    $800 of overpriced parts and worthless repairs

    Like most people, it's not like me to leave a one star review. Now, I know the economy is in bad shape and businesses are having tough times, but Johnny's thoroughly ripped me off on my repair, and just have to give a little warning if you are planning to take your car here. Although I don't want to hurt any business, I have to say that I brought my car to this spot to get my car fixed, and while they did do some work, the work they did, did not last, and I was also overcharged. I had a 420 (and believe me the price to fix was high) and 430 error which is due to either a faulty catalytic converter or o2 sensor. To avoid replacing my costly catalytic converters (my car has 4), we replaced the o2 sensors first. I was charged over $800 for everything. In a matter of a couple months, the lights came back on. Sure, it might be something else. Now, I didn't mind paying the $800 if it were fixed, however, I overpaid for my o2 sensors, which did not last for even 2 months as the o2 sensor errors came right back on. And how do I know I overpaid? Well, I paid $800 just to replace the o2 sensors at Johnny's, while that's exactly the same price I paid to completely replace both catalytic converters at another muffler shop! The other muffler shop also repaired my o2 sensors, charging me $100 per o2 sensor, where at Johnny's, I paid double (for the back) to QUADRUPLE (for the front) the price vs what I paid at the other muffler shop! What more is that I was told that my o2 sensors would be replaced with factory ones, where after looking today were denso (non-factory) o2 sensors. The dishonesty comes in where I was told that I would be getting factory o2 sensors, where I got the cheaper generic ones, but still paid full price and some for factory ones! Before coming here, there are better, more honest and reliable shops. Attached is my receipt to show what Johnny's charged me.

    Jose pulled out the computer and diagnosed my car on the spot, which I've never had a mechanic allow me to witness.

    Problem while on freeway driving: Acura TL 2006…read more Transmission changed to lower gear suddenly, then back to normal Happened twice Transmission dashboard indicator for 'D" drive light briefly brinkling I was refered by a friend who is a mechanic to this place John the owner is very helpful He used his computer tool to check any error code Then he test drive the car, but could not find any problem I feel bad for him, he spent almost and hour, and I wanted to give a some money for his time He refused, his shop promises free diagostic I asked for his business card and assure him I will bring my car there if I have any transmission problem in the future This change to lower gear problem I have had in the past only when driving steep downhill - from 4th or 5th down 3rd gear, then back to 4th or 5th again I hope this car will last a few more months I strongly recommend you to visit his store if you have a tranny problem

They took a look at my car for free to identify the issue and they detected the leak to be coming from my engine and not my transmission. They showed me exactly what they were seeing, why they thought it was my engine and not my transmission, and offered to put a dye in my transmission fluid to ensure it was my engine and not my transmission. I drove my car for a week and took it back to double check, and sure enough it was my engine! Although they spent time and care on my car, they didn't charge me a single penny, even when I insisted to at least pay for the dye. They were able to refer me another mechanic to fix my engine leak and I was able to get my issue solved that same day. As a woman who is nervous to get work done on my car, I had an excellent time at El Monte Transmission. If you are having transmission troubles, please go to them :)

I found Francis through an online search because of the many positive reviews, and during our first interaction he was friendly, professional, and seemed very knowledgeable. He ordered the part directly from Acura and quoted me a fair price. My car was ready the following day, but when I arrived to pick it up, Francis informed me that my vehicle had been involved in an accident while in his care. He explained that another driver had been speeding through the parking lot and crashed into him. He gave me the other driver's information, and I contacted him immediately. The other driver gave a very different version of events. He stated that he was backing out of a parking space and did not see Francis. He also told me that Francis provided his driver's license information but refused to share insurance information. Now, more than a month later, I still have a damaged vehicle and have not received insurance information from Francis despite multiple phone calls, text messages, and outreach from Mercury Insurance. I trusted this shop to take care of my car, not return it to me in worse condition and leave me responsible for a $500 deductible. What has been most disappointing is the lack of accountability and urgency. Francis acted as though this situation was not a major concern and repeatedly assured me that the other driver would "take care of it," which has not happened. According to the other driver, Francis even asked him to change the story about what happened. I chose this business because of its strong reviews and the image Francis presents, but my experience has been extremely stressful and disappointing. I believe customers deserve honesty, transparency, and responsibility when their vehicle is in someone else's care.
