Transmission Repair near Castro Valley, CA

“Came to Stress-Free Auto Care with the check engine light on my 2017 Jeep Grand Cherokee. I had already scanned the car and knew the codes:

P0456 — EVAP system very small leak detected
P0440 — general EVAP system fault

I expected it to be a relatively simple fix. However, during their thorough inspection, they also discovered a coolant leak from the water pump weep hole. I’m very grateful they caught it before it developed into a more serious problem.

They addressed the check engine light by replacing the Leak Detection Pump, and the coolant leak by replacing the Water Pump and performing a coolant exchange.

After I picked up the car, the check engine light unfortunately came back after about 20 miles of driving. I returned to the shop the next morning. This is where I particularly appreciated how they handled the situation.

They took responsibility, found room for my car despite being very busy, performed another inspection, identified an issue with the EVAP purge line, and replaced it at no additional charge.

Things don’t always go perfectly with automotive repairs, especially when diagnosing EVAP issues. For me, what matters is how a shop responds when something needs further attention. Stress-Free Auto Care handled it professionally, stood behind their work, and made sure the issue was addressed.

Overall, a very positive experience. I appreciate their thoroughness, communication, and willingness to stand behind their work.”

“Although I have not had my car serviced here. I can say their customer service is excellent. I have emailed and inquired about getting a motor swap done to my car that went back and forth. With other shops ignoring my emails, Boulevard Auto went above and beyond to take care of and answer all my questions in detail with great insight and advice. I wouldn’t hesitate bringing my car to them when I’m ready to have the work done.”

“Had an amazing experience here! I took my car somewhere else for a tune up and they suggested a ton of different fixes that would have amounted to a total of 7k! I brought it to Cat's for a second opinion and got a much better deal, plus a better understanding of what my car needs and doesn't need (since I only expect to use it for another couple years). Plus my car finally sounds normal now after years of loud exhaust sounds. Thanks Cat's!”

“Auto Doctor has always been very good at diagnosing and fixing any problems I had with my vehicle, they were much better than midas down the street, fixing things much faster, more efficiently, and for better price.

Any problems with previous repairs, they would cover it under warranty without any problems.”

“I travelled all the way from Tracy to have my car repaired at Autoworks European, and it was absolutely worth the drive. My car stayed with them for a full week while they completed a thorough diagnostic, replaced the necessary components, and executed every part of the repair with precision. They used proper OE and OEM parts that match factory specifications, ensuring perfect fitment, reliable performance, and long‑term durability. The difference was clear the moment I picked it up: the car felt smoother, tighter, and exactly how it should. Even though they’re only open Monday through Friday, they went above and beyond by allowing me to come in on a Saturday morning to pay and collect my car since I work full‑time during the week. Their customer service is exceptional, and the owner’s wife - Ranju deserves special mention—she is incredibly friendly, welcoming, and genuinely committed to making the entire experience easy and stress‑free. Autoworks European delivers honest workmanship, quality parts, and customer care that truly stand out, and after this experience, they’ve earned a customer for life.”

“If I could i would give them more then 5 stars. I had a great experience with this transmission shop! They were professional, honest, and very helpful throughout the entire process. They took the time to explain what was wrong with my car, what needed to be repaired, and made sure I understood everything before moving forward.

My car is running great now, and I really appreciate the quality of the work and how quickly they got everything taken care of. It’s hard to find a repair shop you can truly trust, but I would definitely recommend this place to anyone who needs transmission work . Thank you for taking such good care of my car!”

