Was given the contact info to Roy from my neighbor. The transmission on my 2014 Infiniti blew out and I was in dire need of a new/used tranny. The quote was by far the fairest price I received after contacting multiple transmission shops. After submitting my deposit my vehicle was repaired a week later. Great fast reliable service! Five stars. read more

Frank was great, absolutely recommend Roy's transmissions. Rebuilt my 68 mustang c6 and so far great response

Frank is the owner of Roy's, he has been extremely flexible with arranging a time for me to bring my vintage Mustang, Very professional & easy to deal with on the phone. You pay for a diagnosis, but that is deducted if you get your car fixed there - which I think is very fair. You will pay a deposit up front before they work on your car, but that also makes sense. I also like that the cars are locked inside safely & it's a good part of the city. I also talked to one of his mechanics, very helpful. Shop looks organized, quite a few bays for multiple vehicles. read more

I wish I would have went to this shop first, I would have saved money with having a proper diagnosis the first time around. Thanks to Frank for getting me back on the road commuting to work. read more

I found this place on yelp. I immediately got a great feeling after having gotten the runaround at other places. They were knowledgeable they knew exactly what was wrong. Provided a fair price and a great warranty. If the unfortunate situation arises that I need them, I will definitely use them again. read more

You have been warned: DO NOT TRUST THIS SHOP. They replaced my 2004 Honda Odyssey trans 2 1/2 years ago and it stopped shifting gears (under 30k miles since Roy's replaced it). I went here because they had good reviews and the shop I trust was too busy and couldn't get to it for a couple weeks and I couldn't wait that long w/out a vehicle. After Roy's trans failed I went to my trusted shop and found out Roy's had replaced my Honda van v6 trans with an Acura v6 trans (smaller and weaker - one of the reasons it failed). That explains why when Roy's returned my vehicle the trans never did work/shift like the original trans and the trans fluid was WAY overfilled (they probably put in the van's trans fluid amount into the smaller Acura trans). Also, the shifting issues were due to low pressure because they used a cheap aftermarket torque converter which usually only last 2 - 3 years (the other reason it failed). They also bypassed the normal Honda van radiator trans cooler and incorrectly mounted and used the trans cooler that came with the Acura trans instead (because they used the wrong transmission, an Acura trans instead of a Honda van trans). Don't make the same mistake I did by going here, I will never go back to this shop again. read more

One of my friends recommended this shop to me. Since then I've been taking all my cars to Frank. Frank has been very helpful as far as pricing he's willing to work with your budget. This shop has very good service and very honest about their work. I'm very satisfied with the service. read more

Out of a one through 10 experience was a six at best. I have a regular mechanic check out the problem on my transmission and he diagnosed it accurately. My regular mechanic does not do transmissions so he suggested this place Roy's. I contacted Roy's through Yelp and I received a prompt reply. I described the issue through Yelp to the transmission shop and they gave me a price. I knew the price was going to change I knew it I knew it I knew it. Bait and switch from a reasonable price to a price 28% more. It's not about the money - I would have paid the higher price at the get-go. It's about integrity and bait and switch tactics. It was a minor fix and it was the exact problem my mechanic stated. You can only imagine what would happen if I did not have my regular mechanic diagnose the issue for the transmission I had of time...., #BaitAndSwitch Predatory pricing practices read more

I took my Mitsubishi Eclipse GT for a transmission service, and Frank did a great job replacing the fluids and verifying everything works well. I also asked him to check that there are no leaks and that my suspension and steering should be working correctly. Could not be happier with the service. Frank is a very knowledgeable tech with many years experience in his field, besides being a great person. I highly recommend him and this shop. read more

Very nice Roy was great! I'm so happy with their services Chester was very helpful as well recommend definitely next time I have any other issues! read more

Don't judge a book by its cover. Roy's is on the corner of Raymond and Kimberly in Fullerton's industrial area and it looks a little rough around the edges - not that the shop is dirty or unkempt, because it is well maintained. Rightly or wrongly, this is generally the type of place I avoid. I called Roy's because I wanted to get my transmission fluid changed before an upcoming road trip and I was having trouble finding a reasonable shop that had availability. I spoke with Frank who informed me that they were booked for the week. He told me that he could work on it between jobs if I were willing to let him have the car for the day. On the phone, Frank was professional, knowledgeable and polite, so I agreed. Rather than taking all day, Frank had the car done in just a few hours. And his price for doing the work was about half of the dealership's price. He was not the cheapest (one place offered to do it for $75 less), but I think he was the best choice and I'm very happy. I recommend Roy's highly. read more

