Paid 3500for transmission rebuild still not right had vehicle for approximately 4 monthsread more

Man I've had one of those years where everything from paying someone to build engines / shocks /…read moreceramic coating / transmissions / sand car building has not worked out and people over promise and under delivered . So when I take a chance on a new place I always have this ready feeling and try and not over expect anything . I took them my 2006 for a trans rebuild thinking it was done and needed to be re done ..they call me up and say it's not your trans just a shifter cable and the trans is confused on pressures. I asked them please fix it and do what ever it takes . When I went to go pick it up it was such a minor fix for them they wouldn't even take my money . They could have easily got me for thousands but they didn't . Very rare when a shop or people offering a service will surprise me so I would definitely recommend this place .

I've had an ongoing issue with my car that unfortunately still hasn't been resolved after multiple…read morevisits. Most recently, I had to return the vehicle again after the same symptom came back, and it even broke down over the weekend. At this point, my car has been in the shop for about two months total. I will say, I do appreciate that they've provided me with a loaner vehicle. That has made a big difference in being able to get to work and take care of my family. However, the overall experience has been exhausting. I've already paid for two major repairs, and the issue is still not fixed. While the team has always been willing to take the car back and continue working on it, there have been instances where things were missed initially and only addressed later. I'm trying to stay hopeful that this latest visit finally resolves the problem, but it's been a long and frustrating process. At this point, I just want a reliable fix and to be done with the back-and-forth.

I trusted Martin to fix everything and make things right. Martin will do whatever it takes to make this right and have a satisfied customer. I had to have patience and it paid off! The car feels and drives like how it used too! Martin's character to makes things right is why people should come to his shop. He will help out to the best of his abilities to make the customers satisfied. Thank you Martin!!

5 Stars - TMC Auto Repair in Diamond Bar (aka the place that actually gives a damn)…read more Let me paint you a quick "before and after" picture so funny it hurts: Scene 1: Midas in Diamond Bar, 3:50 PM I roll up with a driver's window that's basically on permanent vacation (stuck halfway like it's trying to ghost me). The guy behind the counter doesn't even glance at the car. Doesn't ask a question. Just grunts, "Yeah, it's the motor." Me: "Cool, wanna pop the door panel and confirm? I'll pay for the diag, takes 10-15 minutes tops." Him: refuses to move, refuses to look, basically treats me like I'm trying to sell him oceanfront property in Arizona. I left wondering if "customer service" is now Latin for "get lost." Scene 2: TMC Auto Repair (literally two minutes away, same day) I used to go to this shop years ago when it had a different name. Now it's TMC and let me tell you -- it should be called TLC because that's exactly what they give you. Walked in frustrated and Martin greeted me like a human being who mattered. He listened to my Midas horror story, laughed with me (not at me), and said, "Let's actually look at it." One of his techs pulled the door panel in like 8 minutes and... drumroll... the motor was bad and there was a broken plastic piece in the regulator (exactly what I told Midas Guy, who apparently moonlights as a psychic but forgot to charge his crystal ball). They got the window temporarily working until the new part arrives, didn't overcharge me, and treated me like I've been their customer for a decade (because I basically have). Moral of the story: Midas Diamond Bar just lost a customer for life in under five minutes. TMC gained a customer for life in under five minutes. Martin and his crew are professional, honest, fast, and actually enjoy fixing cars instead of playing "guess the problem from the lobby." If you're anywhere near Diamond Bar/Walnut area and need work done by people who treat you like family (the good kind, not the dysfunctional Thanksgiving kind), go see these guys. 10/10, will be back the second that part shows up -- and for every oil change, brake job, and random rattle from now until my car retires. TMC, you have my undying loyalty... and my window now goes up AND down. Magic. Show less

I recently brought my Chevy in to Toy Shop Transmission to have my 4L60E looked at. Unfortunately…read more(but not surprisingly), it had completely given out and needed a full rebuild -- something I was already mentally preparing for. From the very beginning, Kendall was upfront, knowledgeable, and incredibly thorough. Before I even brought the vehicle in, he took the time to explain in detail what might be going on and what the potential repair process would look like. He also quoted me a very fair market price for the work. When the rebuild was completed, Kendall walked me through everything that was done. He upgraded the internals from aluminum components to stronger steel parts and even showed me all the broken pieces when I picked it up. That level of transparency and professionalism is rare. Now my vehicle runs incredibly smooth -- it honestly feels like a brand new car again. I couldn't be happier with the quality of the work and the overall experience. Very satisfied customer. Thanks, Kendall!

David was involved and checked the car out. I was very nervous about what was going to be found since prior to his taking the car there, I checked his oil level and it was nearly empty! I feared he destroyed the engine. The car was checked out and much to my relief it was determined to be a bad ignition coil! Very reasonable price to repair! I was overjoyed! David also made some other very useful suggestions and recommended we replace the battery, which we did. So why am I taking the time to write this? Simple. I want everyone to know it is so refreshing to find a reputable auto mechanic that will not clean you out with unnecessary repairs, that's why! I highly recommend using them. I sure will and you should too!
