We did a family vacay to Legoland last weekend and somehow ended up in Burbank the day we were supposed to go home (last Sunday). We decided to eat at In n Out before heading home and thank God we did because my check engine light came on as soon as I entered the parking lot. Went to O'Reilly so they could scan it and give me a code. Turned out to be my transmission. While standing outside of O'Reilly trying to figure out what to do a random customer came up to us and referred us to Leon's. He said he just got transmission work done recently and he highly recommended this place. They're closed Sundays so we stayed another night and took it the next day. I had to leave my car in California because it was too risky driving it back to Vegas with transmission issues but they got all the work done by Weds. I drove back to Glendale Friday to pick it and made it back to Vegas just fine! Thank you Steve & Roxy for all your help! read more

If I could give Leon's Transmission more than 5 stars I absolutely would! I had what I thought was a transmission leak and Julio was able to get me in the next morning to check it out.

Highly recommend them and will be returning if I have any other car problems! read more

Super honest and excellent work. Julio really helped me out. I highly recommend them. It's nice to find that neighborhood feel in LA.

I was told by an oil change shop that I had a transmission issue, so I brought my car to Leon's to fix it. They inspected it for free, confirmed there was no transmission problem, and even pointed out what the real issue was--without trying to upsell or push unnecessary repairs. Honest, helpful, and professional. Highly recommend! read more

Always worried to take my car to a mechanic and arrive assuming forthcoming bad and expensive news especially transmission news, which is so expensive. This was a different experience. Leon's Transmissions is 100 percent HONEST and oh my gosh, what a relief to meet such good people. Julio is awesome and I so appreciate the service .Will be back ( hopefully not soon) and wholeheartedly recommend . Very honest and absolutely not out to get you ,especially if you do not know a lot about cars. Thank you guys very much! read more

I was referred here by another mechanic to replace motor mounts and a rear main seal, because of an oil leak, on a 2007 GMC pickup truck. I already had the motor mounts that I purchased directly from the GMC dealership. Bad news for me, I did not know that they do not allow customers to bring the parts themselves. So I had to have that service done elsewhere. They replaced the rear main seal, and they also serviced the transmission. I felt they were fair in price. I wish they could have put the mounts in because I still have problems with the clunking sound when you shift out of Park. I will go there again as needed and recommend them for full sized pickups that are too much vehicle for some mechanic shops. read more

I need some work done on my 2008 Toyota Tundra transmission Jose from Pep Boy's recommended Leon's Transmission Julio was my point of contact and was very thorough about the cost and work to be done on my truck. The work was completed soon than expected and the price was lower than estimated. I was very happy with Julio's service and the work done on my truck I driven the truck for awhile now and the transmission is working fine I would highly recommend this business for any customer needing transmission work read more

Excellent service, honest policy and manager. Had my transmission replaced in January 2024. Vehicle ran well, went in for the 12,000 mile check-up. Shortly thereafter a part went bad. Chris, the manager, honored the warranty without hesitation and fixed the issue. Vehicle is running well again! read more

