Transmission Service Warranty

Our Nationwide Transmission Service Warranty...You're Covered Wherever You GoWe give you the peace of mind you deserve with your transmission repair. Isn't it great to know that once we've fixed your transmission, your warranty will follow you wherever you may travel - anywhere in the U.S., from coast to coast, and in Canada too? That's because when we rebuild your transmission, we offer a Nationwide Golden Rule Warranty good at any transmission repair shop that is an ATRA (Automatic Transmission Rebuilders Association) member.


We offer a Nationwide 2 Year/ 24,000 Mile Warranty on your rebuilt transmission, where we stand behind you for 2 years or 24,000 miles, whichever comes first. We also have Nationwide 3 Year/ 50,000 Mile coverage available. With any of our warranties, your transmission and torque converter are fully covered against any defective transmission materials and workmanship (that's all parts and labor) during the term of the warranty. These warranties also give you coverage at more than 1,700 ATRA member transmission repair shops. So if you ever need help, you'll find lots more places to go for warranty service than any of those other transmission repair chains, even those that claim that they are the biggest!

Our Engine and Other Repair Warranty...

We Stand Behind Our Quality Workmanship


With all our repairs you have the peace of mind of knowing we provide a quality repair that we stand behind. For most repairs other than your transmission, we offer a 1 Year/ 12,000 Mile warranty that covers all parts and labor for the repair performed. Ask us for details and any limitations and exclusions that may apply..


With all our warranties, whether for a transmission, engine or other type repair, we're committed by our Code of Ethics to provide you with honest and expert warranty service, in a courteous and professional manner, should you ever need it. So if you ever have a problem, you know we stand ready to honor your warranty. We're with you all the way. That's peace of mind you can count on.
