Horrible, do not give them money. Put a deposit of $500.00 was told if I didn't get it done I could get my money back. Came down with Cancer, homeless and now they tell me they don't know what I am talking about. read more

Had an issue come up , I thought my engine was cooked in all honesty . Next morning I call my friend and he refers me to this shop . I get in touch with the owner and he says bring it by . I do so , and sure enough let's be honest I thought my engine was cooked or other things went wrong the vehicle was puttering .. it was just the fuel pump ‍ got an honest and fair quote and warranties . Runs great again only knock is that it does seem it can get quite busy as some reviews might state but would recommend if not in a rush on job completion read more

Do not go anywhere near this place this guy is a scammer and a thief. He quoted me 4900 to replace my transmission for a new rebuilt one and said it would be 2 weeks... it's been 2 months.Every time I called him he would give me an excuse to why it wasn't ready. Then he did something super sketchy. He called me and begged if I can pay him all upfront before he gave me the car because he said that people hacked into his account and took money and that he's struggling to make ends meet. He said he would take off money from what I owe him and insisted on giving me a 3 year warrant. I simply denied and told him I don't trust him and that I needed my car already he said it would be ready Monday. I pull-up Monday and guess what it's still Not ready this time he says some guy from the dealer has to come and program the trans I waited there with him until the shop closed and still nothing. He then told me that he would personally take the car to the dealer and would update me in the morning. That same morning I called him and he said the guy from the dealer was already there programming it but now some part of the clutch is broken and he has to keep it 3 more days. At that point I had enough and told him I'm taking the car how it is. This place is not an honest place l. He is a scammer. Don't give him business read more

First off this guy is unreliable ,liar , with no back bone , he fix my truck 4 times never got it right truck had all kinds of leaks took it to him for the last time had my truck over 2 month didn't do nothing to fix the problem or keep me happy as a costumer, to anybody out there save your money look for a good repair shop this isn't you're guy hopefully i can help someone out an not waist your time , read more

This shop is definitely the most bullshit repair shop I have ever in my life dealt with. The owner was paid in full to rebuild my transmission on my car ($3100.00 and credit card fee). For over 2 months I had to deal with apologies, lies and bullshit. my vehicle was at his shop on and off for two months while all this pos did was clear code and gave car back to me stating he rebuilt the transmission. After leaving the shop in car I then went to smog shop to get car smogged. The smog shop said I have to drive car to get the car ready for smog. because the pos all he did was clear code and God only knows what. The pos even went on to say he would find someone to illegally smog the car so at least the tags were up to date. While my car was in the shop it was crazy because this pos was driving my car home after getting off work at night and when my daughter went to shop to check on the car, he had laundry and his personal item in my car as if he was using it for his personal use. There are multiple complaints that are going to be filed against this pos as well as a lawsuit. My apologies to all but DO NOT GO TO THIS BUSINESS NO MATTER WHAT UNLESS ITS A ONE DAY JOB and my suggestion is better be there to make sure your there during that time to make sure, he is working on your car. This guy apologizes so much and thinks apologies are going to fix the problem. All I am going to say is this guy tried to fuck the wrong person. If you look at previous reviews it appears this pos is known to do this to other customers. I even have video of him saying he replaced parts multiple time and they were defective. I asked for a refund, and he stated he already spent the money on bills. Again, he fucked with the wrong person. read more

I took my 65 Mustang for a valve job adjustment and Edgar did an excellent job on my car. He was professional, courteous and efficient! Overall I highly recommend this place. JORGE ALVAREZ read more

These people are fair and honest. I needed my trans checked out and they went the extra mile for me. Great service at a fair price.

I had taken my van into my mechanic and he said I needed a lot of things fixed I basically couldn't afford everything he said I needed fixed. My Husband decided we needed a second opinion. From my very first visit Edgar was extremely kind, professional and very honest. He told me a few of the items my previous mechanic said I needed fixed didn't need to be fixed this saved me thousands of dollars. Edgar put in a rebuilt engine, fan belt did both front and back backs also put in a C converter. I recommend my Daughter to Edgar. She said he was extremely fair with his prices, knowledgeable and professional! Edgar has a customer for life. Iam really greatful that I have a mechanic that I can trust to keep my vehicle safe for me and my family! Thanks for taking the time to read this long review. read more

the mistakes he had did on them he said he had worked on them , but clearly he had not touched them at all. His nephew had said Castro had not touched the car since I had left it there days at a time.I didn't trust the fact he parked cars on the street and I felt uncomfortable knowing I had just paid for a brand new paint job for my car. In the photo's below you can see clearly stored garbage in the back of the truck, and underneath was palettes this business.this is not a legitimate business nor a professional environment. His last words were take me to court and I will not pay you.don't trust them they will steal your money and treat your cars like trash cans! read more