Frank does such a great job and promises to be done when he says. I had take my 2016 Suburban to my local auto care location due to issues with the shifting and a loud noise. They told me it was a bad vacuum pump so $600 later I got the car back and initially it wasn't making the noise but as I drove it up hill, the noise came back and it was still shifting weird. I ended up taking it to Roy's and Frank diagnosed it and got it fixed. He is a true professional and I'm a happy customer. Thank you Frank and team I will be bringing my vehicles to only you now. read more

Great guy that I talked with , knowledgeable don't try to pressure me to rebuild but gave me some sound advice on how to proceed. If I do eventually need a rebuild I will use him read more

Took my 1971 van here for a neutral safety switch issue. Frank found OG parts and out it all back together like new. Can't find this type of service easily these days. Everyone wants to do the easy thing and order new cheaply made replacement parts. Frank knows what's best! read more

My husbands work truck's (he is self employed) transmission went out while driving to check a job for work the next day. He called Roy's Transmission at 2:30 in the afternoon and asked if they could look at his truck, they said to bring it in and they would take a look at it. The owner Frank test drove it and said the transmission was toast. My husband told him that he needed it for work and when could he get it done. Frank told him that they would work late and get it done by the next afternoon. His truck was up and running by 2 o'clock the next day, which is unheard of. Roy's transmission and Frank went above and beyond to get his truck up and running and him back to work. We highly recommend Roy's transmission to anyone looking for an honest, reliable, reasonable service. Thank you again Frank read more

Frank is a true pro over at Roy's. Was very informative of the issue on my truck, gave a fair estimate on the fix and did a great job on my transmission. Will definitely go back for any services that may be needed in the future! read more

He tells it like it is and he's very reliable. Finished before he initially said he would have my truck done! Definitely recommend

Frank runs a good operation. He is a very friendly guy person showing respect to his customers. He did a great job rebuilding the transmission on my '67 GTO. Today, he went over my transmission in my 2003 Chrysler van. read more

I had my car towed to my regular auto care provider who quoted me WAY higher than Roy's. We had been using them for our fleet vans for many years, but this was the first personal vehicle that needed a complete rebuild. I appreciate a company that does what it will say it will do in the timeframe and cost estimated. I also appreciated the regular updates on the service (about 3 full business days turn-a-round). After the rebuild, my car is running more smoothly than ever and my mileage has increased by at least 15%. Thank you to all the great people at Roy's for fixing my transmission, and standing by their work. read more

The transmission in my 2013 Ford Fusion Titanium didn't feel right for a few minutes after driving around a very hilly area on one of the hottest days this summer. It felt as if the 3rd gear slipped twice, which is something the transmission had never done before in over 5 years of ownership and 90,000 miles traveled. My first guess was that the transmission got a bit too hot on that day, but I knew it had to be checked by an expert. Transmissions are complex devices and very expensive to repair/replace, so it's best to fix any and all minor issues before they turn in catastrophic failure. So, I took it to Roy's transmission and told Frank about the issue I had experienced. I spoke with him and told him that I wanted a transmission cooler installed and an ATF flush/refill. In the end, the cooler wasn't necessary as the factory one appeared to be functioning well and should be enough to keep the transmission within normal operating temperatures. But what it needed was high-grade ATF and friction modifier, according to Frank. I've been driving the car for about a week and a half and the transmission is working as expected. It does exactly what it's supposed to do without any problems. It's still a bit early to claim victory, but so far so good. Frank was honest and provided an actual estimate range (worst/best case scenario) based on the symptoms I provided. All other businesses either required more information or asked to see the car before a quote could be provided. The whole process was very simple and straightforward. And most importantly, the fix was effective and the price was very reasonable. I'll update my review in a few months after I have driven the car for a few more thousand miles. read more