“So it’s been exactly 1 week since I got my car back from the shop ?I had an electrical issue. (Wires)When I would press the start button to turn off my car, the engine wouldn’t shut off right away. It would take a few minutes. It would shake until it would force itself off… then my headlight would turn itself ON. (Yes, the lights were OFF) So b/c there was no other way for me to turn off, a button that was already off.. it would kill my battery… which would make me jump my car every other day when it wouldn’t turn off properly.Anyway… I had already made an appointment at a Ford dealership in San Leandro for an oil change.. then I included the issue above. I had my car there for a lil over a week, I spoke with him the weekend after drop off (monday), and the day of pick up (the next Monday). I couldn’t get a hold of him throughout the time my car was getting looked at.I called & spoke w/a few other ppl then I eventually spoke w/manager who told me he would get the guy assigned to me to reach out, which he never did. When I picked up the car, they said they couldn’t find anything.A day after, the car started doing the same thing, I dropped my car off after hours (b/c of work)Spoke to someone new, asked for someone different for the lack of communication, the new guy didn’t like that so much, so I took my car to the Ford dealership in Fremont,They ran another diagnostic (2), they too said they could not find anything, but that my oil was over filled & that I needed another one (drain out and put new), something about a lid under the hood needed fixing which would cost $1800, and I have bad tires in the front. They too had issues with communication, but it was kinda better then San Leandro..+ it was there a lil over a week b/c I had to wait 3 days for someone to run a diagnostic ?I honestly felt discouraged, and I didn’t know who to trust.Then I went ahead and took it to Managal Motors, because I remember having a good experience with my rotors getting replaced a few years ago.I called in, I dropped my car off the day of. I was told that they were going to run another diagnostic (3) and that it would take some time to find out the issue of the car. They called for questions about it before working on it, plus called in again to let me know what they were doing, and what he thought the issue might be, and then I got a text of a receipt & a call it was ready. I dropped it off before their shopped closed on a Tuesday, and got the car back on Monday (they had it fixed less then a week!)I haven’t had any issues with the engine turning off, or no spooky lights turning on by itself since ☺️☺️☺️☺️ & I was also told about my bad ties in front. (Which I did know about, I had my back tires changed, and I was working towards the front… anyway) I felt like they actually took the time out to find out what was wrong w/ my car, & kept in communication, and my car wasn’t even with them for a whole week.I’m not sorry for the long review, I’ve been really frustrated with the lost of money,time and lack of communication and trust. I’m so thankful that my car is back up n running.? THANK YOU MANGALE MOTORS!!!! I HIGHLY RECOMMEND!!!Ps. I had some burnt wires (from a car accident) that needed to be replaced, and the total cost was $537.69Which includes a diagnostic, parts, & labor.”

“I came in last minute first thing this morning with a flat tire, and they took me in right away and got everything taken care of so quickly. I’m a student and had an exam that morning so I was already stressed, and their kindness truly made my day. I can’t thank them enough and will definitely be coming back when needed! Thank you to Larry and his team!!”

“Bruce's is the place you want to go if your tire is low or if you have alignment issues. They are freindly clear and honest.
The guys are always helpful and really are kind as well. I have been taking my cars to Bruce's for almost a decade now and have only good things to day about the team!”

“I had originally taken my car to another car repair shop who gave me an estimate for the work needed. I decided to get another estimate and had called Brannan Auto Experts (5 star on yelp) and spoke with Kevin who gave me an estimate over the phone which was much less than the original estimate. I brought the car to Brennan's for repair and although the total cost went above Kevin's estimate, it still was less than the original estimate. Kevin explained to me why and it was understandable. They had to keep my car for 2 days so Kevin suggested to rent from Hertz nearby who they had a relationship with and would give me a discount. I have full confidence in Brennan Auto Experts. I believe they are honest, knowledgeable, and courteous. I will be bringing my cars to Brennan Auto Experts from now on.”

“This is the best transmission shop I have ever been to. Fast , reliable, and good prices. Thanks for the excellent transmission swap on my 2016 Cadillac CT6. Ty quoted me on Friday Said bring the car on Monday morning had it back to me Tuesday afternoon running like a champ thank you very much!!”

“Peter was super friendly and handled my smog-related issue very quickly. He explained what he had to do and the pricing upfront and the cost was very reasonable. Highly recommend this place!”

“I had an issue with my car and Dan was able to have us scheduled within one day- he personally corrected the issue within minutes and even checked the oil and topped off the wiper fluid. Additionally, he wouldn’t charge for the service. We had a great experience and highly recommend!”

“Although I no longer live in the Bay Area, I want to highlight my experience with Kevin & Conner's shop. If I had to choose one word to describe working with Kevin, it would be HONEST. He never tries to upsell unnecessary services. For example, when my previous vehicle (an Audi with just over 100k miles and high maintenance costs) started giving me trouble, I asked Kevin for his advice. He gave me a straightforward, neutral perspective without pushing me in either direction.

If you're looking for a mechanic who lures you in with a low estimate only to surprise you later with unexpected charges, this is not that place. Kevin is upfront, reliable, and trustworthy.

Over the years, he serviced multiple vehicles for me and even helped me purchase a new car. If I still lived in the area, I would not hesitate to go back.

The only con is that they are busy which is a byproduct of several years of goodwill.”

“I had the best experience with Nayarit Transmission shop! Marcos was extremely helpful and explained in detail what I needed and what he was going to do to fix my car. He completed the work in 1 day! He was very nice and professional. I highly recommend using them especially for women because he is trustworthy and charged fair price ? !”

