Hummer Transfer Cases

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.

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

Since the beginning it was obvious that Certified Transmission was on the leading edge of technology.

I recommend Certified Transmission 100%

I would highly recommend Certified Transmission products to anyone

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

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.

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

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
