    According to recent studies, 5 percent of all motor vehicle fatalities are clearly caused by automobile maintenance neglect.

    The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of coolant should be checked. (A 50/50 mix of anti-freeze and water is usually recommended.)

    Never remove the radiator cap until the engine has thoroughly cooled. The tightness and condition of drive belts, clamps and hoses should be checked by a pro.

    Change your oil and oil filter as specified in your manual, or more often (every 3,000 miles) if you make frequent short jaunts, extended trips with lots of luggage or tow a trailer.

    Replace other filters (air, fuel, PCV, etc.) as recommended, or more often in dusty conditions. Get engine drivability problems (hard stops, rough idling, stalling, diminished power, etc.) corrected at a good shop.

    A dirty windshield causes eye fatigue and can pose a safety hazard. Replace worn blades and get plenty of windshield washer solvent.

    Have your tires rotated about every 5,000 miles. Check tire pressures once a month; let the tires cool down first. Don't forget your spare and be sure your jack is in good condition.

    Check your owner's manual to find out what fuel octane rating your car's engine needs then buy it.

    Keep your tires inflated to the proper levels. Under-inflated tires make it harder for your car to move down the road, which means your engine uses more fuel to maintain speed.

    Lighten the load. Heavier vehicles use more fuel, so clean out unnecessary weight in the passenger compartment or trunk before you hit the road.

    Use the A/C sparingly. The air conditioner puts extra load on the engine forcing more fuel to be used.

    Keep your windows closed. Wide-open windows, especially at highway speeds, increase aerodynamic drag and the result is up to a 10% decrease in fuel economy.

    Avoid long idling. If you anticipate being stopped for more than one minute, shut off the car. Contrary to popular belief, restarting the car uses less fuel than letting it idle.

    Stay within posted speed limits. The faster you drive, the more fuel you use. For example, driving at 65 miles per hour (mph) rather than 55 mph, increases fuel consumption by 20 percent.

    Use cruise control. Using cruise control on highway trips can help you maintain a constant speed and, in most cases, reduce your fuel consumption.

    Keep your engine tuned. A fouled spark plug or plugged/restricted fuel injector can reduce fuel efficiency as much as 30 percent.

    Inspect the engine's belts regularly. Look for cracks or missing sections or segments. Worn belts will affect the engine performance.

    Have the fuel filter changed every 10,000 miles to prevent rust, dirt and other impurities from entering the fuel system.

    Change the transmission fluid and filter every 15,000 to 18,000 miles. This will protect the precision-crafted components of the transmission/transaxle.

    Inspect the suspension system regularly. This will extend the life of the vehicle's tires.


    "We brought in our Jeep grand Cherokee, it was starting out in 3rd gear and had a check engine light for a governor pressure solenoid. Chris test drove it and felt it could be fixed with a new pressure solenoid & sensor with a transmission service. Another shop would not even quote us on this option, told us the transmission had internal damage and needed a complete rebuild for $1895. We were not willing to pay that much and were looking into replacing the vehicle. We brought it to Speedy and got the recommended repairs, there was no internal damage to the transmission, the sensor and solenoid fixed the problem and the transmission is working perfectly! I work in the automotive service industry, I appreciate that they did the needed repairs without trying to upsell based on the age and mileage of the vehicle. Everyone was friendly and professional and I highly recommend them! I refer my customers to them for transmission repairs."

    -Mark Brown - Acworth, GA

    "I had a great experience. I found them in a Google search. They did everything they said they would. The price didn't exceed their estimate. They paid for me to get home when I pulled my van up in 2nd gear. They were vey friendly through the entire process, from the staff in the front, all the way to the service tech that stayed over 15 minutes so I could get it back a day earlier than they originally thought. Bottom line is they are honest, competitive, and the best out there in an industry full of crooks. Thank you Speedy Marietta-Transmission Shop for giving me my livelihood back ahead of schedule."

    -Dana B.

    "I have been a vendor for Speedy Marietta-Transmission Shop for over 7 years. Kristina, Josh and their staff are the most genuine, honest, hard working people I have met in this business. They put their client needs before their own. They will analyze your situation and only make the necessary recommendation for your transmission. Over the last several years, I have watched this business grow to be the most reputable transmission repair shop in the area. This is a testament to their faith and their focus on helping others. Call them or better yet stop by, once you meet them you will know that you have chosen the right place for you transmission repair needs."

    -Jeff H.

    "Quality, professional, and dependable service in my time of need. Thanks so much for getting my family back on the road so quickly! Your kindness was so appreciated Kristina and team!! "

    -Tanya Wilson - Garner NC

    "One of the best car mechanics I've ever worked with. My 2004 VW Passat had what I thought was a bad transmission. Speedy Marietta-Transmission Shop figured out that it was actually a computer system problem and instead of spending $4000 on a not needed transmission, I spent $1200 on resetting my computer system and replacing some transmission mounts. Needless to say, they were a life saver. 10/10 would recommend to anyone. Very attentive and great customer service, fair pricing, and fast but great work."

    -Madeline S.

    "Kristina and her team are fabulous! Honest, fair, and fast."


