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.

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

Schedule Transmission Repair or Replacement in Roswell, 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 Roswell, 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 Roswell 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!

    We have been depending on McCullough's at least since 1997, when we purchased a home only a few blocks away, walking distance really. Had our emissions test a few days ago and want to acknowledge Jack, who completed the tests quickly. I asked him to determine why the backup camera was not in the proper position. It took a bit of time and ingenuity to get everything right. Thanks Jack, for the excellent service.

    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!

    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++++++

  • 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 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.

  • Eric 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

    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.

    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.

    I 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.

  • 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.

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!!!

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 Roswell 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.
