"Cannot say enough nice things about the care and service we received. We were on a long road trip vacation when we experienced transmission issues. My husband was at the shop promptly for when they opened. They took him first thing and resolved the issue in no time!! They treated us with amazing kindness and saved the family vacation! This is a shop you want to give your business."
"AAMCO of Portsmouth has the best honest, reliable, customer service friendly mechanics and manager I've ever seen! This was the second time I had used them. They replaced a transmission for me in 2007. They gave me an estimate this year (2017) on my 2008 Mercedes-Benz C300 regarding the transfer case/transmission. Now mind you...I received a estimate at the Mercedes dealer which was outrageous prior to contact Paul. So...instead of paying close to $7100...I only spend $375! All it needed was some ball-bearings in the right front to quiet the noise. I would recommend AAMCO to any and everybody! Thanks Paul and thank your crew for us."
"Paul is a great guy to work with, very honest and fair. Highly recommended!"
"They Handled my transmission issue after I had to argue with the mechanic about what was wrong. At first they told me it looked Grimm and the whole transmission might have to be replaced. I told him it was a common issue with BMW he disagreed. I had to print out a diagram of what was wrong and point it out to him, he still wouldn't admit that's what it could be. After stating they will look at everything and let me know the next day, they called me back and said they fixed it, I asked what was wrong, wouldn't you know it, exactly what I had said. Turned a 7,000 repair into a 200. They still never admitted they were wrong. "
"Paul and his techs helped me out very well, truck was in the shop for a week he called my warranty company to submit a claim and they sent out a adjuster and my warranty fixed my truck and I had to pay minimal amount out of pocket, Paul did the best he could to get me back on the road running with very good work. I will surely send family and friends to him if there are any other transmission problems near future and I as well will be returning if something happens again."
"If you ever have transmission problems GO TO AAMCO in Portsmouth NH!!!!! They are THE BEST! I had some transmission issues on my Cadillac Escalade and Paul..."
