I brought our 55 Chevy in for routine maintenance and suspension adjustments. All work was done as asked and within the estimate provided. Extra care was taken with a plastic seat cover and floor mat protection which was appreciated as the interior is new. I always enjoy the team at Grumpy's and to see all of the great projects and upgrades the car customers are having done here. Grumpy's has done a ton of work on our car and they have always kept me updated on any challenges and concerns to include any costs associated with finding something unexpected. I have seen other reviews from customers who have faced some challenges Which can be very frustrating, but I have never had this experience. The team at Grumpy's have always been very professional, with great care taken with my car and the work being performed. I just can't see myself not being able to navigate a conversation to a positive outcome with the team at Grumpy's. read more

I read the response to my review. Such a crock of lies! I did not have you checked my vehicle before I bought it. My brother did all of that. So not only is this place full of price gouging and unknowledgeable mechanics, now they are trying to lie to squirm out of how corrupt they are! Never take your vehicle there. They have started stealing customers hot rods too. This will not keep you from going under like you deserve. read more

Let me start by saying, as much as I feel the pain of others who left reviews, I'm just glad I'm not the only one who had a bad experience with this shop. It started out good, but one of the owners was rude and unprofessional on more than 1 occasion, In person and over the phone. She has no business being the face of Grumpy's! She yells at customers, unprovoked, and talks over you, but as soon as you start to answer her, she talks over you again and reprimands you for talking over her. She wont release your vehicle, even tho it's paid in full up front. Then they supposedly ordered parts for my car, yet cannot produce any receipts for the purchase? Not to mention the overcharges, making stuff up to charge me for, just to make it look like they don't owe me any of my up front money back. It seems like some shady stuff is going on there. (especially after reading other reviews with similar experiences) Most of the workers/mechanics are decent, but they are all drinking the water and have no mind of their own, and cant even stand up for themselves! Not to mention, not all are experienced or qualified as much as stated on any forum they have. read more

I had my Camaro towed to Grumpy's because I was having a no-start issue. They were able to provide towing at the cost of $100, which I later found out from the kind tow truck driver that his fee is always 50 bucks. So right there, Grumpy made $50 without moving a finger... Now on to the big issue.. Once the car was there they began with a diagnostic fee, which I completely understood. A few days later, I get a call saying that the wiring is not done correctly, and I will be charged about 8-10 hours of labor, coming out to a total of $1500. So a few days pass, i get a call that it's all done. When I arrived at the shop, I tried getting a detailed explanation of which wiring was redone and what the exact issue was that was causing the problem, the only response I got was "I turned the key over 100 times, and it started every single time. You are good to go now"...That wasn't the answer I was looking for,but hey, if it starts, I'm happy. I'm sure the 8-10 hours of labor that were put in, I was no longer going to have issues. The same day I get home I decide to grab a flashlight and start looking under the dash, in the trunk, engine bay, basically everywhere trying to see any new wiring or new connections. Just trying to see where my $1500 in labor went to, after about 30 minutes of looking everywhere I didn't see much of a difference, didn't see anything to justify so many hours of labor. A few weeks pass by, I haven't done anything to the car besides driving it on the weekends, It decides to not start again!! Luckily, I found a shop that specializes in LS swaps, so I take it there. Come to find out, The engine harness/ignition wiring is a complete hack job and my mechanic now is honestly shocked that the car even ran before. So now Im in the process of redoing the wiring and even getting a complete new engine harness installed into the car. And get this! I'm paying $1500 in labor again to get it done the RIGHT WAY. The shop that's working on my car now has been kind enough to send me pictures of the process, and there's absolutely no way Grumpys Did the same amount of work for the $1500 that I paid them. I would bet money that Grumpys more than likely just tapped in or reconnected a few wires here and there and called it good. I did not notice the 10 hours of labor that I paid for with Grumpy. Unless, of course, I'm paying 8-10 hours for an uneducated mechanic who is basically getting paid to learn and figure out an issue that he's not even trained to fix. In my opinion, if you own a hot rod or muscle car stay far away from this shop!! Attached are a few pictures of the work that's getting done now by a shop that knows how to get things done the right way. One last thing, I'm sure I could've had the car towed back to grumpy to have a second look. But now having an opinion from someone else, I'm glad I didn't do that. read more

Grumpy's Hot Rod - Transmission Repair Near Me - Yuba City, California

Everything. They did amazing work on '66 classic. Very reasonable. There in Yuba city which is the only problem. Still worth going to them.

