“These guys are the best. They know their stuff, thorough, professional and personable. Update 08/2023 - continuing with new brakes and alot more maintenance etc. Now in our 5th year of great service, regular maintenance and repairs. I totally trust these guys. Always a great experience. I'm a widow now so it's good to have a business you can trust. My son who is a mechanic in St Louis has checked out their work and gives them his seal of approval!!”
“Helped with diagnosis of a suspected problem. Provided me with reasonable options to fix problem if it becomes worse. Complementary inspection performed with guidance to get my car back to tip top shape.”
“Just had the trans rebuilt in my 2017 silverado 4x4 (6L80). Wow.. Paul did a great job, fast and affordable. Best prices/warranty I could find. He put in a shift kit, billet converter, and raybestos clutches. It shifts better than it ever has… very happy with the transaction.”
“Lifetime Transmissions should be named Life Saving Transmissions!! They tackled a problem that no one else in the Tulsa area would touch. Dealers and repair shops all said " replace the transmission" for several thousand dollars. These wonderful people said " bring it in and we'll try to fix it". Valerie and all the staff I met were warm, helpful and completely honest about cost and services. I will use them forever for any future transmission problems. I even recommended them to my trusted auto mechanic for his farmed-out work.”
“I took my Malibu here after taking it to the original place of purchase and was quoted 6500$ and said I needed a brand new transmission. Aspen transmission fixed my leak that I had, worked overtime. I can’t thank this place enough. I HIGHLY RECOMMEND THIS PLACE FOR TRANSMISSION ISSUES! Thank you thank you thank you so much!”
“Steve has been the only mechanic my entire family has used since the 90s. Honest, reliable...busy!! But when I was due with my first baby, Steve worked overtime to get my transmission rebuilt and fuel pump replaced while I was in the hospital so that I would have a car once my husband had to go back to work in TX. He is the only person we will let work on our cars!!”
“After picking the wrong builder THREE times, I finally came to Aamco, and let me tell you!
My experience overall was amazing! Randy is great and my transmission has never felt better! AND they made it affordable!! I am SO thankful for these guys!”
“I recently had my car serviced and the experience was exceptional. From the moment I dropped my car off I was impressed by the hospitality. I was greeted by the owner and he attentively listened and diagnosed the issue with my vehicle.
Joel the mechanic, took the time to explain the problem in detail and was very transparent about pricing. The repairs were completed ahead of schedule, and the cost was exactly as quoted—no surprise fees. What stood out the most was the quality of work and the unreasonable hospitality from the staff; my car has been running smoother than before taking it in.
Overall, Sinclair’s is top-notch service with a personal touch. I highly recommend them for anyone in need of reliable and honest car repair.”
“Have used 2 times now, he was able to fix both of my problems, where as everyone else wanted to rebuild the tranmission, very honest shop. I will not use anyone else, wish I knew about him years ago, good tranmission guys are hard to find”
“If you’re going to a dealership for maintenance or repairs, you’re doing it wrong! I recently had a complex issue on my M6 BMW and they took the time to bring me into their shop to show and explain their diagnostic process. They found the issue in less time than they estimated, and they always communicate extremely well. The next week, I took my Raptor to them for cam phaser replacement and the job was done perfectly. They are able to handle diverse issues and do so with the highest level of quality and service. Can’t recommend these folks enough!”
