Our family's Ford Explorer required a water pump replacement…read more I visited several local auto shops to obtain quotes and was shocked, disappointed, and discouraged at the prices I was being quoted for the work my vehicle required ($5,000-$7,500) Shame on me for not reading Yelp reviews before wasting my time visiting other auto shops. I read the many positive reviews for Hye-Tech Auto Repair and decided to visit them. Upon entering, I was greeted by John (owner) with a friendly, "Welcome, how may I help you?" I explained that my Ford Explorer needed a new water pump and a few other items that other auto shops had advised me would require repair or replacement. While John looked up a few items on the computer to provide me with a quote, he introduced me to his son, Harry, who happened to be in the office. Thirty seconds later, John provided a quote that was $3,500-$4,000 less than the other shops. I could not believe it. John explained that he makes his living and succeeds in his business through repeat customers, and he does not believe in gouging customers for every last penny. He also shared that when he retires, his son Harry will take over the business, and he wants to leave Harry with a solid foundation of loyal repeat customers. It was then that I knew I could trust John and his son Harry. John went on to explain that replacing the water pump on a Ford Explorer was a 10-12 hour job, as it was an internal pump requiring numerous engine parts to be removed to reach it. This was the same thing all the other shops advised me. John suggested that I leave my vehicle, and he would perform a full inspection of the engine and contact me before doing anything to it. I agreed and left my vehicle. The following day, I was contacted by John, who advised me that the water pump did indeed need to be replaced, as it was the source of the constant leaks of the water coolant. I left my vehicle in John's shop for three days. During this time, John or his son, Harry, contacted me numerous times to keep me updated on the progress of my vehicle and also to point out that mechanics had discovered two or three very inexpensive items (under $50.00) which they recommended replacing, which I agreed to have done. All in all, I was and am extremely impressed and satisfied with everything about this shop. I spent much less money to have five different issues repaired on my vehicle at Hye-Tech than what I was quoted to replace my water pump alone by every single shop I visited prior to coming to Hye-Tech. John and Harry are very friendly, honest, and trustworthy. They are also very knowledgeable and experienced, and they offer GREAT customer service and communication. This is my new go-to shop for any issues involving our family vehicles. Thank you, Hye-Tech Auto Repair, for a very positive experience.

I opened a Yelp project to try to get my transmission serviced. The dealership wanted to charge me…read more$1300 for this service. Yelp projects are one of the best things I've ever experienced. It's nice to see you can get quotes at the touch of a button on your phone. This morning, I had time off, so I headed in to get my service done. I did not have an appointment and that did not seem to matter. I arrived first thing in the morning at 8 AM and ask if the service could be done. Harry was an exceptional young man, he took me in with no problems, no questions. He said they could do it this morning. I told him I would have to wait. He had no problem with that either. Prior to bring in the car in this morning, as I said, I used a yelp project and had several people reach out and give me quotes. After looking at all the yelp reviews I decided to give this place a try. I am super happy that I did. This place is a hidden gem, excellence, service, quality, and value for what you receive. There are not very many shops where you could feel comfortable and put your trust in them. As I spent time in the lobby, I was able to see customer service on the phone and customer service entering the facility. Every customer that walked in, seem satisfied and was treated with dignity and respect. I highly recommend this place if you have any automotive questions whatsoever.

John & his team are professional, and very honest, & took the time to explain exactly what was going on with my Jeep's transmission. The repair was done by the exact day they promised, & my beloved Jeep is running smoother than ever (it's 23 years old btw) Pricing was extremely fair & I loved their solid workmanship, you can tell they take pride in what they do. I'll definitely recommend them to anyone and everyone who needs transmission work! Thank you guys!!!

I brought my 2013 Nissan Versa in for a second opinion because the dealership (where I thought my…read morenew transmission was under warranty) quoted $10,000 to replace the transmission AGAIN and replace a few other parts. Lee and Sam took the vehicle for a few hours and got it running again for a fraction of the price. They determined that the issue was not related to the transmission. Their willingness to listen, inspect, and be transparent was most striking. I'll definitely be back.

This place has really changed. I don't know if they care about selling cars more than the customer…read moreservice they used to offer, but this placed has gone downhill. I dropped my car off here because it stalled on fwy. They offered to charge me around $360 to fix the issue. Then issue after issue came up they taxed a bunch of labor, and additional charges ome which took them 45 minutes to fix. As i was on my way back from work after being left at the shop for 2 days, they said it would be ready Saturday. I made it back home in 45 minutes and the repair was done. It went from $360 to $400-500, jumped an additional $300. They charge a "non cash charge" of $32.37 on top of all that. I would have left alone and called myself a sucker. But, my Bluetooth cell phone charger was also missing. I go there to pick it up and the owner tells me only him and one other mechanic worked on the car and that guy steals nothing. Surely enough it's the same mechanic who tried to upscale patching my tire at $25 when he charged my gf $12 (in front of me btw) and i told him you charged my gf $12, why $25 now? I ended up going to get patch kit for less than $10. They even crossed out $140 per hour for diagnostic charge and put $185. ‍I didn't know on top of all the misc. Charges, fees and labor costs that i would have to take inventory of the items in your car on top of all that. Go to an honest mechanic. This will be the last time i ever use their services. Stolen goods much? No thanks. After everything i have to go buy another bluetooth charger now. Because they don't know how it ended up stolen.

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!

Second was a 2002 Yukon Denali, needed a transfer case rebuild. Just recently my wife's Dodge Durango had been giving us problems. Turns out it wasn't the transmission, but the TCM solenoid. With Angel's honesty, attention to detail, and great work ethic, I've had all repairs done correctly, with minimal downtime, and not being ripped off. He explained all issues so a non-mechanic as myself can understand. Thanks again Angel!

This is basically the 2nd worst thing that could happen to a vehicle IMO The job did take time but I made it work with getting around. Angel and his team did have to do some trouble shooting because this specific transmission requires the valve body to be primed on the bench prior to installation. He rebuilt the entire core and also changed out the engine rear main seal. Now, the transmission feels better than ever. I had to give him a little bit of a hard time about not having Zelle which he ended up getting after. Overall I would say, he really does care about taking care of his customers and will make sure the job is done correctly.

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
