I took my keys back and left that shop. Mark at the Transmission Factory was the polar opposite in terms of his customer approach and professionalism. After a 3 minute drive in my car Mark said I did not have a transmission issue but did likely have a bad driver side front wheel bearing. He subsequently gave me the names of two repair shops he knew to be capable and fair. I did not spend one penny at Marki's shop but here I am writing him a glowing review. I plan to use his shop and recommend him to friends and family. I very seldom write reviews but in this case, II'd give him 10 stars if I could. Integrity and professionalism matter.

I took my car to Cupelli's hoping for a fair and skilled diagnostic. Instead, I was quoted $250…read morejust to scan the car for a "stage 1" diagnostic, with another $150 if it went to "stage 2." They also made it clear that this charge wouldn't be applied toward the repair, which already didn't sit right with me. They did a quick visual check for a leak and my misfire, then told me I'd have to pay for two hours of mechanic labor to diagnose further. This felt excessive and not in line with how most reputable shops operate. The very next day, I went to another high-end European/exotic car shop. They scanned my car for free, visually identified the leak immediately, diagnosed the engine issue, and fixed everything the next day. My car now runs like brand new -- all without the inflated "staged diagnostic" charges. Cupelli's might be fine if you want to overpay just to be told what's wrong, but in my experience, there are much better Euro shops in the area who are honest, transparent, and far more efficient.

This shops carelessness and poor attention to detail cost me even more after leaving their shop.

Sand paper was left all throughout the car and some parts of the car had scuffs like they were about to paint, but changed their minds. This is a forewarning to anyone that's thinking about going to this shop. DO NOT GO HERE!!

Atlantic Transmission is the WORST mechanic I ever used in my entire life. The transmission on my…read moreMercedes Benz died after 168,000 miles, so I called Atlantic Transmission, and Becky answered. She told me to bring the car in for a "free estimate." I took it in and asked Mark, the owner, to assess the transmission and give me his honest opinion on whether the car was worth fixing. I explained that I was debating whether to fix the transmission or buy a new car. I then asked him for a ballpark estimate of the cost to fix my transmission, both the best-case and worst-case scenarios. Mark's initial quote was "between $1,800 and $3,500." I left the car with them, and a few days later, I got a call from Mark saying I needed a rebuilt transmission, and it would cost $4,500, plus fluids. I asked him again if it was worth fixing, and he assured me it was the right decision. Trusting Mark's advice, I gave the go-ahead to fix it.(HUGE MISTAKE TRUSTING MARK). Several weeks later, Becky called to inform me that the rebuilt transmission had been installed, but the car now needed a "conductor plate," which she explained is the computer that tells the transmission when to shift. She said but first, Mark required payment of the initial $4,700 (including $200 for Fluids) because the rebuild was done. However if I wanted the car to actually shift, I would need to buy this "plate." I asked if the car worked, and she said, "No." She reiterated that I needed to come in and pay because they had installed the rebuilt transmission. When I went to pay, I found out they don't accept credit cards--only cash or debit, which I later realized was intentional so you can't dispute the charge. We discussed the new "plate" further, and Becky mentioned it was very expensive, around $3,500 from Mercedes, but she could get one from China for $1,000, though it would take three weeks to arrive. By this point, I had already been without a car for a month and was now being told it would take another month plus $1,000 to complete the process. Having already invested $4,700, I decided to spend the extra $1,000 in hopes of getting a working car, even if just for another year. I signed an estimate for the $1,000 to approve the "plate." A few days later, Mark called, saying, "Becky doesn't know what she's talking about." He explained the plate alone was $1,000, but with labor, it would actually cost around $1,800, peppering the conversation with F-Bombs. He said he'd call when the car was ready. The next call came sooner than expected, and Mark told me the transmission was fixed and shifting properly, but the engine was now misfiring, showing numerous codes, and they couldn't clear them or get the engine to run properly. I told him there were no engine codes before the transmission failed. Mark then raised his voice, shouting that he fixed the transmission and that he's a transmission repairman, not an engine mechanic. He claimed the car had all those misfire codes when it came in. I asked him why, if he knew about the engine misfires when I first inquired if the transmission was worth fixing, he didn't mention them? I would never have spent money fixing a car with a blown transmission and multiple engine codes. Mark suggested the misfires would be an "easy fix," but the bill for the plate was now $2,700! At this point, I was beyond furious. I went to the shop in person, and I negotiated the plate payment down to $2,100 in cash, bringing the total cost for the transmission repair to $6,800. I left the shop with a poorly running car and immediately took it to a local mechanic to address the engine misfires. That mechanic had the car for two weeks but couldn't clear the codes or identify the source of the misfires. I paid $360 for diagnostic time and took it to a second mechanic, who told me the car WAS NOT worth fixing even with the new transmission. I ended up trading in the car and got just $1,000 for it. Mark is unethical, dishonest and delivered the worst car mechanic experience in 40 years of owning cars! RUN AWAY FROM ATLANTIC TRANSMISSION, MARK & BECKY!
