Mike, Marissa and their staff have proven their professionalism and competancy to us time and time again. Knowing that the job will be done right the first time is invaluable and gives us peace of mind when were on one of our trips far from home. We're Certified Transmissions customers for life!" Ken & Christy Foote

At Watters Design & Garden Center we have been running crews around Yavapai county since 1962. We have a lot of vehicles including that cute little VW Beetle dressed up to look like a lady bug. Mike and the staff at Certified Transmission take care of our repairs. A knowledgeable staff that is honest and looking out for the best interest of the customer is what sets you apart in the garden center business, and that's what I like about Certified. They're locals that know what they're talking about and I have found them to be nothing but highly professional. Thanks to Mike and the entire staff at Certified Transmission for all our transmission service, maintenance and clutch service

Sue Felan / Fleet Manager / Prescott College: Certified Transmissions has performed the colleges transmission repairs for the last 8 years. Today's vehicles are extremely complex and, consequently, require knowledgeable, conscientious technicians performing these repairs. As a fleet manager concerned with safety, service and the best quality repair I can only say this: Certified Transmissions is the best in the business.

I have had work done by Mike and his staff on several occasions. This work has included trouble shooting, servicing,and complete rebuilds. The work has always been completed in a very professional manner. I would recommend Certified Transmissions

...I wanted to let you know how very pleased I am with the recent (last June?) work your guys did on my 1991 Ford F-250 diesel with the E40D automatic. I felt that my turbocharged diesel could somehow put more power to the rear tires with some "massaging" of the tranny. Your advice really has paid off! I'm sure you've forgotten by now, but here is what we did and the results I've noticed. We changed the factory chip to a reprogrammed setting. We put a dual disc in the torque converter and we put in an updated valve body with modified shift points. We also added fully synthetic transmission fluid and retrofitted a fluid check stick for convenience. The results have been dramatic. A few days after the work was finished my wife, Terri, drove the truck to Indiana...we really didn't tow anything until December, when we took our 9,000 lb. fifth wheel to Lake Pleasant for a week and then down to Rocky Point, Mexico... The improvements really showed up as I hauled our home around town and then onto the freeways - the shifts off the line were timely and crisp, no more over-revving of the RPMs between gears, no more short shifts causing the engine to start lugging. At no time did the transmission temperature climb over the normal range. Short of buying newer technology, I'm conviced that, with your help, we've made this old truck as strong and powerful as is possible - within my budget. Oh, one more thing. No one mentioned it, but I'm convinced that one of your guys took it upon himself to pound out my bend skid plate under the tranny. It's been bent since I bought the truck in 1997. One more example of the great service and thoughtful help available at Certified Transmissions. So - thank you and your crew for another example of fine, professional work. One Happy Customer, Mark Kuykendall

"I came to Certified Transmissions after having a very trying time at another transmission shop. They were not only very understanding and helpful, but took time to explain everything to me. Their expertise and sincere kindness was very welcoming and restored my faith in mechanics. I would highly recommend their services to anyone in need of superior and honest mechnical help."

"I want to compliment you on the fine service you performed on my truck transmission. The truck runs well and the transmission works beautifully! At all times your staff was understanding, knowledgeable and explained everything thoroughly. When the work was completed, the cost fell within your estimate. I will recommend others to your business for any transmission repair."

"Thank you, thank you! In these times it is often hard to find honest, and thoughtful service. Too many companies seem to feel that once a client is through the door they can be forgotten, and their needs ignored. Your company, Certified Transmissions, is one that made sure our concerns were their problems too. Our very sincere Congratulations on a fine staff. They went out of their way to assist us. Your office manager was courteous and thoughtful. One of your mechanics took our car out for a test drive. After just a few minutes he'd found what was wrong - some computer glitch that had problems making up its mind about which gear was necessary for smooth riding. When the part needed for our car was not on your shelves, and it seemed as though Ford Co. delivery would be hours away on a hot day, your office manager sent one of the staff over to get the part. Few companies now would bother to do that. Few office managers would care about the time a client was kept waiting. As soon as the part was obtained, [the technician] stopped what he was doing on another auto and installed it. It has worked perfectly since then. Another company couldn't find the problem but hmmm thought that maybe our car needed a new transmission. Since that day we've told many folks about the outstanding staff of Certified Transmissions. Thank you."

"Mike, Paul and Crew: after three years of too much money and stress coming from uncaring employees at two different Ford Dealers, you turned the tide for me and my truck. Because of your determination and forth right, you accomplished what others did not. Now everytime I shift the gears, I get a big smile on my face. If I was capable of kicking my heels up in the air, I would. So congratulations on a job well done. Thank you, thank you!"

"Just a note to let you know we made it home safely! Our truck ran perfectly, we took it for the 15 day inspection and all was well. Thanks again to ALL of you for your kindness, professional manner and mechanical abilities. We still cannot believe you got us on the road so quickly! You were all a blessing to us during this stressful time."
