn over but they were efficient and I will be back for any future needs.

August 30, 2020Eric 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.

January 23, 2020This has to be the best shop in town! When I got my car fixed the last time, It drove live new. I've never been so happy to get my car fixed in my life. They were very friendly and honest. This will be my go to place from now on. Not too far from my house which is a huge plus but even if it were, I'd be game to making the trip. Thanks for being honest and giving great service!

My vehicle was on the verge of breaking down while I was in Sandy Springs for work last week (I live in a different town), and my boyfriend had determined that it was a problem with the alternator. He helped me find McCulloch Auto Care, which was right down the street. We'd noticed the good reviews, and we took a chance! The staff is super friendly, professional, and kind. They were able to confirm our suspicions about my car's specific issues, and took us as soon as they could. I was so impressed with their customer service. They really went above and beyond to meet my repair needs, had a fair price, and worked quickly to repair the issue. I almost wish I lived closer just so that I could have my car serviced here more often! Great family owned business.

February 15, 2021Quick and excellent service. I was turned away at my regular mechanic because he said he didn’t know how to do a transmission fluid change. This was my first time ever going to McCullough auto care, and I was very happy with my service. They were able to see me immediately and were patient with me considering the circumstances. Eric was great, and even matched the prices of another mechanic down the road. I will be back! Would recommend!

August 2, 2021McCullough has been my family's go-to mechanic for decades. Don't know what I would do without them - just a super-nice family that will take care of your cars. Their service is important to us because once we get a new car, we like to hold onto it for years (10-12). Highly recommend.

July 1, 2020Great 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!

Brian and the team were fantastic with handling my issue. In fact they discovered a major error which occurred when I had my last oil change done at a quick oil change place, which turned out to be the cause of my issue. They took pics of it and wrote out an explanation for me to give to the previous oil chance place. Because of their extra effort, I am getting reimbursed for the error. I highly recommend Brian and the team!

February 3, 2022Eric was amazing from start to finish. I chose this shop for my repair based on previous reviews & I'm glad I did. He made sure to, in my opinion, go above and beyond with his politeness, as well as helping to make the process smooth and to try to save me as many coins as he could, while still getting done what was needed. Very happy with this visit

Out of town for work and needed an alternator changed immediately and McCullough's was the only place that said they could and would do it! Reasonably Priced and Great Customer Service! Will definitely be back if ever in the area.

January 19, 2022I live in Brookhaven and work in Duluth and pass dozens of auto repair shops on the route. I will forever go out of my way to go to McCullough. This is hands down the best repair shop I’ve ever been to. They are honest, kind, and treat each customer with the utmost respect. I’ll never take my cars anywhere else!

I have known Eric and the facility for over 30 years. The service from both a customer and repair stand point is excellent. You can expect to be treated with a high level of professional performance, and courtesy.
Mark Schacher
January 23, 2020I would normally recommend this business as I have been here a few times. I went there Friday for an oil change. However, I honestly didn't feel safe. They have signs that customers must wear a mask. There was only one employee wearing a mask themselves. All the others didn't have a mask on. I feel this is disrespectful to their customers. I understand it can be uncomfortable but it is essential during these times.

I do not know if I can type out all that I want to in this review but let me say this. WOW!! Being a single father with a busy schedule I cannot tell you enough how grateful I am for Eric and his team! I have been taking my vehicle to them for over 2 years now and I would not go anywhere else. The honesty, timing and keeping their word every single time is simply priceless! They have saved me so much grief because of my current situation. For all you single fathers out there...these guys got your back! I only have one vehicle and my son and I depend on it being in the best running shape possible. Eric and his team go out of there way EVERY-SINGLE-TIME. During these special times where its harder to get even the simplest things done, that has not slowed down this business. They still give 110% with every customer and are sympathetic to their customers unique situations. People, don't look any further for a shop that you can trust and count on. You will simply waste your time and find no better service in Atlanta. Eric, I want to thank you from the bottom of my heart for everything you and your guys do. Having open and honest communication with you is always a pleasure. Folks lets do our best to keep these guys busy!! They deserve everyone's business! A++++++

April 29, 2020I own and automotive repair business in Jacksonville, but my wife lives in Atlanta and needed tires for her car, so I know good service and fair pricing in this industry. I chose McCullough because of their good reviews and they did not disappoint. They were very professional and took good care of my wife. I would highly recommend them and will continue to use them for her service needs.

Most especially, Eric and Wes, they are top notch and I am highly satisfied with the outstanding work on my car. I highly recommend this car repair shop to my family, friends and all over Atlanta. I am extremely happy and highly satisfied with my car repair as well as the car repair cost. Thank you for the outstanding work and the job well done.

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 Smyrna 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.
