Hummer Transfer Cases

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.

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

I would highly recommend Certified Transmission products to anyone

I recommend Certified Transmission 100%

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

The timeliness of getting transmissions helps to keep the work flow going in our shop to allow us to keep customers happy and maintain profit.

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

The quality of Certified Transmission products is unmatched, and believe me, we know from experience.

I highly recommend Certified Transmission products and services to any of my customers and peers.

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