Leons will check out your car for free if you can leave it for a day or two. If they can not determine the problem from external observation or scan tool then they will call & ask permission to 'drop the transmission pan'. You pay $160 for this - which seems reasonable. BUT - what they don't tell you up front is it will be VERY rare to find a part that's simple or easy/accessible to replace on any transmission from just dropping the pan. If they do see a broken part or vague 'metal shavings' (all transmissions create 'metal shavings' & pans have built in magnets to catch them) and you tell them to "fix it" they tell you they have a policy of generally not replacing one or two obvious broken parts BECAUSE they can't guarantee the fix so you need to let them 'rebuild' your trans. So 'dropping your pan' is just a useless ruse to lock you into letting them 'rebuild' the transmission. All this made me very uncomfortable so I asked them to replace pan & fluid (covered under $160) so I could take my vehicle. This was the late morning after leaving vehicle with them for a day & a half. They were surprised I asked to take my vehicle and started trying to sell me on two levels of 'rebuilding' i.e. 'performance' or 'standard'. When I responded "I want my vehicle back" they told me they couldn't do the until the next morning. By the way - when I pressed and told them them that I didn't care about any guarantee and to just replace any broken parts they still refused and said while replacing the parts could 'possibly' work they wouldn't do it because their policy prohibits them. So I asked - "if you knew that you don't replace 'parts' what was the point of dropping the pan?!" - they just stood their fumbling their words. I asked what I would get in the way of work & parts in their 'rebuilt' transmission their answer was "it's too long a list of parts to tell me or print out". They also said that they will need vehicle for 2 weeks minimum while my trans was sent to their Gardena store to be rebuilt (I strongly suggest reading the 'few' bad reviews of this other location). If you have read this far you're now going to learn some very important information: Google "re-built" transmissions to see what mechanics think of them. Their consensus is if they last a year & a half you are lucky & that most trans shops have a similar pattern and technique to arrive at the same conclusion -"Let us 'rebuild' your transmission" after they drop the pan. DON'T DO IT. DON'T FALL FOR IT. *Secret: 'Re-built' transmissions are NOT the same thing as 'Re-MANUFACTURED' transmissions. Sketchy rebuilds only offer 90 days to 2 years depending on how much of a gamble they want to take. But a 're-manufactured' transmission is a whole other ball game giving you a 3 year UNLIMITED milage guarantee state to state nationwide. The remanufacturer actually backs up their warrantee (parts & labor because most of their biz is through mechanics so they have a vested interest in repeat biz). Where ever it breaks down they will pay a local shop to repair. Look at Jasper & ATK for a few (factory videos online). They only remanufacture they don't install and with Jasper it's all done in the USA at a state of the art facility with testing. I called back to Leon's Transmission to ask if they could just order a remanufactured one and install it instead of 'rebuilding' mine - I practically begged & said I would understand any up-charge - and they said "no way". I guess their profit must be pretty serious on their 're-builds' (hmmm). You do pay a bit more for a 're-manufactured' transmisson but the longevity is there because almost everything is replaced and testing is done in a huge clean factory with standards & machining facilities rather than the back room by who knows who. Most every mechanic and trans shop are able to order direct at discount from a 'remanufacturer'. And not only does your new re-manufactured transmission come ready to pop in with torque converter included (dyno tested too) - all the shops I called said it only takes 1 to 2 days max to install. Compare that with the 2 weeks or more for Leons to 're-build' mine. btw - Leon's was 3200 for their basic rebuild (more for their 'performance' re-build). I got a quote for a re-manufactured installed elsewhere for 3800 out the door. So I brought my vehicle to the other place to make sure their quote was correct, the guy test drives my vehicle & says he can do it for price quoted but that in his opinion he didn't think the slippage in my existing trans was all that bad and that if it were his vehicle he wouldn't worry about it and to just keep driving it as is (!). When we arrive back at his shop from the test drive he checks the fluid level (remember Leon's had to refill it) and he found it about 5 quarts too high (?!). I called back to Leon's furious as too much fluid can damage your transmission and they said "well, we, uh, just put back in what we took out". Yeah, right. read more

I am so grateful to have been referred to Leon's Transmission Services. Ben and Angelica were amazing. It's never easy to hear the news that your car needs major work done but I can tell you that it made it much easier because they were professional, friendly and very kind to me. They were also great with following up with answers when I called with questions. Thank you again very much! My car runs like it did brand new! I highly recommend Leon's for transmission services! read more

My car needed help with the transmission and Ben and his team helped me out with a quick turnaround! They were honest about the price and the labor cost. Ben broke down the issues with my vehicle and the repair process was very smooth. When I got my vehicle back, it drove so much more smoothly than when I brought it in. I am very grateful for this place and glad the issue was resolved!! I will be back if need be. Definitely go here if your car is older or has discontinued parts as they are able to help more unique situations. read more

From the moment I brought in my car due to a transmission issue they were updating me about the issue. They were prompt to identify the issue, provide cost, and repair time. read more

I brought my 2010 FJ Cruiser with 6-speed manual transmission to Leon's due to bad 3rd gear synchros. Gerard and his team at Leon's were excellent. Incredibly knowledgeable, very easy to work with. I always got the feeling that they went above and beyond to help out. I did have some minor communications issues; phone tags and the like. But I think that's more due to Covid than anything else. I would highly suggest Leon's to anyone looking to get their transmission repaired. read more

