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! Thanks again to everyone at World Class Transmission in Mendon, Massachusetts!!! This place is truly world class!

They had it done in a day, and now, a few months later, it's still running... I think it's shifting a tad firmer than it did originally but I may ask about switching the tranny fluid to AMSOIL transmission fluid, a number of people I know using it, swear by it! Overall, I'd use them again if needed and recommend them...

In short... These guys are phenomenal, if you want a good repair on your transmission done by…read moreknowledgable staff, just go to theses guys. I took my 2003 Lincoln Aviator to them after looking into multiple repair options. I am so glad I did because after they took a look at it I was told I only needed a small part, quick, easy and lasting repair. (I had it towed to them to avoid any further damage and would recommend you too as well). When I took the car to them I thought I was looking at $3,000 and it ended up at $500. By the way it took less then 24 hours for them to have it done. In summary if you want your repair done right, quickly, and by the right people... go to New Tech Transmission.

Their March 1 repair record shows they replaced the rear subframe, suspension, and brakes. By September 1, the car broke down and a second shop found loose parts, an incorrectly assembled rear end, and front differential failure -- the same areas that had just been repaired. This happened within about 10,000 miles, indicating repair issues, not driver misuse. By October 1, the transmission also failed, leaving me with no vehicle.

They were recommended to me by my regular car service guy when my car needed transmission work.

They checked the transmission out, replaced the seals and filter, installed and tested it. I had to drive 30 miles to get to their shop and if I had to drive 100 I would do that. Can't say enough nice things about them.

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!

Hmmm must be some personal nonsense being taken out from behind a screen...but anyways onto the more pressing matter... Tim and his son Junior are probably by the far the most stand up guys around. Its true there are honest mechanics around who actually know what the hell they're doing and stand behind it! I know believe it... They have done some beyond amazing work on my 06 Rubicon. If your looking for lift for your 4x4 toys look no further. And thats just a taste of what these guys can do for your vehicle. Their shop is equipped with the best equipment there is to get the job done right. Their work is flawless and Ive had the pleasure to watch these guys in action, and their attention to detail seems as though they are cranking wrenches on their own rides which was very comforting. Anytime an issue pops up or I have a question about anything tim is my go to guy. His many years of experience shows with his helpful knowledge which he graciously and honestly shares without a chip on his shoulder. All in all if your near or far, this is the garage you pull into and hand your keys over with the utmost piece of mind. Ill be a lifetime customer without a doubt. Thanks Tim and Junior! You guys are truely a rare breed. Keep it going!
