Had a 700r4 transmission rebuilt and had to take the truck back numerous times for leaking. After…read morethe 3rd attempt in repairs, my truck started overheating which it never did the entire time I drove it there. After picking the truck up the third time, it broke down due to overheating. Had it towed where it sat momentarily and the transmission still leaked. I had to make the decision to accept a loss due to not wanting to take the truck for a 4th time and having additional issues once I received the vehicle. I had to take the truck into another shop to diagnose and fix. BEWARE To the shop owner that replied: Please read the review of its entirety! You had (3) attempts! And you couldn't get it right. So miraculously my truck started overhearing after pick up which cracked the heads and the truck went down for a while. Needless to say, I would never recommend this company after all the issues you have given my son and I. Record keeping: it's not my responsibility to keep up with this but my American Express shows the deduction date August 2nd 2025 of $2622 for the rebuild. I suppose it's easier for you to deny if you don't have record. Only reason I waited this long is because the extent of damage caused by the overheating made me replace the entire engine. As a Veteran to others take this warning and be careful when you do business with this company despite the other reviews. The message from the business owner Christian is a copy and paste response. So professional. Even though I spoke to him and his wife or receptionist when the complications were going on. He even towed it from my house. Funny how Christian forgets!

Well, they bent over backwards to help me aslong I had my vehicle in shop before 8am. I arrived at 7:45 am, Scott was opening up shop. I gave him the key & hoofed off to Corner Coffee. Scott shows up at Corner Coffee at about 12:30 pm to pick me up after repairs were done. He tells me that the transmission pump replacement took much less time than anticipated. So he gives me a generous labor credit. I was floored. AAA Auto Care wanted $7K to replace the transmission when all I needed was a pump replacement - a $2K cost. The honesty, integrity and communication was flawless. As a small business owner, I value these principles - and they nailed it. So don't even think twice before having Mr Transmission do your car repair for transmissions, brake work, fluid changes (oil, transmission, brakes, coolant), etc. If they don't do it, you can expect an honest answer. Can't say enough good things about these guys.

If I could rate this place lower...I WOULD...and by several levels…read more Initially, I had taken our 1994 Toyota 4Runner to them with a very, VERY slight transmission fluid leak and intermittent slippage when in DRIVE. In less than an hour after leaving the vehicle with them for their diagnosis, they called to say that the fluid level was low and the fluid pan gasket needed replacing, as did the fluid filter/screen. So, over the phone, I approved the repair work to be done. The next day, not only was the leak back, but it was 20-30 times worse -- not mere DROPS, as it was when taken in for the assessment/repair. The fluid is POURING onto our garage floor. So, I returned the car, and they replaced the "replaced gasket" with a new gasket, and I took the car home. Yep, you guessed it! A couple of days later, the leak is back and worse, now, than it was after the initial repair. As well, their front desk associate -- Cameron, who is the son of the owner -- gave me grief when I expressed my disappointment in their, would let me talk by talking over me. Then I encouraged him to let me speak, if I was to avoid suing them. He then unleashed a tirade of screams, using that narcissistic challenge of, "Do you know who you're talking to?!!! And then hung up on me. I immediately called back, and the owner had been brought to the phone and tried to explain...EXCUSE their shoddy work. First, he thought I was completely ignorant of car repair, not knowing that I'd grown up on a farm, helping my dad repair and retool LOTS of major machinery components, INCLUDING TRANSMISSIONS, manual mind you. Ultimately, I had to FORCE them to remove some of the fluid, they had refilled the fluid level way, WAY, WAYYYYYY beyond the FULL notch on the fluid check dipstick. Since then, the leak essentially has disappeared; however, here's the remaining issue, which I didn't mention, given the fundamental failure to resolve the leak. Not only did leak issue worsen on order of magnitude, but so did the transmission slippage -- now not just in DRIVE, but also in SECOND gear, failing to "pull" from a dead standstill, but will kick in after starting the car in LOW, then shifting upward and settling in DRIVE. Needless to say, HELL will receive a ton of fur coat shipments before I'd EVER take my care back to these guys. And, now, YOU stand forewarned. I'd been referred to them by SIGNATURE Auto Repair, who's just next door, literally, as THEY don't do transmission work. Ironically, neither does this MR. TRANSMISSION. Be warned...or be incalculably sorry!!!