Didn't use them but they did respond to my request on yelp and even followed back up with me. I would have used them but it didn't make sense at the time but I will someday. read more

It's such a shame I am having to write this because the owner initially seemed like a nice guy. Courtney in the office is completely unprofessional. The moment I questioned the cost of repairs (which we paid) and got a second opinion her entire demeanor changed. She started speaking to me in a disrespectful matter of fact tone, cut me off as I was speaking as if she was reprimanding me and she even called the place I got the quote from and bullied them verbally for giving me the information they did. When she called me back after bullying the other shop she even had the nerve to criticize me for getting a second opinion. Bottom line we were over charged by Grumpy's by at least $300 in comparison to the quote received from another shop. That is not competitive pricing. After speaking with the owner he is completely aware of the way business is being run just as previous reviews have stated. I do see now why they have the bad reviews that they do and also why they are currently going through a law suit with another customer for shady business practices. This was definitely shady and Unfortunately we fell victim to the Grumpy's scam too. Notice how they had somebody go on and make a positive review less than 24 hours after I posted this. Then had the audacity to send me a negative message about leaving this review . Don't let it happen to you. Choose anywhere else. read more

I've called three times to try and get some work done on my 2024 F150 and there's a few things I wanted them to do , intake manifold , cold air intake , throttle body , upgrade full exhaust system , Stage three lowering racing suspension , short tube headers , and a few other things I wanted to do as well , but the lady I talked to laughed because she and her husband that works there said I probably wanted some springs cut so they never called me back . And I've heard a lot of good things that came out of there. I just wish I would have gotten to experience it. read more

I was going to skip this review but it's only right to warn people. I brought a newer mustang in for an engine swap (I supplied engine compression tested ect). Engine went in (direct replacement) and off I went with a nice big scratch across my hood from them washing it...and a happy customer video... that very day engine started to misfire almost immediately ...was this not tested. I went back of course and asked to diagnose, after some BS "fixes" i drive off to find the issue persists. At one point they brag about having a Dyno in house so I request to the shop manager to dyno car so I don't have to keep coming back, he says he will, he does not and I pick up a misfiring car once again. Next visit I explain my frustrations with owner and he then places it on dyno and again I receive car only to have same issue. This happens near 10 time each time seeing this as a real head scratcher, mind you this whole time I'm complaining of smelling burning coolant. The final straw was being sent home once again with a misfiring car and a set of the shops pliers sitting. On my manifold ready to fall into my belt system. I was so fed up I decided to pull manifold my self and pictures show the coolant leak that was feeding into rear cylinder causing it to misfire I am not a mechanic and found this the first time I dug into it myself (this should tell you something). After cleaning/replacing gasket (which I asked shop manager to do when installing new engine) I took the car to a local shop which took 3hrs to find the root cause was coolant leaking into that cylinder, then causing cylinder wall damage..new motor toast. This shop is lazy, have no basic diagnostic skills, and will tell you one thing and do another. read more

Came in for a ton of work on my 69 f100 I was met by and enthusiastic staff who couldn't wait to help. Tony the shop manager is extremely knowledgeable and has a genuine interest in his work as well as the vehicles that enter the shop. I don't think I could have gotten a better price for all the work done anywhere else. Will be going to them for the rest of this build and any future builds. read more

This place is great! They were very helpful & professional & got the job done. No extras, just what I came in for. Definitely recommend.

I took my daughters Mercedes there. Not only was I overcharged for an oil change I was charged 65 dollars to replace two bulbs. The bulbs were put in incorrectly and blew out the tail lights they couldn't figure out the tRansmission sensor and charged me over 50 bucks more for the oil change than the Mercedes specialist. They assured me they couLd work on the car. I know the owner which is why I took it there. I wouldn't take anything there again. The secretary was clueless and had no idea what she was doing. Threw away the paperwwork I gave her never ordered the parts from the list. That should have been enough. Take your car here if you have mOney and time to throw away. read more
