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.

Transmission repair What is a transmission flush and why is it necessary

Schedule Transmission Repair or Replacement in Smyrna, 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 Smyrna, 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 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 at McCullough has been taking care of my family's [multiple] cars for over 10 years now. A Volkswagen, a Nissan, and 2 Acuras: They've done minor repairs all the way to major transmission replacements. Eric is trustworthy, honest, and tells you what really needs to be done versus what can wait. Their prices seem reasonable (although in fairness I haven't been anywhere else recently b/c I'm so pleased with them), they are timely, and always communicate what the car needs in detail. I can't recommend these guys enough!

    Had experienced front tire damage hitting metal debris on I-285 just before Rosewll exit. Immediately exited on Roswell and saw NAPA sign and pulled in. Place was busy! But got attention immediately by Jeff service worker. Got tire off my car no waiting. Wow! Determined rim bent but tire still good. He could have sold me a new tire and i would have not known better. So appreciative. Then met with Eric McCullough and quickly arranged to have rim fixed. I decided on new tires for safety and were worn. Eric got me great deal on tires and had my car fixed SAME day. Eric runs a super customer-focused operation. Kudos! Bruce Fike

    I know for me one hard thing about choosing a mechanic is brushing off all previous notions I have about mechanics Potentially not treating my car how they would treat their own car. This place has done more than exceed my expectations. I got a phone call for every update, I got a thorough description of what was to be done and what was wrong, not only that, but where the dealership said it would take them two weeks to fix my car, these guys did it in less than 24 hours. I have never been happier to spend $300 in my life. Anything I need in the future, you can be sure I’ll bring it here.

  • Graham was great and was up front about everything that needed to be done. My son's jeep went down on the Saturday before Memorial Day and they had him ready around 1pm that Thursday. Quick turn around in my eyes. Nice employees, everyone was cordial and friendly.

    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!

    Quick 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!

  • This place is a life saver. Great communication, great service, and very professional people. Eric worked with me through my whole repair. Kept me updated through out the process and fixed the problem on my car at a fair price. I will definitely make this my new place to go for all my car repairs and maintenance needs, along with sending my friends their way.

    This 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!

  • I 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.

    McCullough 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.

  • Able to fix issue with my 2011 truck other shops could not address- very hard to diagnose mechanical issue another reputable shops couldn’t figure out. Good prices, done on time, and with expert mechanics. Will have them work on all of my vehicles and highly recommended. Support a family owned business for a change!

  • I 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.

    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!

    After recently moving to the area, I had a vehicle emergency where my transmission needed replacing. Graham immediately took me in and was SO kind, professional, and direct about the costs; one of their kind staff members even drove me home after my car was dropped for repair so that I did not have to call a car service. They were so patient with me and got my car back to me in one day completely fixed and ready to go! I will never use any other automotive repair shop in the area! ABSOLUTELY recommend without hesitation!

    Always extremely professional. Willing to work with customers. Sadly, car repair is expensive but they have worked with me. Graham has been extremely helpful with issues my daughter was having with her car while we were at another mechanic in the area. We asked on Nextdoor for recommendations and McCullough came up numerous times!

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.
