Short and to the point visit. He knew what he was doing and handled it quickly at half the price of the next guy. It was only a transmission quick learn, but Ill definitely go back if I need something else done that I cant do myself.

A very reputable shop referred me to Certified for transmission work, so I took my Explorer to this guy. Owner cant or doesnt want to deal with extended warranty companies and was not willing to take on the challenge. Long story short, he held on to my car for more than 4 months and only called the extended warranty company twice while he had it sitting in his lot. I wouldnt recommend taking any car to him. I ended up going to Hawaii Transmission on Sand Island Access Road who has over 30 years of experience as well as taking on extended warranty companies.

These guys are dependable and unbelievably fair, where pricing is concerned.I cannot see myself using another differential shop as long as these guys are on Oahu.My vehicle is foreign and frankly, a pain in the *ss, and nobody ever wants to work on it. Tracy was not only up for the challenge, but he delivered. I picked my car up a month ago, and it has been nothing but smooth sailing. No slippage. No problems. No concerns. If you are having clutch or transmission issues, I urge you to give these guys a call. You will be so glad you did.

I did Google on best axle repair center in Honolulu and opted for Certified Transmission Differential based on the star rating. I took a risk but am truly satisfied with the kind of services I received. The team is quite professional and honest about costs. Had a great experience and looking forward to working with them for years to come!

A solid place to receive work done on a vehicle. Employees were professional and did the repairs correctly the first time. No upselling on prices which was nice. Quality work and honest craftsmanship all around.
