Hummer Transfer Cases

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.

It is nice they know what it is like to install transmissions and not just sell them. Good Job Certified!

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 would highly recommend Certified Transmission products to anyone

We have been using Certified transmissions for years and will continue to do so because of the excellent service we receive.

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

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

I am absolutely sold on the culture and professionalism of the company.

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.

Not one time that I can remember have we ever had any issues what so ever with any of the transmissions that we install from Certified or have had Certified Transmission install for us.
