He did not automatically assume the transmission would need to be rebuilt, he looked at all the options. We called several other transmission shops for assistance and service, they ALL automatically said we would need to rebuild the transmission and ALL were more expensive than Transmission Doctor. He called many times throughout the process to keep us informed of the status. We are very happy with the work he did. I would gladly take any vehicle we own to him, and confidently send anyone to him as well. Additional note - He just called me (2 days after we picked up the truck) to make sure we were happy with the work and that everything was good. I am so impressed with his level of customer service.

This place of business shouldn't even have a one star rating. I just called with questions and got…read morethe worst treatment from the manager John. To recap, I'm a parent in Houston TX with a student in Arlington TX. My son's vehicle is having transmission trouble that had already been diagnosed by the dealership. Of course, the price quoted at the dealership was excessive as most dealerships prefer to replace rather than repair. The manager john obviously hates his job and cares even less for potential customers. My call went something like this; Hi I would like to get a price range on a transmission replacement for a 2012 nissan versa. I understand you cant give me anything spec..... He interrupts with you gotta bring it in. I begin again, I understand that you can't give me anything specific without first looking at the car but i'm only looking for..... He interrupts with, I can't tell you anything without looking at the car. I don't know what it needs. I begin again, trying to explain that I'm concerned with whether the vehicle will make it in and that since repair is the most expensive service; if he could give me a part and labor cost for the vehicle type it would be helpful since a transmission repair or even rebuild would be south of that cost; but he interrupts me with, I'd need the VIN. I respond with I have the VIN. I proceed by saying, Sir if you could just let me finish I can explain what i'm asking. He snaps, I can't help you!! So I say thank you and goodbye. I call again as i'm assuming this piss poor service must be someone without any concern for the bottom line of the business, right?? Wrong! When I call back, he answers. I say, Hi John, is there someone else that I can speak to. He responds, I'm the manager here so if you can't talk to me you cant talk to anyone and I don't even want to deal with you now. I say, sir if you would let me finish.... he finishes with, take your car somewhere else and hangs up. Please don't misunderstand my position. I am well aware that total costs for car maintenance can't be quoted BUT labor and parts can be. He is simply inept as a manager and I am happy to take my business elsewhere I just hope someone in real need doesn't run into such a sad representative in the future. Lastly, this is a message to the owner, this person, John, is intentionally sabotaging your business, because there was no reason for him to turn your business and profit away based on not liking the question I asked.

Tommy just came through for us again. My son Eric was driving the old Tahoe and started noticing a coolant leak. He diagnosed it as a water pump and we gave Eric the number for Quantum. Tommy took it in, diagnosed it as a shot water pump and gave me a quote with options for replacing with an original Chevy part or a less expensive aftermarket that he knew to be reliable. Frankly, the quote was hundreds less than I expected. I am a fairly decent mechanic and would gladly pay his quoted price. He got the work done the day he was able to diagnose the problem. On time, exactly as quoted and functioning perfectly. I have recommended Quantum to friends for a decade and they all agree that you get honest work done right at a fair price. Everything you need in a mechanic shop!

If you're looking for an honest mechanic who knows what he's doing, look no further. Took my 2006…read moreMonte Carlo SS to the local Arlington Chevrolet dealership figuring since my car is a Chevy, they'd know the most about it. Engine wasn't starting immediately after turning the key. They performed their analysis and recommended a new starter and battery cables, for which they wanted to charge me $1,400+. I previously had the MC there for the same problem and, after $400+ in analysis charges, it was a $20 gas cap. Wanting a second opinion, I scheduled an appointment with Quantum. Due to their high volume of work, I had to wait 2-1/2 weeks, but the wait was well worth it. Tommy, the owner, looked at the battery cables and starter and said there was no problem with them. However, apparently some General Motors vehicles have this starting problem. Not enough fuel is getting to the fuel injectors when the key is turned. He pressure-checked the fuel pump and found it to be the problem. Rather than spending $1,200+, he showed me how to ensure the injectors have enough fuel so the engine will start on the first turn of the key. I've had cars serviced over 50+ years and Tommy is the first mechanic that took his time to fully explain the issue and the solution. He knows what he's doing and most importantly, he's honest. You can't go wrong with Quantum Mechanix.
