Hummer Transfer Cases

our shop experiences extremely low failure rates

The crew at Certified is incredibly knowledgeable, and we would not hesitate to call them for product support, or other technical issues we may run into.

To the point we will not even consider another supplier other than Certified Transmission.

Certified Transmission is always willing to help and solve problems when they arise and each member of the staff that I have dealt with has been fair, reasonable, responsible and accountable. Our government could sure learn a thing or too from Certified T

I am very happy with quality of transmissions and The Road Ripper is great!

Certified Transmission backs the customer. Their warranty is second to none

We have worked with Certified Transmission for over 30 years. I rate their customer service top notch, A+, and a gold star on any warranty work or help needed.

With Certified products new sales opportunities now exist that were previously unavailable to us. The products from Certified Transmissions gives us a competitive edge with their outstanding tech support, look-up system, online ordering, core return and warranty processes. Doing business with Certified is extremely simple.

We love being able to purchase carryout transmissions OR have their shop do the installation for us. Our customers love the 3 year warranty.

I recommend Certified Transmission 100%
