Eh, gotta give props and mahalos to Tracy at Certified Transmission Differential. Had my Chevy Silverado towed in 'cause transmission had no forward gears and Tracy made quick work of the rebuild. Truck is running smooth now, no slippage or issues. Plus, price was cheaper than I thought it'd be. If you need transmission work, this place gives fast, friendly service at a fair price. Would definitely recommend.

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

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.

Tracey is the best transmission specialist. He gave me a quote that is 80% less than the dealer's estimate. He was accomodating as well by getting my vehicle back on the road by the end of day. I hope to not see him again for any transmission issues, but i know he will be honest and fair about pricing during this challenging economy.

Here’s my story about this business. First of all, absolutely amazing service. A while ago my engine light came on, (2017 Dodge Grand Caravan, 42,000 miles) then it went off, then it went on. I went to Artesian Auto, which is the best mechanic shop on the island. Aaron is the shop manager. Nicest, most polite guy I’ve ever met.He tested my engine and saw it was something with the transmission. He recommended I call a place called Certified Transmission Differential. I called and Tracey answered. I told him my symptoms. He was straight to the point and said he has been in business for 40 years and bet everything it was my torque converter. I told my Wife and she said she would feel more comfortable taking it to the Dodge dealership.So I honored that and took it there. $204 dollars for a diagnostic, and they said…you guessed it…torque converter is bad.Here’s the difference between them and CTD:1) dodge was going to put a refurbished torque converter (that’s fine, doesn’t have to be new, just fixed??) into the van, slap it in and call it a day, $2900. Nice, thank you Dodge for giving me another problem in about 30-40k miles. Dodge offers a 2 year, 24k warranty.2) Tracey has a guy who personally rebuilds them and has for about the entire 40 years he has been in business, they never break, AND they add the updated OEM parts to it so it will last as long as a torque converter SHOULD ACTUALLY LAST, which should be about 120,000 miles (or more!) Oh, and Tracey charged me $1361.00. Why? Because it costs x dollars to get the part AND have it built properly and stuff, plus the rate of work on it. He can do things faster and more efficiently but he’s honest and only charges for the work he does because HE LOVES HIS JOB. Oh, and he didn’t have to, cause he said I wouldn’t need it, but for my Wife’s peace of mind, he gave us a 12 month, 12,000 mile warranty. Problem is we are moving off island. He told me it won’t break, but IF something happened, he would ship me the part free shipping for me, and I would just take it into someone else. Awesome.So there you have it. THANK YOU, MAHALO NUI LOA Tracey. I hope you are in business for a long, LONG time.

I called and asked what their rate were for a diagnostic for my transmission-FREE. Tracey was knowledgeable, genuine and friendly. My car was a little more complex and he offered for me to come again to do another scan on my van. I haven’t had any repairs or work done yet…but first impression means everything. Thank you Tracey.

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

Anyone looking for transmission repairs or even general repairs NEEDS to check out Certified. These guys are legit. Tracey and Brahda are the real deal. My AOD trans in my 1993 F-150 took a dump on me, lost drive and OD. Contacted Tracey and he took me right away. And just like that, boom....repairs done right.These guys have decades of experience, technical knowledge, and skills. Honest work at an honest price. So forget rays, kiyos, all trans, and anyone else. Certified is gold in my book. Highly recommended.Service: Transmission

We are very grateful for Certified Transmission Differential - Auto Transmission Repair & Rebuild Service, Honolulu, (we were referred by the Shop Manager Zack at Starkey’s Auto Repair), who placed Customer Service above sales/monetary gain with unnecessary repairs and returning our business delivery vehicle back in a timely manner, (Unbelievably, the NEXT DAY!), at a more than reasonable cost…. It is a blessing to our business to have found a Transmission Shop with such high morals and integrity…. Thank You….JeremyFurniture Now OnlineService: Transmission

I called about my transmission having problems, he told me to come in and he’ll check it out for free. Told me I need some new motor mounts and gave me a great price. I can tell this is a good honest mechanic.Service: Transmission

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.
