Every step of the process was laid out in detail and The job was even done 5 days earlier than quoted! The shop was even nice enough to make some extra repairs for no charge as a military discount! The inside of the shop was sparkling sparkling and clean and the wonderful auto mechanics were friendly and always kept me up to date with the status of my vehicle! The invoicing was absolutely flawless and I was charged exactly what was quoted. In fact, I paid less than quoted, considering the extra repairs done as a military discount! The warranty is very considerate and generous, right along the lines with what the dealership itself offered. Furthermore, I paid about $2,000 less than I was quoted by the Chevrolet dealership in Putnam, Connecticut. Upon getting into my vehicle I was blown away of the performance! My Chevy Impala drives like brand new with 155,000 mi on it and a brand new transmission and I am confident I could probably drive it another 155,000 miles or more!

Within the first year of rebuilt transmission, a loud knocking noise started so brought it back to them under the "warranty." They stated it wasn't the transmission so I brought it to my mechanic who couldn't figure it out. Brought it to the GM dealership, paid $200 for a diagnostic, transmission and traction control light issue related to transmission. Brought vehicle back to interstate, said they would fix it and take care of related issue. Loud knocking noise were loose bolts inside transmission covered under warranty... Paid them $180 to fix TCM wiring. Week later car drives worse than ever, traction control light comes on and starts bucking. Brought back to interstate, they said it's not our issue, keys are in it. Give your $4k to another reputable transmission place, this ain't it. I want my money back.

They couldn't figure out exactly what caused it to fail, Only that it failed exactly like last time. Second rebuild is on its way out ,around 30k miles in this rebuild car is slipping starting the act like it did before. Brought it back to interstate 2 or 3 weeks ago, with concerns of slipping and metal in fluid . They said pressure readings are in range and no metal found on "dipstick" car drives fine .I personally dropped the trans pan to change the filter and found excessive metal on the trans pan magnet and a loose bolt sitting in the pain. I requested money back. Interstate said no not after 3 years. The counter offer was they could look at it and fix it assuming they found a problem. I declined the counter offer because if the interstate can't fix it the first 2 times then what's a 3rd gonna do

5 Stars - Trustworthy, Professional, and Woman-Friendly Auto Shop!…read more I found D&G Auto Repair thanks to the great Yelp reviews, especially from other women. My longtime mechanic had retired, and I wasn't sure where to go next until I discovered D&G Auto Repair on Yelp! In August 2025, I brought my car in for brake service (pads and rotors replacement). From the very beginning, I felt I was in good hands. Paulo, the manager, responded to my Yelp inquiry almost immediately. He was professional, kind, and attentive. He listened carefully to my concerns and explained everything in a clear, respectful way, something I truly appreciate. I felt a strong sense of trust that he genuinely cared about my car and my safety. When I arrived at the shop, Paulo was just as professional and kind in person. He made me feel confident in my choice to use to D&G Auto Repair. After I left my car, he followed up via text with an estimated bill before starting any work, which gave me peace of mind and control over the process. The shop itself is small but clearly run by expert technicians, and the waiting room is clean and comfortable, a nice bonus! I returned yesterday with a question about a noise I'd heard. Tony, one of the technicians, came out and personally walked around my car with me. He pointed out how clean it looked and even asked about repairs I had done elsewhere. He gave me a mini lesson on body repair which was surprisingly enlightening. He then gave me directions to the nearest Auto Parts store and Car Wash. That kind of extra care is rare and so appreciated. Overall, I highly recommend D&G Auto Repair, especially for women who are looking for a respectful, honest, and trustworthy place to bring their vehicles. I'll definitely be back!

As a woman with limited knowledge, I wanted to be sure not to overpay, so I called a few places and East Coast Auto Repair offered to check my car out the next morning, which worked great for me. (I was right about the high quote from the dealership by almost $400.) I asked the person who greeted me at the shop if they had time to complete a thorough check of the car while they had it for my brakes and they did. When completed, their review included the work on the brakes and only the usual maintenance type things with no pressure for any additional, or possible unnecessary work. In fact, they appreciated my need to control my expenses and made suggestions on how I could get the most out of my car. The people working there were polite, knowledgeable and honest. They deserve their high ratings and I am happy to be able to have found this exceptional auto repair shop close to my new home. I highly recommend them.
