Schedule Cadillac Transmission Repair in Atlanta, Georgia
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. Your Cadillac’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 Cadillac.
McCullough NAPA Auto Care staffs ASE Certified technicians with the experience and technology to properly diagnose any transmission issues you may be experiencing with your Cadillac. We’ve been in business since 1969 and have ample experience repairing and replacing transmissions for any Cadillac model, including the Escalade, XT4, XT5, XT6, CT5, CT4, and more.

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!

November 19, 2019My experience here was great! Fast, curious, and fairly priced. I didn't think a repair shop like this existed. I'll be a lifelong customer.

August 6, 2020Always 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!

I have an older vehicle so I see these folks more than my wallet likes. They are amazing, friendly, people that are a pleasure to work with. I can't recommend them enough.

November 4, 2020I received great service from this location! I called them about replacing a serpentine belt and they got it done for me the very next morning. It was quick, and cheaper than some other places that I had called for the same service. Eric and his team did a great job, and they were very nice! I will definitely return for any other auto repair I may need in the future.

They diagnosed and repaired my car in time for my trip. Car works great! Eric provides excellent customer service even when he's got a ton on his plate.

May 10, 2022Eric 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 have used this company twice and was VERY impressed both times with the honesty, knowledge, and cost-effectiveness of the mechanics that I worked with. They were upfront with me on what I needed to do now vs what could wait, showed me where I could save money, and worked with me to make sure I had my car finished before I needed it that weekend. Again, very very impressed. I wouldn't take my car anywhere else in Atlanta.

What more is there to say? These guys are amazing. Their service is very thorough and quick. I was so worried about the cost of my repair but Eric and Brian put me at ease with their extremely reasonable prices! My truck is running like it's brand new again and I can't thank these guys enough!

March 1, 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!

October 9, 2019I may have written one other recommendation in my of 50 years, but after doing business with Eric McCullough for 35 of those years it is time to write another one. He maintained and serviced my auto's, my wife, kids and employees for 32 of those 35 years. He has stood behind the work on everything he and his employees have done. He operates his business with great honesty and integrity. I highly recommend doing business. with McCullough

I had a check engine light on Saturday afternoon, ended up being an engine coil pack needing to be replaced. It was obviously super busy and I knew I would need to leave it until Monday to get looked at. Staff was very informative and communication was excellent. Got it looked at Monday and ordered necessary part to come in the next day. Went ahead and did the spark plugs as well since I was nearing 60k miles. Picked it up after lunch with no issues. Seems like they do really well with the small space provided and very busy area right off 285

July 21, 2021Had 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

August 1, 2020I 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!

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, 2020WOW!! An amazing experience! Traveled here from Kansas to apartment shop for my daughter who is relocating and my husband was unable to join A part was dragging under the car so we popped in to see if they could help. They were so kind and helpful. Restored my faith in this world. Good people do exist!!
Angela Drybread
June 18, 2022After 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!

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!
Andrew r
June 10, 2021This shop is the best. They did everything they could so I would have minimal time without my car such as having all parts ready before they scheduled the repair. They are super nice and no surprises on price. They opened up my bumper and found a part was damaged. They could have left it the way it and no one would have known but they were honest and did the right thing. I recommend 100%.

Honest experts . affordable compared to other places . Only place that was willing to work on my subaru head gasket and other axle work from maybe 5 places I went to .
Ketan Gunjal
January 7, 2021A staff of gentlemen ready to answer every question with a smile and great knowledge. They not only gave me a good estimate but they completed the work a day early! I highly recommend McCullough NAPA Auto Care to you. You will not be disappointed by the care they put into your vehicle.

My parents and I have been taking our cars there since the beginning. Great, hardworking guys. The only mom and pop shop left in Sandy Springs.
kirby caramelo
January 2, 2022I was so impressed with these guys!! Family business and the guys are professional, efficient, and personable. They got my part quickly and fit me in so I could come while my kids were at school. They went the extra mile (no pun intended) to consult with another auto body shop to make sure the repair was stable. I will be coming back for all future auto needs and will recommend them widely.

We had an issue with a splash shield dragging and overheating. We are heading back to Kansas this afternoon. They were able to fit us in despite being super busy & do a quick fix and sent us on our way in 10 minutes. So kind and amazing service!
Emma Perez
June 18, 2022I have used McCullough for maintenance on my prior vehicle and received great service. Recently I had to repair my front bumper - I received an estimate for repair services that was reasonable. The estimated turn around time was less days than other auto shops. The best part was, the staff (Graham) was accommodating with my schedule and the repair was completed as expected/on time. The work completed was great. I absolutely recommended McCullough for auto care services.
Jessica Astrid George
February 23, 2021My 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.

Signs Your Cadillac Needs Transmission 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 Cadillac 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 Cadillac 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 Cadillac 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.