I came here in 2020 to fix my mini. He replaced the transmission and it worked for about a month then the car started acting up the same way it did when I first brought it in. Spent almost 3k on it to only have it break down again. read more

Updating my review because not even 2 years later the same part has gone bad again... I've taken my car to another mechanic and he can't 100% confirm the TCM board was used but with his experience it should have lasted me 8-10 years and he pretty confident it was a used TCM board. I paid the price of a brand new and got a used one & a few weeks after the repairs from Leon I had a lot of rattling and loud shaking noise start. I didn't take it back because I've moved from the area and even if I hadn't I felt like maybe they weren't as great as I thought. Since finding a new trust worth mechanic I Definitely feel like i was taken advantage of read more

I had great service and realistic repair times. I didn't realize that transmissions are so specialized, and complicated, and due to supply chain problems a wait for parts. The Leon's Glendale is close to my residence in Silverlake and was recommended to me by my friend who had his truck transmission done at the Leon's in Reseda (there are 8 other locations). When the work was done they gave me a 2-year warranty. Angelica the front office manager, and Ben the service manager were very friendly and approachable. Ben cautioned me to not miss the transmission flush and service they require after 10K miles of driving to remove any metal shavings from the new gears seating in to maintain the warranty. I will definitely recommend them to others. Rick Feldman read more

Went in for a transmission rebuild; paid $3999.45, AND IT WAS FAULTY. Literally, the day I picked up the car, it was JUMPING in idle and while stopped on the freeway and then the ENGINE light comes on. Their recourse? Take it to someone else to check the engine. We fixed the transmission: "It's the luck of the draw." Seriously? I've never gotten my car back after a major repair and no one test drove it to check their work because I FELT IT UPON LEAVING. Now I'm supposed to trust that the work was done correctly...this time. And pay someone else for the engine that was fine before we took the car in. AWFUL. ZERO STARS IF I COULD. read more

Waited for me on a Friday afternoon, when I called in at 15 minutes to closing when I was stranded with a transmission emergency! Great customer service, great price, even fine tuned their work later when it needed adjustments. They earned a customer for life! Thank you LEON' S!! Big shout out to manager, BEN! read more

Leon helped me with my car cause it was leaking oil ! Fixed the problem in half a day will go back

John was incredibly helpful! I called a general mechanic for what I thought was a transmission fluid leak. The mechanic referred me to Leon's Transmissions. They did a complete and thorough inspection in the time frame they told me it would take. It turns out, I didn't have a transmission fluid leak, but they were able to spot the actual problem (nothing to do with the transmission) and explained it to me so I know what to tell the general mechanic. They were very trusting and honest from the beginning. I even took a second car with them! Thanks Team! read more

The manager was beyond rude. Not only could any Tech not figure out why my car had no drive or reverse, I got a call a day after Christmas to come get my car or there would be a storage fee. I will bring my car to a shop that has a clue on how to fix a transmission. I live 70 miles away from leon's and was planning to take the train back down to Glendale to pick up my car but the trains were not running due to Maintenance on the track. All I got back was I had to pick up my car that they didn't have the knowledge to fix but I better do it soon or I will be charged a storage fee. Way to show the crappiest customer service I have had to deal with for awhile and that's saying something nowadays. If you want your cars transmission fixed don't go there! read more