Roy's Transmission Service - 2013 Ford Fusion Titanium: ATF Flush/Refill + Friction Modifier service performed by Roy's Transmission. - Auto Repair Near Me - Fullerton, California

My transmission has been acting up lately. The dealership told me to do a transmission service for $300. I wasn't convinced a service would fix it so I brought it to Roy's. Frank squeezed me in and checked it out. He didn't find and issues and cleared a few engine codes, but told me a service wouldn't fix the issue, rather it is probably getting old. He told me, If the issue gets worse, I might need to replace it, but in the meantime, save the $300. The best part, he didn't even charge me for the evaluation. What a great service. Much appreciated. read more

My family has taken 2 cars to Roy's so far and we are extremely pleased with their honesty, knowledge and reasonable pricing. Friendly service is another reason why we'll recommend this shop to anyone needing transmission service. read more

It's not often you enjoy paying to have your car repaired Frank was great to work with Honest fair prices and done early He's my new "tranny guy" Definitely recomend read more

Great work by Frank & crew. When I inquired, Frank responded quickly with a reasonable quote. When I dropped my vehicle off, I was greeted by a very nice and knowledgeable mechanic named Chester. He gave me all the information I needed regarding my transmission service and was very pleasant. After the work was finished, Frank was very clear in his explanation of the service. He also made some suggestions on other work I needed done and referred me to a specific shop. In all, felt really good about bringing my truck here. Will continue to come back for other servicing. read more

I base all of my reviews on quality of product delivered and customer service. Roy's Transmission is the only place I will take my transmission. The owner Frank is top notch! Not only is he knowledgeable on transmissions, but he treats his customers with dignity and respect. Recently I decided to install my freshly rebuilt transmission and broke an internal part. I removed the transmission and took it back. I explained the problem and Frank knew exactly what I did. He tore the transmission down, repaired it, and reassembled. Any place else I would have (And probably should have) been charged (+ or - $1K). Frank waived the fee and showed me how to prevent the damage when reinstalling. I reinstalled my transmission as directed and it went in smooth as warm butter. I cannot thank him enough for his understanding and education. You're not going to find too many people who are as honest, knowledgeable, and overall a good person as Frank. He saved me through these tough times and I will forever be greatful. This is why so many car collectors and enthusiast choose Roy's Transmission. A+++ service and second to none. read more

Only place I would take my transmissions to. Never have to question his pricing. Answers any questions I have promptly read more

Roy's Transmission Service - Auto Repair Near Me - Fullerton, California

I was told that the noise in my car was not the bearing but the transmission. So I took the car into Roy's Transmission Service to have the transmission repaired. But Frank found that the bearing were bad and fixed the issue without having to replace the transmission. He went the extra mile to check out the cheaper solution. Great service! read more

My 66' Chevy was in a wreck about a year and half ago and ended up ruining my transmission/engine, needing to swap out my 327 for a 305 and my 2 speed powerglide transmission for a 700R4 Transmission. The whole situation was unfortunate but luckily enough, my mechanic has been super helpful throughout the process. Due to 700R4 needing some extensive throttle valve work, I was referred to Roy's Transmission. I AM SO THANKFUL for Frank's willingness to make room for me at his shop and help resolve the issue I was having. Honest man, friendly as can be and I can trust he knows what hes doing being in the business for 20 years. The transmission shifting and engine response is absolutely beautiful! I will definitely recommend him to anyone that needs transmission work. THANK YOU SOOOOO MUCH! read more

Well, I never thought I would write about any company but after the experience I had with Roy's Transmission in Fullerton, CA I felt like I owe it to them. Frank is one of those guys when you meet you feel he is on your side. I have a rare muscle car and to find a mechanic that can be trusted is challenging. I am so surprised at the quality of work and the time frame in which it was completed. I have been disappointed in the past when it came to help with my 1972 Australian Ford XA Falcon.( The Mad Max Interceptor Car ) Every one says they can get parts and fix problems but with a car like mine, easier said than done. I will be recommending Roy's Transmission to every one I meet at car shows that I go to and share my experience. The price I paid was so reasonable and to my surprise AGAIN when I presented a 10% discount coupon I was expecting them to say "not applicable" But they accepted it. Thank you again Frank and the team at Roy's Transmission Mad Rafa, Main Force Patrol read more