See all

My wife and I live in Florida, we found Castro Transmission Center online for our granddaughter who lives in Fullerton, Ca., she needed a rebuilt transmission. Edgar went way out of his way to get the job done and done properly! Edgar fixed our granddaughters speedometer for "no charge" and gave her money for something to eat! Who does that, nobody! Thank you to Edgar and everyone at Castro Transmission Center, great job! read more

Took my ford escape because transmission was slipping. Edgar the owner was adamant it was the torque converter and replaced the converter. After the repair, first and second gear did the same but worse than the original issue. The owner said it was a different issue and refused to make the proper repair after a $2000 dollar bill. read more

Terrible people, took 8 months to return my car and they stole some of my car parts when they returned it. The first month i left my car there, they took my license plate and used it on a separate car to drive on a toll road. I was billed but that was voided after i explained the situation. The owner and his friend are frauds and thieves. They will only try to get ur car done if u pay them more. But this is definitely the worst shop I've ever taken my car to. All they do is experiment with your car read more

My car was due for it's 90,000 mile service. It's a collectors car, Toyota Solara convertible 2008, and I am cautious who I let work on it. My daughter, her husband and my 22 year old granddaughter recommended Edgar to me. He was knowledgeable and trustworthy so I'm glad I listened to my family and grateful to find a good and kind mechanic! His assistant was very helpful and patient with me also. 10+ read more

Thank you Castro Transmission Center!!!! You guys are the best!!! Friendly, courteous, helpful reliable, and dependable! The professionalism is second to none! Edgar knows everything a mechanic needs to know about an automobile. My Mercedes s500 wouldn't start, and right away Edgar figured it out and fixed the problem in a timely manner. Whether it's transmission problems, or just simple car issues, give Castro a call! You won't regret it! read more

Edgar has done transmission rebuilds for me on 4 vehicles I have owned, including a 700hp big block Chevelle. I've never had a failure with any transmission he has built, be it a daily driver or in a car that I raced. He is especially talented when it comes to a th400. read more

I had a transmission fault in my BMW 750i. Edgar at Castro Transmission Center accurately diagnosed my problem, provided a reasonable estimate for repairs, and then promptly made the repairs I needed. The car is now running like new. I encourage anyone having problems with a European car (e.g., Audi, BMW, Mercedes) to let Edgar take a look at it. He likes working on them and he is very good at it. read more

Castro Transmission Center - Transmission Repair Near Me - Ontario, California

I actually do all my own repairs to most my vehicles but when it's rebuilding a transmission I go to Castro! If your looking for a huge building with lots of overhead and a a/c waiting room this isn't your place. But if your looking for a solid repair on your transmission Castro's is that place. Personally, I find Edgar to be an honest straight forward person. Because I repair my own vehicles I can tell when someone is not exactly telling the truth. With Edgar you get the straight forward knowledgeable answer or he will say I don't know. I appreciate the honesty! When I got my truck back he even went to the trouble to wash the truck and vacuum out the interior for me. Being a 24/7 working person myself it was just that extra personal touch that I appreciate! My next repair will be at Castro's!!! read more

Owner was very helpful and informative. Will bring our cars here in the future. We have a new mechanic.

Came in to get my transmission repaired and had the best service. Happy with the outcome of my visit and repair. I will definitely come back. Thank you Edgar read more

This company is so amazing. They done an excellent job on my transmission and many of my family members and friends auto repairs as well. They also do complete auto care from alternator, starters, tune up, brakes, etc. No one in town can beat this company pricing. Thank you again for years of great service. Lenette Robinson read more

Took my classic car in to get driveshaft installed. Transmission lines corrected. I was told it would be done in a week. It wasn't. Every week I wouldn't give him benefit of doubt. But after 6 weeks I took my car back. He was able to I stall new transmission lines. But I believe they lost my driveshaft. I took my car back from them without the driveshaft. Now I have to spend more money at another shop to get the car running. read more

