Our Commitment to You

Free Customer Towing Service

Free towing is just one of the ways we strive to save you money on a major in-house repair such as a transmission rebuild. With our thorough TrueTest™ Inspection process, you will fully understand what is wrong with your car and only pay for the repairs you need.

Free TrueTest™ Inspection

Every transmission repair should start with a thorough and accurate diagnosis of the problem. Our multi-step TrueTest inspection procedures have been designed over decades to identify whether a minor repair can fix your issue or if a major repair is required.

Fast Transmission Services

We can turn around a transmission repair in as little as 2 days with our fast services! Our in-house rebuild department, expert technicians and strong vendor relationships help us get vehicles fixed ASAP. It also helps to have two local repair shops with identical operating procedures and quality standards.

Comprehensive Warranty in Denver

After a major repair, you can take a breath and know Advanced Transmission Center has your back! We offer various warranty options (1-year, 2-year, 3-year, local or nationwide) and make sure any warranty claim is hassle-free for our customers.