“Incredibly helpful staff and very friendly. They explained all of the details of the issues found, costs involved and breaking it down to individual components and labor so everything is totally transparent. Very highly quality work and to say it again, very helpful and friendly.”

“Take all my cars here for regular maintenance and more serious problems. They always get to the root of the problem and what is the best fix. Best part of every transaction has been the honesty and we all know how hard it is to find an honest mechanic. Would recommend to my mother! Great shop!”

“Really glad I found this shop. I spoke with David Jr on the phone. From day one he was helpful. He and his team there listened to me about an issue that was hard to simulates unless you can hold 60mph consistently. Hard to do in bay area afternoon traffic. We all agreed on what we thought was going on. The team there put in the extra effort, and the turn around was great. The truck is driving better then ever now.”

“I been bringing personal and work vehicles to Sam for years now. from simple oil changes and breaks to transmission swaps.

He will personally view and work on each vehicle and will communicate with you along the way if its complicated repair.

He's honest and fast. I believe he's expanding now and offering tire services.

You won't go wrong with SMC.”

“It's pretty rare that I post a review because im not easily impressed, however, I took my mother in laws older Lexus in to these guys. They were friendly and quick to check it out. Called me that day and went over what they found. I was quoted a fair, reasonable price and they didn't give me the run around trying to gouge me for unnecessary repairs. Car was fixed the following day at the price they quoted. I would absolutely recommend using them for your auto repairs.”

“This marked my first visit to Mark's Transmission, now formally known as MTS Transmission, and I must admit, I've never had a better experience dealing with mechanics. Initially, I took my Jeep Wrangler to the dealership, where they proposed replacing the entire rear differential at a steep price. However, upon a recommendation, I visited MTS Transmission, and it turned out to be the best decision I could have made. Mark was exceptionally pleasant and patient. He took the time to inspect my Jeep thoroughly and provided a detailed explanation of the issue. Contrary to the dealership's recommendation, it was determined that my Jeep didn't require a full rear differential replacement, but rather just the rear differential carrier, along with the installation of new side bearings and rear axle bearings, which resulted in a much more reasonable overall cost. I will certainly return in the future. Many thanks to Mark and his team for their assistance and efforts in getting my Jeep back on the road.”

“Matt, Michelle and the rest of the team were fantastic. Professional, easy to deal with, straightforward and honest. They keep me in the loop as they successfully negotiated with my insurance company.

The work was to fix a damaged front bumper on a Tesla. The work and paint job are exceptional. Looks incredible. They also determine that the car had a protective film on it. They had the replaced as part of the project (something I forgot about).

Well done D&S”

“Nabi is the most trustworthy mechanic we've ever had. Not only that, he is a wonderful, personable, gentle, and hard-working man with outstanding morals - just what you want in someone you trust your car to. I want to keep him all to myself, but he deserves another good review because he's the best there is. Fair prices, great and quick service, quality work. Nabi is # 1!”

“Been coming here for years! The least I can do is to leave a great review for this man! Other places would already be charging you without even checking your car yet. Most honest Mechanic I’ve ever met! Real stand up guy!! Appreciate you always, Mike!”

“Extremely knowledgeable. Very friendly. Have experience and parts for transmissions back to the 60's. Sorted me with a torque converter for a 60's Mercedes.”

“These guys are great. I brought in an old crusty Ford ranger with an intermittent no start problem that could have been a thousand different things. They were very thorough and honest and ended up fixing it for only $300. I would highly recommend this place!”

“I came in originally to have my transmission fixed (my car could not go in reverse). Mike made a great impression from the beginning. He was courteous, friendly, and very helpful. In addition to fixing a stripped gear he also noticed a bad bearing and replaced that as well. The price was also reasonable. In addition to that he fixed a leaky oil pan and did other general servicing on my car. When I had a problem getting the car smogged due to no power in my OBD 2 port; Mike went above and beyond to help me resolve the problem. Because of my experience I will highly recommend Walts Transmission to my friends and family!!!”

“Joe told me the absolute truth about my car that the dealership wouldn't tell me. He did not take advantage of my need to get my vehicle running. He was also done when he said he would be.”

“Great place, fixed a seal in my transmission (that I removed and brought it) in about 5 min. Definitely the place to go if you need repairs. I would highly recommend coming here.”

“They rebuilt the transmission on my Honda Accord 4 years ago, for a fair price. The transmission is still working smoothly today. I was worried it would've been a big waste of money if the rebuild failed after 1-2 years. Looking back, it was worth it and they did a good job.”
