Called in for a quote and was very unpleasant answering my call. Plenty attitude when I just needed a quote to see how much the cost would be. Not sure what kind of business he running with that type of customer service. I wouldn't recommend anybody I know to here read more

Normally I'm not one to leave reviews, and this is actually my first time ever posting one on Yelp -- but I HAD to share our experience because integrity like this is rare nowadays. My husband and I had been dealing with a persistent noise during deceleration in our 2011 Toyota Camry for over a year. We took it to several shops, spent a few thousand dollars fixing "issues" that turned out to be unrelated, and still had the same problem. We eventually figured out it was coming from the transmission -- yikes! We went to another transmission shop (which I won't name), and after multiple visits and some shady back-and-forth, they quoted us $9,500 for a replacement transmission and wanted $6,000 down just to order it. Weeks later, they claimed the transmission was "lost in shipping" and offered to rebuild it for nearly the same price. Something just didn't sit right with us. That's when I decided to call around, and Certified Transmission Differential was the first shop that actually answered. I spoke directly with the owner, Tracy, and explained everything. Even after hearing what I was quoted elsewhere, he stayed honest -- no upselling, no games. He quoted me $4,500 for the rebuild, less than half of what I was about to pay! From start to finish, Tracy went above and beyond. He opened early so we could drop the car off before work, kept us informed every step of the way, and even showed my husband the damaged parts he replaced. He was incredibly knowledgeable, straightforward, and fair -- even buying another transmission just to get a rare part without charging us extra. In a world where so many businesses overcharge or take advantage of people, Tracy and his team restored our faith in what honest work looks like. Our Camry drives beautifully now, and we finally feel peace of mind knowing the job was done right. If you're looking for a trustworthy, knowledgeable, and fair mechanic, go to Certified Transmission Differential. Tracy has absolutely earned our trust and our future business -- I can't recommend this shop enough! read more

Went here to pick up a transmission with a buddy. The place seems honest and fair. He knows what he's talking about.

On Thursday, 10-1-2020, my clutch was going out on my 2012 Nissan Frontier. Certified Transmission opens at Mon to Fri 6AM-6PM I called at 0600 hours spoke to Tracey and he gave me a good price to replace my clutch and Resurface the flywheel. My truck was ready the next day at 0930 hours. read more

It can be so hard to find someone to trust with a vehicle now a days. But the guys at certified trans are not only trust worthy but highly professional and experienced mechanics. Super thankful for them. I would highly recommend them. read more

Let me be the first to review this hidden gem. The boys at CTD are trustworthy, straightforward, and extremely experienced. They stand behind their work and are stubborn problem solvers, never giving up until the job is fully complete. My transmission for our Chevy work truck was making strange noises, old (2004), and dying rapidly so I needed a new transmission built. Tracy ordered parts, went to work, and got it done expeditiously. He was patient whenever I had any questions regarding parts and labor. This is important, in my opinion, considering transmission work is not what everyday people consider to be common knowledge. In addition to transmission work, he and his business partner, Braddah, changed out two broken CO2 sensors and inspected the rest of my vehicle to make sure there weren't any other notable issues. After I got my truck back, they followed up with a phone call to ensure there were no setbacks after I drove it around. Small gesture, but much appreciated. There are no other reviews as of today, but don't let that scare you. Braddah and Tracy were both previously employed by other shops for over two decades with a wealth of experience in engines and transmissions and finally saved enough on their own money to open up their own shop. I'm going to enjoy taking all my work and personal vehicles there before they get too busy some day. If you're on the fence, give them a chance. You won't be disappointed. read more

Clutch went out in my Cayenne, I called every transmission shop on the island and most guys would not touch my car with a 10' pole. Some guys even tried to clown me and tell me Cayennes dont come in manual, like Im some kind of ding bat, but Tracy was up for the challenge. He quoted me a price that was fair and did what he said he was going to do, and it didnt take forever. These guys are highly recommended. I think its worth mentioning that his pricing was so honest and fair that I was actually shocked. When i picked up the vehicle, they showed me the broken parts they had replaced, and explained every single thing right down to a tiny spring. I had already priced all of the parts and so I know that he barely did any markup at all, which is not the norm and I greatly appreciated. When my car was ready I could not believe how well it drove. Its like I picked up a different car than what I dropped off. I wanted to fix the clutch to sell the vehicle, but after i picked it up, i feel like i should keep It. The car is solid and drives so well and I owe it to these guys. Honest. Fair. Absolutely recommended. read more

Tracy was very informative on what needed to be done and showed me what needed to be repaired before handing my truck over to complete the work. He also replaced the main bearing seal since he had the torque converter removed during repair. Transmission works great! Mahaloz Tracy read more

Had to write a review for this business because they were awesome! I had been driving around for almost a year after Lex Brodie (Queen St) changed my tires and did the alignment. It had been making a loud noise, like a jet engine, so I took it back and they couldn't find anything wrong. Fast forward 9 months later and the sound got noticeably worse. Friends thought we were taking off on a flight everytime I went on the freeway. Took it back to Lex Brodie on a Friday and they said it was "probably the exhaust system". They could run a diagnostic for $198 but they don't fix exhaust systems. Ok, so on to Midas (on Dillingham) I went. The next day (Saturday) I dropped it off and they said they'd "check everything" and call me with an estimate. I got a call about 4 hours later saying it wasn't the muffler. Do I want to check anything else? The guy who called sounded extremely high. It sounded like the same guy I dropped my car off with. He was now talking really slow, and didn't know I wanted everything checked. So now 3 hours later he calls again and says there's nothing wrong and I can pick up my car. It's Monday now. Since I recently did a safety check at another shop, I called that shop and they referred me to Tracy at Certified Transmission. I spoke to Tracy and told him the problem. He made me an informal appointment to just bring my car in so he can take a look. Took it in and he immediately "guessed" it was a wheel bearing in my front tire. And I mean immediately (within a minute). OMFG! Needless to say he worked on it and I got my car back before I ended work! Fast, professional, reasonably priced and no stress!! Tracy is the best!! I'll be taking my car there and ONLY there for whatever work he can do. I almost didn't want to write a review because I don't him getting so busy he doesn't have time for me. read more

My truck began driving poorly, seemed to have a hard time shifting when accelerating. I figured my transmission was acting up. I called and got an appointment to bring my truck in. Scheduling was very easy and this was one of the few companies that answered their phone every time I called. Within a couple minutes of arriving at the shop they identified that what I was actually experiencing was an engine misfire, not a transmission issue. I appreciated the honestly of this company and not performing and charging for an unnecessary repair. Should my transmission ever actually fail, I will be calling them again. read more

The guys at CTD are awesome. They take the time to figure out what is wrong and stand by their work. Great quality work at a reasonable price. People need to give these guys a try. Bruddah worked on my vehicle and I got it back by the end of the day. With a name like Bruddah, you know he is an honest guy. Haha. Car is running great, Thanks CTD read more