It's just this lot off of Buford Highway that honestly doesn't look visually appealing from the road. A small lot with a bunch of cars randomly parked- no clear parking spots, the entrance of the building is off to the side. We dropped our car off and didn't receive a call or an estimate the rest of the day. We figured they were just busy given all the cars in the lot. That gave us more reassurance that so many cars were there. However, first thing the next morning we received a call letting us know what to expect in terms of cost, what was wrong, and our options. They were very honest, explained everything thoroughly, AND best of all, did not try to push anything on us. We were given the cost estimate to rebuild our transmission with new parts or get a used transmission. They gave us recommendations and did not push the more expensive option on us. We opted for the used transmission, which we were told would take 1-2 days for the part to arrive. We assumed we wouldn't get the car back until the next week. The very next day we were called and told the car would be ready in 2 days. Much much faster than anticipated. They offered to replace the clutch for us too, which we declined and they didn't try to push it on us. The next day, we were updated on everything, and we decided to go ahead and replace the clutch. Despite this, the car STILL finished before the anticipated time. When I picked up the car, we were informed that he fixed another part for us and refilled the coolant for no charge, the transmission has a 6 month warranty, and lastly, I mentioned a discount on the website for $100 which he happily applied to our bill. The car drives amazingly. The clutch feels great. The transmission works perfectly. Shifting gears has never been easier. We are so pleased with the work, the speed, price, and how thorough the communication was. Trust the reviews and take your car here for any transmission needs.

We had to call every few days to get an update or we would hear nothing. We finally got the car back after about 2 1/2 weeks. It seemed to run fine. After a few months, however, we were still having transmission issues and were provided diagnostic codes when we took it to a near by auto part store. Fine. It's under warranty. We take the car back to the shop. Our vehicle sat at the shop for legitimately 1.5 weeks with little to no calls or updates. We finally retrieved our car without our warranty repairs as we were given excuses about how short staffed they were and how someone had jury duty, blah, blah, blah. Meanwhile, we're renting cars, taking Lyfts, Ubers, etc... all while the car is just sitting there. Simply said, this shop does not honor their warranty or at least not with any urgency at all. If you have 100 years to wait.. then maybe your experience could be different.

They told me that it was just a leaking hose, and according to them, it was fixed, they charged me $78 and told me it was good to go. I returned the same day, since the car was still overheating, and they told me to leave the car at the shop, and more than one month passed, and the car wasn't even touched. I went by Speed Auto Shop and they told me they could not find the new radiator for my car. After a few days they removed the radiator and they call me to take the radiator to Sims Radiator Shop, which I did, and the radiator shop cleaned up the radiator and returned it back to me. I took the radiator back to Speed Auto Repair, and after 3 days they contacted me, telling me that the radiator was back on but still leaking, because of the wrong cap on the radiator. He could not tell me what PSI radiator cap is needed, so I had to drive the car while leaking antifreeze to Sims Radiator Shop in Lawrenceville, the car had no gas, it had a flat tire, the trunk handle was removed and placed inside the trunk, and there was dirty handprints all over the car. When I go to the radiator shop, they placed the 13 PSI cap on, it stops leaking, but after I drove it around, it began leaking again, the car had to stay at the radiator shop for the thermostat to be tested. Speed Auto Repair charged me $812 and my car was never fixed. That guy Jim should not even be working on these cars at all.

I took my car to Gann's Automotive, where the owner, Paul Gann, told me the engine had failed and…read morethat the car was unsafe to drive. He advised that I replace the engine immediately at a cost of over $5,000. He also told me the car was worth less than $2,000 and suggested I buy a new one. As a mom who had just been in a recent car accident, hearing that my car was "dangerous" was extremely stressful. I felt pressured and rushed into purchasing a new vehicle I hadn't planned on buying. Before selling my car, I decided to get a second opinion at CarMax. They found nothing wrong with the engine and ended up buying the car from me for $7,000. Being given incorrect information in that situation caused unnecessary stress and financial impact. I strongly recommend getting a second opinion before accepting major repair advice from this shop. I will not be returning and cannot recommend this business.

We did buy a car from Ganns several years ago and they honored the warranty had to brig it back several times. Unfortunately, the most recent experience the gasket they fixed for the Caravan fell off. I brought it back and they put it back on. Ganns did my last oil change. I am at a different auto center today because check engine light came on and asked them to do oil change. Ganns did it way to tight, and also big oil leak end result needed new pan and what was going to be a $150 is now $500. I shared with Brian the head mechanic what happened and he said we fix oil pans all the time. The manager where I am at said that is all he had to hear if they fix oil pans all the time the mechanic is not doing them right. This was clearly Ganns fault and I didn't bring it back to them because I need the car today and usually 2-3 days for Ganns to repair your car if your lucky. The one other experience I will share is that one time Paul could not figure out why the car would not start. I didn't mind paying a normal diagnostic fee but he was charging like $140 and no repairs were done which I thought was excessive. I did complain and he more or less asked me to leave didn't pay anything and that was not my intention . The bottom like I am done going to Ganns if I need to drive to Lilburn so be it.
