    Detail. Competence. Helpful tone…read more Good explanation of the services and options. Fair and transparent pricing. Reputable.

    Although I appreciate that they didn't charge a diagnostic fee, I'm really disappointed with my…read moreexperience. I brought my car in due to an intermittent gear slipping issue, which I had already traced to a solenoid problem--a very common issue with my Pontiac G6. The symptoms only occurred twice, very briefly. My check engine light came on both times but turned off on its own. I was still able to drive the car on the freeway at full speed with no issues. The problem only showed up during city stop-and-go traffic. I specifically asked if they could just replace the solenoid, and was told no. Instead, I was told I "only had gears 1 and 2" and that I'd need a $4,800 transmission rebuild--which is objectively false, as I literally drove the car 70+ mph on the freeway both before and after leaving the shop. My engine light was off before coming to the shop, turned on once at the shop, then turned back off shortly after leaving. There is no way my car had only gears 1 & 2 I know what that feels like as it happened twice briefly. So to say this to me is insane. Mind you wouldn't have been able to go more than 25 with out the car struggling they must have assumed I don't know a thing about cars. Possibly because I'm a woman and I went alone. They also claimed the solenoid was too difficult to access without replacing the computer and warned me about my car's mileage, as if that meant it wasn't worth fixing. But then, on my way out, they admitted it's a "really great car" and "this is the only issue." It felt manipulative. I decided to trust my gut, went to a different shop, and had the solenoid replaced--and now my car runs perfectly fine. No rebuild needed. If I hadn't known what I was talking about, they would've gladly let me spend thousands on a completely unnecessary repair. Trust yourself. Do your research. Don't let fear-based upselling push you into something you don't need. Also from reading the reviews it sounds like the routinely tell their customers they need a rebuild and successfully do the rebuild. (more than likely something very easily replaceable) However a good transmission shop doesn't just rebuild, they properly and honestly diagnose and repair. He also tried selling me cars on the way out. Notice how he hasn't replied to this yelp review and also told me he feels bad for me in the text? Very unprofessional I don't need your pitty I needed honesty which I didn't get from this shop. He also told me don't buy a used car you can't guarantee you won't have problems it's best if you fix this one with us. Also told me not to go to another shop because id want a local shop lol

It's was leaking transmission fluid, had a rattling noise and first gear lag. I was told it was the transmission but I wanted a second opinion. Marcos confirmed it was not my transmission and gave me a diagnostic. He is very detailed and honest when explaining diagnostic and providing a detailed quote. After Marcos fixed my car he showed me the new parts and old parts. He is very quick and responsive. Car drives smoother than ever. No more leak, no more rattling and no more acceleration issues. Thank you Marcos for all your help! Your costumer service is exceptional!

    I know it seems that 5 stars is hard to achieve, but this shop reached it quick, fast, and without…read moredoubt. Marcos was a blast to work with; he is truly old school. I had my 2003 Hummer H2 towed in and left there feeling good after the work was done. He walked me through the whole process, you will feel comfort in that; I know I did. I was not expecting him to have my failing parts, but he showed me my parts, educated me on the failings of my transmission, and here is the part that totally surprised me " You can take them with you", no one says or does that anymore. His pricing was reasonable and he added extra services just because he knows it was right; I can promote someone and their business with those criteria and qualities; he has got a customer in me.

    honest & kind, old fashioned & down to earth…read more my truck had this grinding noise. i first had it diagnosed by a SF city's legacy business auto repair shop. they said because noise travel everywhere, so they can't say for sure its source. after advising me to change several parts unnecessarily, eg, axle shaft, etc, the grinding noise persisted. they failed to find its origin. next, i sought help from a Costco's auto program repair shop. they showed off to me how they make use of misc fancy, allegedly expensive diagnostic tools. yet, in the end, it was a waste of time. then, i sought help from Powell's Hydramatic. Sam simply rolled up his sleeves and manually break the relevant components apart. within hours, he pinpointed the source of the grinding noise being the failed propeller shaft, even showed me the heavily grinded parts. therein lies the strength of Sam, old school, he could grasp the problem by understanding how all the parts work as a whole via his 70+ years of experience, and hands on approach to the problem. appears to be a hobby shop for Sam, he still has that spark of curiosity in solving automotive mechanical problems. decades passed, yet he likely is still very much that same young apprentice who first came across Hydramatic transmission when GM first introduced it, not swayed by the greedy and bureaucratic corporate culture of prevalent auto repair industry. and Maria is honest, caring, and resourceful in getting parts for her husband's mechanical hobby. Sam and Maria are honest and competent. and very convenient too to visit because their shop is just 5 minutes walking distance from 16th street Bart station.

    What a great experience. Maria was absolutely wonderful -- kind, patient, and genuinely pleasant to…read moretalk to. You can tell she really cares about customers. I brought in my 2005 VW New Beetle Convertible, and the whole process was smooth from start to finish. The shop itself is calm and quiet, almost like a library -- very different from most auto shops. I was given clear information, no pressure, and everything was explained in a straightforward way. Customer service was excellent, no hidden charges, and the car was handled with care. Overall, a very positive experience. I'd definitely come back and recommend them to others.