I'll get right to the point, car transmission was not responding how it should, took car in and Edgar was very friendly he even bought me tamales. Should've known, he recommended I get transmission reconstructed and a new radiator. He said "it'll be ready in a week" haha. 1st week he said he "fell ill and short a guy", "it'll be ready by Tuesday", (1st car rental) I called and he said "it just needed the new radiator and it was done". Gave him benefit of the doubt he was ill, I'll pick it up Friday he said "it'll be done". 2nd week, my truck went down and I made the mistake of towing it their (big mistake) now he had both my cars, spoke with him he said "car would be ready Saturday at 2pm", (2nd car rental) called and he said "by 7pm", called no answer twice or so. Called back Monday, Tuesday, Wednesday with no answer and no callbacks, left messages and nothing from this guy. 3rd week I was done, showed up on a Friday with 2 tow trucks, he was surprised and said my car 'would be done today by 7pm'', I said oh really that's nice, he had 2 other cars on his 2 lifts. I said I'm taking my cars I don't care the condition of them give me all my parts. His assistants did, my car was a mess, this guy is full of lies!!! don't trust this guy he comes off as a nice guy that talks a good game but is full of nothing but excuses. I made the mistake of granting him $1000 deposit. He then had me sign a paper saying he'll return it 6-15-24 which had blank information of the money everything was costing. I pulled out the original paper and told him why don't you want me to sign this one instead, he said "can I make a copy of that" really common man, This guy is full of tricks I'm telling you. Good luck to you if you decide going here! btw he never even opened the transmission itself so how was he supposed to reconstruct it? read more

I would definitely recommend. My car was leaking some red fluid and I pulled in here and Edgar checked out my car and installed my radiator super quick and didnt charge me half as much as Firestone charged my husband for the same exact thing. read more

To start with, if I had properly done my research and read the reviews about this place, I would have saved myself a lot of pain and suffering. The mechanic ( Edgar the Maniac ) who is corrupt and a liar claims to be the owner and is not. You never see the owner. I took my car to have my transmission replaced, he promised he would have it done in two days, but I did not have my car back for over 2 months! He broke my dash board and couldn't repair it claiming it was the ECU computer which he also messed with. He also destroyed my radio, destroyed my hazard lights. My dash board is still cracked and have to pay out of pocket to get it replaced. The outcome of the transmission is that it is now making noises and I have to spend money out of pocket to replace it again. After destroying my dash board I asked for my car back, he said I could not have it back because I had a contract, but because he destroyed my dash board it was a breach of contract. I had to use police and the court to force him to give my car back.This man and his equally corrupt female assistant should not be allowed to be in business. If you are skeptical about doing business talk to the people at the upholstery store in front of his corrupt business. Given the option I would give this place a negative star review. read more

Edgar is a wonderful mechanic who treats his customers like family! He is trustworthy and fair when it comes to his work and will work on your car like it is his own. I will definitely be coming back to Edgar and the Castro Transmission Center! read more

stay away from this place unless you have money to burn and a fleet of cars to spare! took our vehicle for transmission replacement, he gave us a good quote and a 2 yr warranty. that's where the good part ends. he so-called fixed the transmission but only to break down again in 3 months. we took it back for warranty work but every week we get some excuse, it's not ready, my mechanic quit, i am short staffed, etc. he did this for over 1 year. we had enough and demanded our car back and he refused to give it back. other people were there too asking for money back or their vehicles fixed or returned. had to call ontario pd for help. car transmission was in pieces and probably parts were taken out when we recovered it. reported him to the bureau of autmotive repair and took him to court - he didn't show - how typical. we can only hope that someday we recover our $3k he owes us. stay away - he's a crook, a fraud, and a bully according to other customers there they've been threatned by some of his low life associates. beware!!! how does the government allow him to stay in business? read more

I took my VW Beetle to Castro Transmission and I am extremely satisfied with the quality service they provided. My car was not accelerating properly and within a few hours, they had me back on the road- problem solved. Edgar provided ne with a box of damaged parts that were replaced and explained what was causing the problem. I appreciated this because he made sure "I KNEW" exactly what I was getting for my money. This is an honest business with very reasonable pricing. I highly recommend Castro Transmission and will definitely be returning for my future automotive needs!!! read more

Honestly was SO helpful and willing to continue the work when we still couldn't pinpoint the exact problem

Great repair & service my Ford Escape transmission. 3-places quote for replacement Edgar knew exactly how resolve the problem. Honest businessman. thank you! read more

Worst place to get stuff checked out. They tell you to come in at a certain time, you get there then the person is not there and come up with an excuse. Este lugar no sirve. ! read more

I took my 2008 Nissan Pathfinder with a transmission problem. I talk to Edgar who was very honest and professional with me. Gave me a real good estimate on the transmission rebuild. Plus gave me a warranty for the transmission rebuilt. Which most shop only give you 90 days. Edgar gave me a 24,000 miles or 24 months warranty. In my experience when someone gives a good warranty its because they do good honest work. I would differently recommend his services and will let other people know about Castro Transmission's Repair. read more
