Here are some of our favorite testimonials:

Had to bring my 2010 Accord in here yesterday for transmission work. Just showed up without an appointment since Jiffy Lube refused to work on my car for some reason. Leon's was willing to check it out, gave me a quote, opened up the transmission and found that a squirrel or something had chewed through some wires. They told me an hour and half and got it fixed in about 40 minutes. Car drives great, and there was a yelp coupon they let me use. Bring your transmission issues in here instead of a dealership or a lame place like Jiffy Lube.

I have never been more surprised by the genuine honesty and treatment from a car mechanic. I was experiencing transmission issues and the gentleman at Leon's treated my car and fixed a simple issue without overcharging me or exaggerating the issue and making me pay for it. If you want good honest work by people who just want to be known for treating their customers like family....this is the place.

2009 Honda Fit w/check engine light & blinking "D" on the gear indicator panel, multiple codes. Leon's quickly diagnosed it as an electrical problem, and gave me a reasonable "not to exceed" quote on running down the electrical problem (didn't know if there were other problems underlying -- turned out there were not). Prompt, professional service -- fair price, work performed as quoted.  The car is back to running perfectly. Problem appears to have been rodents chewing on the wires.

I had to take my car in there this week. They explained everything to to me in simple enough terms and explained why they needed to do what and why.  Despite the lengthy repair time, 2 days, they worked hard to make sure I got my car as fast as possible.  Leon's Transmissions is a place I would recommend to anyone if you need your transmission worked on.

When my transmission failed, I had no idea what to do. I was referred to this shop and I am very satisfied with the repairs they performed to my vehicle. The manager explained what repairs were needed. The repairs were completed faster than I expected.  I have now been driving my vehicle for a few months and could not be happier. Great Service!!

I originally took my Ranger here about 6 months back because I had some transmission issues. My dad swore by Leon's and said he wouldn't go anywhere else for transmission problems. They were really quick about fixing it and getting it back to me.

I recommend this place to EVERYONE who needs transmission work! My family and I were getting ready to leave to Lake Mead for Memorial weekend, and they got the job done in less than a day. Their prices are reasonable, plus It comes with a GREAT warranty, so no matter where you are in the country, you're covered. Thanks Leons!

Was referred to them by AAA, and they did my Honda transmission. 4 years later, still running smooth and perfect. Nice front desk people, fast professional service. I am on my way to pick up my truck, which only turned out to have a small leak. Charge was around $143.79. Which means they are honest too. Don't hesitate!

Great customer service! I had my car towed in after it broke down at the intersection of PCH and Balboa. I thought it was the transmission because I heard a clunk and afterwards the car wouldn't move forward or backwards. They immediately put it on the rack and discover it was the axle which was under warranty at another garage. After calling for a tow for the second time I asked if there was a diagnostic charge and was told no. A great surprise. I'll be back when I really am in need of transmission service.

This is to commend your wonderful service to me when my car was brought to you from Mountain View Tire & Service earlier this month. I was from out of the area when the car broke down and had to do business over the phone to get it fixed. You were very cordial and patient in explaining to me that the problem just seemed to be the shifter. Since the transmission and clutch were still under warranty, you did all this free of charge which I really appreciate!

I would like to express my and my family’s appreciation for the wonderful service that you provided. Late on Sunday, March 25, 2012 we were on our way to San Diego when our car broke down, the manager at PEPBOYS recommended Leon’s Transmission to diagnose and repair the problem. We want you to know how grateful we are for the wonderful service that you and your crew provided. We were kept undated on the progress and the cost of the transmission repair. The car was repaired and we were able to come home on the day that we planned to return home. Please extend our deepest appreciation to the staff that was involved in repairing the car and making the calls to keep us updated on the progress.

My son Jonah recently returned from his first deployment and shared stories about the positive impact of our care packages on the morale of his men, which made me think of Leon’s Transmission’s support over the years. Not just as the founder of Operation Gratitude but also as a Marine mom, I am forever grateful to you for Leon’s Transmission’s generosity over the years that have enabled us to send 800,000+ of these care packages. My deepest personal thanks for your kindness.

I needed a new transmission for my 2017 Suburban. The price they gave me was very fair and much lower than the dealer estimate. They completed the job on time and when I needed a major adjustment (not their fault) they did it with a smile and when it was convenient for me. There was no extra charge and now my truck runs better than new. I highly recommend this business and how expert and professional they are.

I brought my Rav4 to you to check my transmission. You gave me the Technical Bulletin #1026 stating that my power-train control module was under warranty for 8 years or 80,000 miles. I called Toyota Consumer Affairs. After long patient discussions, they replaced the computer.

I’m writing to thank you. I’m living on a disability fixed income. It was very considerate of you to give me the information. I really appreciate your kindness.

We are new fans! My husband's car had some transmission sounds and when we took it to the Lexus dealer it was $8600 and needed to be replaced. Leon's said the sound was something to be worked with and that the transmission still had a lot of miles left it. It was a $200 fix. These guys are super ethical and I can't say enough good stuff about them. Thank you so much there is a business out there that is honorable in this arena.
