One feature that sets our shop ahead of others is our exceptional warranty options. We offer up to 5 years or 100,000 nationwide miles on major repairs for most vehicles. This is one of the best warranties in the industry and ensures you drive away with confidence. Ask for details!
What Does This Transmission Warranty Cover?
Our comprehensive transmission warranty covers specific parts. We will proceed with any repairs needed that are covered by your warranty and advise you in advance about anything that isn’t, so there are no surprises!
What Components are Specifically Covered in Our Warranty?