Very hurtful review - deception, dishonesty and lies... For 14 weeks I rented a car via Lyft for $230/week plus the required 20 rides a week. I also worked overnight in a residential concierge position FT, and I am a single mom of an emerging and busy performing artist. EXHAUSTING. Why do I tell you this? My 2013 Dodge Dart, which I was committed to repairing, after an over $3K high rate loan borrow and transmission replacement/repair at Aamco in Burbank (it) would not run, they said due to an oil leak (and claimed it ran fine after they cleaned up the spill, but that's a lie) but Gerard at Leon's said that it was because the new-to-me transmission that Aamco recently put in had a bad hydraulic pump on it. He even did a little teaching on the human heart and asked me what does the heart do...and further explained that that's what the pump does. Gerard further advised me that if I were his mother or sister that he would suggest that they not place another penny in that car. And that although it may be tough, to turn it in to the bank. TRUST ME He gained my trust because I was referred to him by my general mechanic and he tested the car for over a week and was very communicative, he kept me informed at every step. The conversations and professional recommendations seemed honest and sensible for the money I had already spent with Aamco (who would not honor the 90-day warranty, after the 90 days) and the fact that Gerard told me that I should return the car to the bank. Gerard further advised me to voluntarily turn the car back in to the lien holder and that he would conduct a lien sale and take the car off of my hands via auction, etc. SPILLING THE TEA After posting my review about Aamco, the owner Neil Evans reached out to me, via Yelp direct email and told me that he spoke to Gerard, and that Gerard told Mr. Evans that I just abandoned and/or gave up my car; and that he sent my car to another Leon's Transmission Services, where they have a general mechanic (which Gerard never shared with me) and that the general mechanic fixed the oil leak and they are now using my former car as a shop car to run errands. WHAT HAD HAPPENED WAS... Gerard even spoke with my former lien holder and explained to them what was wrong with the car. According to him, they told him they didn't want the car; and that they [supposedly] said that they didn't know who the lien holder was. Since they never returned my calls and they actually called him, I believed it. Per Gerard's advice, I brought him the unsigned title so he could conduct the lien sale and I even received a note from DMV. Gerard told me that they had to go through with the lien sale now that the DMV was involved. He looked over my new used car, to make sure it was a good car; I cleaned out my old car and went on my way sad, for the major credit hits, but ready to start anew. BACK TO NEIL SPILLING THE TEA VIA EMAIL I was completely gobsmacked, when I read his email last night, tears just rolled down my face because Gerard informed me that the hydraulic pump on the transmission was bad - yes he said the oil was leaking but that was not why the car would not run. Honesty, respect and loyalty are very important values to me and although Gerard evaluates my car for nearly two weeks, he knew that I would follow his advice and he knew what his ulterior motive was. When Mr. Evans reaches out to him this week, he told him a completely different story than the professional advice that he pretended he would even give his mother or sister. When the DMV recently sent me a letter of pending suspension for the Dodge I called them and told them of the lien sale, of which they had no record. Once I was out of the picture, Gerard put his real plan in place. My car was very fixable, so fixable that they are using it now at another location for free. I unwittingly gave Leon's Transmission Service my car and they get to drive it Scott Free. Gerard deserves an Academy Award for best actor - seriously. He seems so sincere and helpful but please know he's got hustle all in his blood. Hurt, but still I rise. read more

Best place in town for trans repairs. Look for Gerard, very honest and knowledge guy. Wish it was more technicians like him in the city. BMW trans oil service done and very satisfied. read more

i wouldn't consider this repair shop at all you stay far away - don't leave disappointed, Leon is a person but this business is so sub-par, such attitude, such haughtiness, outrageous, this particular location is a not so known for being there a long time it's newly established and this Ben Lopez holy cow dont waste your time, the people there discriminate against different minorities and races - don't give this business a dime of your money - trust me when I tell you You will never feel satisfied going to a place that's acts so distrustful, the staff walks in their office with no uniforms low class shuffling w/their boxed lunch - their just there to see punch the clock - not even the class to know how to greet anyone You might know the man in the radio but the people left to represent his business are nothing but the nastiest read more

Great service from Gerard at Leon's transmission (Glendale). He will give you honest advice. They replaced my transmission fluid, and respective filter. They were highly recommended from one of my mechanics. read more

Free diagnostic was cool. Throughly checked my car and gave me piece of mind. I'll be back next time my car needs a check up.

Leon's has been my go to for transmission repair for the last 15 years. The guys at the Reseda and Glendale locations have been some of the most professional individuals I have ever dealt with in the automotive industry. Ask for Gerard at the Glendale location or Mark at the Reseda location. These guys know transmissions. If your transmission is acting up, give the guys at Leon's a call. You wont regret it! read more

My car was broken and my transmission was shot. These guys took a look and gave me a diagnosis without charging me.

This place is amazing, especially Gerard. A really great, down to earth mechanic, and knowledgeable. He ran diagnostics on all systems even though I only expected one. He explained what was going on inside my transmission. He helped me discuss where to go from here, what my options were, what's cheapest, and what's going to be fair. I was seen immediately by the friendly desk clerk. The experience was quick, warm, and welcoming. I found my new go-to. read more
