I have 2017 GMC Sierra 1500 with 5.3 engine. I had the active fuel management system deleted. They said I shouldnt see a gas mileage change. But Im actually getting 3 mile to the gallon better gas mileage! I had transmission cooler installed and transmission is running about 60° cooler. Cant be more please with the consultation and recommendations and the out come of the work. Thanks!

Very helpful and willing to help me finish my build but the other mech I had working on decided he would finish it up so I didnt have to use tommy Boys but they was willing and ready to help me

Bryan and his brother took my truck told me to expect two weeks to completely rebuild my transmission. To my surprise it took them three day, he also called me once they started the job along with what was the cause of the failure. He answered any questioned I had and told me to feel free to call anytime. There work was exceptional and even thou it was a 2 1/2 hour drive for me I would go back no questioned asked.

They were super nice, fast, and affordable! Will definitely return if I need more work done and will recommend to others.

It took a small amount time to get transmission fluid put into my vehicle. Thanks zTommy Boys

Great service, quality parts. The only place I have a transmission built

Great work, got the job done fast. Highly recommend. Will do my work for now on.

Excellent Service coupled with competitive price. #1 mechanics around.

Came in for transmission work on my 2001 Dodge ram 2500 with a 47re. They were very knowledgeable and gave me their expert advice. Saved me lots of money and time. They do great work highly recommend going here for any kind of transmission work.

Cant say enough about this place. Super informative. Reasonable pricing and always treats you fair. A company that actually stands behind their work. Great group of people

Three brothers run Tony Boys. They all get along. Wonderful service. Professionally done repairs. Not take my cars anywhere else!

Super awesome customer service. Best auto shop Ive ever been to!

Fast, friendly, and honorable service you can trust!