I came to Roy's and worked with the owner in diagnosing my issue. I was told it was the Trans and after his diagnosis he determined it was an exhaust leak!! Such an honest company, when I'm ready for a transmission I'll be back. Highest recommendation!! read more

I will be succient and comprehensive in this review. I have never left a review, but in this experience one is unequivocally warranted. I stress, if you want exceptional customer service and unparalleled workmanship BRING your vehicle to this place. I had an extremely stubborn transmission leak (my personal mechanic tried 5 times to fix the leak from multiple facets). A reputable transmission shop was my last option. After taking my truck (95 22RE) to a few well known shops for an estimate, I decided to have Roys give me an estimate. I can verily see why they have such grand reviews. The first time - they resealed everything lower in price than Leon's (Garden Grove) and a reputable AAMCO (Orange). Side note - (A reseal was what every shop ascertained was needed to fix all my minor leaks). After Roy's did the reseal, unfortunately the transmission still leaked a small amount (over drive solenoid was faulty, even though my mechanic changed it with a new one). Of course in the reseal they also replaced the two O - rings on the solenoid but there was still a leak somewhere. I called them back and told them it is still leaking somewhere, without any issue they immediately took my Truck in to see why. They spent a diligent 2 days diagnosing the esoteric problem and found out why it still leaked. They replaced the faulty part free of charge. After I got it back, I kept looking underneath thinking no way it is fixed (was the seventh time someone had touched it), but to my amazement it has never leaked since, dry dry dry! It is such a relief that they took the time to figure out why it still leaked and then replaced the problem even though it ate into their profit and time. Amazing exceptional experience here. God bless them and may this shop stay open a long time because it is almost impossible to find a honest automobile shop that shows respect to the customer and gets the job done. I am sure the other well known shops would have added an additional charge for the solenoid and made me feel like they are doing me a favor. read more

These guys were so fast in fixing my husband's Tahoe! Very nice people and the truck runs great now. We dropped it off on a Thursday and picked it up on the next Monday. Reasonable pricing too. Thank you guys! read more

I've had two transmission repairs done by Roy's. After the second repair, I started having problems with the car not moving from a start. The issue was VERY intermittent and numerous attempts by Frank to have the problem occur while they were test-driving it, didn't happen. Finally one day I started having problems again so it was back to Roy's. Frank test drove the car and it finally acted up :) Hurray, vindication. They took the car back and pulled the transmission and went completely through the transmission again. The problem turned out to be the pump in the trans and maybe a seal that was bad. I have nothing but praise for Frank and Chester. They're both "good guys" and have done all they could and more to resolve the problem. I highly recommend them! Thanks Guys read more

Awesome, brought my Dodge Cummins in to get the trans rebuilt. Let them know i had a trip coming up and asked if it could be done in time. Frank pulled through and made it happen. Great people, great service and reasonable pricing. read more

I've been going to Roy's for years now and I always get great service and I believe to be very fair (to low) pricing. Compared to other shops I trust and believe that the work Frank recommends I really need. It always surprises me to see old classic (show quality) cars to the latest model vehicles, they seem to be able to do it all. Oh and if they cant't at least they tell you rather than try and figure it out. read more

Frank - your shop is the best! We always can rely on your knowledge, speed, and honesty to keep our vehicles in top-notch condition. From simple oil changes and service, to full-on suspension and brake repairs -and- of course transmission diagnostics and overhauls, your team is unsurpassed! I wish your shop was closer to Long Beach, but it's always worth the drive to know our cars and trucks are in such capable hands. Thanks!!! read more

Great shop! They rebuilt my 47RE in my 2002 Dodge Ram 2500 with a 5.9 Cummins in 2 days. Upon discussion with Frank, we decided to do some upgrades while the transmission was out - mainly a billet torque converter. My tranny had gone downhill gradually over the years (224,000 miles to be exact) and was in need of help. I didn't realize just how much until I got it back! WOW! What a difference! It feels really nice and smooth, shifts nice and feels tight. Price was right in line with where it should be, service was great, Frank kept me updated throughout the rebuild and it was done way quicker than I expected. I will definitely bring my vehicles here for work in the future even though I am coming from Long Beach and this shop is in Fullerton. read more