    "What a great experience! I recently took my 04 Trailblazer to Speedy Marietta-Transmission Shop and I can't say thank you enough to Kristina Magic and Chris. It's so hard nowadays to find good, professional and HONEST people. They are extremely knowledgeable and the price is so reasonable (don't get me wrong, it hurt to pay $2k but it would've been a lot more somewhere else) for the quality of work they do. They were in constant communication with me during the repair; they have this text message system that informs you what stage of the repair your car is in - kudos for that. They stayed within the price range they told me before they took the transmission down even though unexpected additional repairs were needed. I love the fact that they invest in training for their team, as a matter of fact Chris was about to go to Vegas for some additional training. All in all, I would definitely recommend Speedy Marietta-Transmission Shop 100%."

    -Alberto V.

    "Best kept secret in Marietta. Not only do they have a system that auto updates you every step of repair, but it comes with a one year warranty. Josh is AWESOME, ask for him. They also have 1 of the 3 master transmission technicians in Georgia. They definitely know their stuff. They even cut me a break on my transmission repair for Christmas. I am soooo glad that Falcon Towing recommended them. Thanks Josh and Kristina!!! "


    "Better customer service you won't find. Quote and work were exactly as stated, done on time and I was kept in the loop on each step via text. I will tell anyone who needs a transmission or transmission work to go see Kristina."

    -Lee G.

    "LOVE THESE PEOPLE! I admit I was scared to go to any transmission shop because I don't know anything about transmissions so whatever I am told I wouldnt know any better. My car was really acting up and I feared the worst but after these folks diagnosed it they called to say I did not need a new transmission. It was just some electrical thing and they fixed it for $89. Don't think I'll be going anywhere else. They even gave me a ride to work when I dropped it off. Ask for Christina!"

    -George L.

    "Finding a reputable transmission repair company isn?t an easy task. You can stop your search and put your TRUST with Kristina and Speedy Marietta-Transmission Shop. They provided me a free diagnostic, provided a detail estimate once they were able to look at my transmission, and TRUE TO THEIR WORD with NO HIDDEN CHARGES. I?m ecstatic that I have found Kristina and Speedy Marietta-Transmission Shop and experienced their ASTONISHING SERVICE and TIMELY REPAIR."

    -Rob M.

    "This transmission shop is the best place to go if your car's transmission needs repair. Their prices are fair, their team is honest, and their work is complete. "

    -Celeste S.

    "The best place to get your transmission taking care of, Kristina is the best at making sure you receive quality customer service. She handles everything from informing me of what was being done, to how long it would take. She even contacted the warranty company, so I didn't have to do anything but pay my deductible. The time she told me my car would be ready was right on schedule. Excellent service!!!!!"

    -Mack J.

    "Kristina is awesome! They replaced the transmission in my mustang after a horrible situation at AAMCO in which I was taken advantage of because of my gender. Kristina coached me on what to say in order to get my car out of AAMCO without having to pay them the ridiculous $750 that they were asking for (for taking my transmission apart without my permission) and it worked. Speedy Marietta-Transmission Shop took my car in after hours from a tow truck while I was at work, found a transmission for me at a discounted price and had my car ready for me in less than a week! Thanks so much! You guys are the best!"

    -Jasmine G.

    "I bought a new car with a 30 day limited warranty. I believed there was some kind of transmission issue. Speedy Marietta-Transmission Shop detected the problem, repaired it, and also took care of all claims that my warranty allowed in a timely, pristine fashion. If you have a transmission issue, I highly recommend them!"

    -Kevin R.

    "This is a very overdue review. I do apologize to Speedy Marietta-Transmission Shop, but most of all to the beautiful people in Georgia and travelers from all places of course. Speedy Trans is not only very professional, knowledgeable,and more than capable of diagnosing and repairing your vehicles. Speedy Marietta-Transmission Shop will work with you to give you the best price possible. In our family's experience we saved literally thousands of dollars. We were told a certain price in the beginning; yet due to some unforeseen complications the price went up drastically. Not only was the price originally more than fair, but after I was told about the price accumulation due to the complications I mentioned before, Kristina (owner/operator of Speedy Marietta-Transmission Shop) informed me that not only would she keep to the original price that she had given me, but that to take care of the difference, she would take up the rest of the financial burden. Kristina also decided to upgrade some things on the motor home's transmission computer for free since they already had it down. Honestly of all that I have mentioned so far I personally don't think you can easily find this combination anywhere! And after all of this review the real reason our family and friends would undoubtedly go to Speedy Marietta-Transmission Shop is due to the unbelievably great people that make up the Speedy Marietta-Transmission Shop family. I know it's a long review ,but I also know how important it is to pick the right shop to trust and put your faith in. As far as I'm concerned, Kristina and her families (her own family and the shop ) were a true GOD send during the week of Christmas and New Year's when a family from Chicago was stranded in Atlanta on their way to Miami. At a time when everyone around us was taking advantage of us due to our situation, GOD sent us to Kristina who not only gave us hope, but was the best Christmas gift ever to this day. Not having the right equipment for a 31' motor home, they went out of their way to help us. My childrens' birthdays were also in the first week of January which Kristina also went out of her way to get them presents. Every year after my mother's diagnosis of cancer I try to take her to Miami as a personal promise for her fight; yet as a result of our great experience with the Speedy Marietta-Transmission Shop family we have added a special stop by the shop as our new tradition, because at least for the Delgado family they have earned such respect. I truly believe that they will also instill their best for you; being that it is in their nature to be more than only a shop. You can't go wrong choosing Speedy Marietta-Transmission Shop. Thank You again Speedy Marietta-Transmission Shop from the Delgado family. "
