Very helpful over the phone on a Sunday. Recommend a part and where to find it at a very good rate. Thanks

I am restoring a 66 Ford Mustang and took it in to have the transmission rebuilt. There aren't many shops that have the experience to rebuild old transmissions so I was happy that there was no hesitation by the owner, Mike to do the rebuild. He was very courteous and me bring it in the next morning. During the rebuild Mike found that the transmission was missing some crucial parts necessary for down shifting. He was able to find the parts and completed the rebuild by the next day. My car is driving very smoothly now and to my surprise the price was lower than I expected even with the additional parts needed. Also the warranty for the work was extremely good. Thank you Mike! read more

In my experience I have had bad service, the manager is disrespectful and arrogant.. I don't recommend that shop transmission. read more

I've been taking my cars/trucks here for some years now. Mike and his team have always been on top of all their repairs and services they have provided to me. Just recently, I took in my 1968 C10 and they made a few modifications/repairs to my transmission and now I feel like I have a new truck. What a wealth of knowledge these guys have and a great attitude. Customer for life! read more

We had a transmission failure on our class A RV. Finding a repair shop that wouldn't take six weeks to service the vehicle was a challenge. We found a shop in Azusa that completed the job in a week, including diagnostics and sending the transmission to Harrell's Transmission in Covina, where it was rebuilt and strengthened with upgraded components, and all technical service bulletins were completed. Mike and his techs there did an excellent job quickly and stood behind their work when one of the new parts failed from a manufacturing defect. Further diagnostics found an unrelated problem. Everything was repaired, and the vehicle now runs better than when it was new. Kudos to Mike and his crew at Harrell's Transmission. I would highly recommend them. read more

Mike is a old school business man Helpful nice more important did everything and more to take car of my truck... trusted him from the second I met him read more

Many years ago I had my transmission fully rebuilt on my 1989 Ranger. Was a automatic A4LD. Problematic trans, but Mike and his team were awesome and got it rebuilt with heady duty add-ons and done right. My father has also used them for his vehicles. They have been in business for a long time, they are not a bait and switch company. I'm even taking my 2500 Cummins to have the trans rebuilt and beefed up. From what I have experienced here, Mike is a stand up guy that stands by his work. Can't go wrong. read more

I brought in my 2006 Honda Pilot in to have the transmission redone. Initially I was unsure if getting it replaced was the right choice. Mike was very helpful and informative regarding my options without pushing one way or another. I decided to have the work done and it was completed as promised. A few days later a warning light came on and Mike told me to bring it in. He said it was due to a faulty part and he replaced free of charge. An added plus was that Mike even had the extremely dirty car washed and detailed! I will not hesitated to go back or recommend Harrell's Transmission. read more

I know as a business owner I hate to have to put money into a transmissions on old service vehicles. I must say Harrells made it easy and get our van back faster then he said. Very happy with the price and work for sure will be using them again in the future if needed. read more

Knowledgeable and honest. What more do you want in a shop? We've now had two cars serviced by Mike and his guys. Can't imagine going anywhere else for transmission service or repair. read more

2nd car we took this place they do a excellent job and good prices..

Back in the day, I used to own a shop that built street rods and custom cars. We used Harrell's a few times to rebuild transmissions. They always did a good job and were on-time and on-budget, not a common feature in the auto biz.... I have never used them for removal/replacement, just the rebuilding piece. read more

Mike was as always was honest about what service work I would need and completed the work in a timely manner with great results. It doesn't get any better than here!! read more

Just got my Honda Odyssey transmission rebuilt, and I am very pleased. Got it done the day after I dropped it off, and it is shifting smooth as butter! 3-year 36K warranty. It was expensive, but that is pretty standard when fixing a transmission. I definitely recommend them. read more

Mike and his guys are top notch. We had the transmission rebuilt on my GF's Tahoe and few months back and it's been running like a champ. I just had my Tacoma serviced this morning and we're both beyond happy with the quality of work these guys provide. I would highly recommend anyone and everyone to stop by and give these guys a try. We will definitely be back!!!! read more

After going to three places for a replacement price, Harrell's was not only the best price. His service was quick and honest. Stop and give him a chance to give you a price quote. I would definitely recommend their services. read more

I have done business with this shop in the past 40 years, they were alway all right, but I hadn't had anything done since'94 or so. My old suburban started givung a bad code and then locked into 2nd gear. My Grand son in law said he has a good Christian mechanic that can check it out. I wait a week to tow it in(because there was no room) and another week before I call him He says that it needs a new trans and it will be well over $3500, then he asks for a door key because he locked the drivers key in. The worker in the shop said that they couldn't get into it because they locked the door and did not even call us. I had it towed to Harrel's and they computer chip was fried, they couldn't even get a code from it. He sent it out to get fixed, fixed the starter like I asked and then serviced the trans - there was nothing wrong with it. Years ago, I worked delivering auto parts and trans shops were all sketchy, I am so glad that we have an honest shop around. BTW, the work they did in the 70s-90s was stellar, I was very happy with them. Now that I drive old cars again, he will be my go to and you can't go wrong, either. read more

Had my tranny done here 5 months ago and wanted to wait several month to see if things were still good. Things are great! They rebuilt my tranny on my 2005 cadillac cts and gave me a great price! Thanks! -nate read more

I took my 2002 Chevy Tahoe in because of a not so nice grinding noise coming from the transmission. Mike "the owner" was very polite and professional since my first phone call. He inspected my car and got back to me right away. Unfortunately it was as bad as I had feared, I would need to have my transmission rebuilt. After doing much research I found the price he quoted me as very fair, not to mention that the car was ready on time and he even took the time to show me and explain why the parts needed to be replaced. If your looking for a reputable transmission garage, definitely check them out. read more

Solid work and a very honest assessment. Reasonable price to fix my truck and a quick turnaround time. I'm very happy with the work and service. read more

Had the transmission rebuilt on my 2007 Yukon GMC. Completed it on time. Great warranty! When I got home, I noticed it was taking too long to drop into 2nd gear. Called them up, took it back, they fixed it, and it is working perfectly! Would highly recommend them to anyone looking for an honest, reasonable tranny shop! read more

Excellent customer service, quality work, and great price. I will definitely come back. These guys also give you advice on other car issues, maintenance, and they go above and beyond to make sure you and your vehicle are well taken care of! You will not be disappointed! ( as a woman I usually get employees from auto repair shops who try to talk over my questions and are dismissive to rip me off, not these guys. They explained everything to me , showed me pictures of what they were going g to replace) read more

Great communication, quality work, honors their warranty without question, bends over backwards to take care of the customer. Harrells has rebuilt the tranny on three older cars for me and my family members. I am a repeat customer and 100% satisfied. read more

M I K E is AMAZING! As soon as I called and explained what my issue was, he gave me thorough possibilities of other things that could have happened. He was able to take my car in first thing in the morning, I was even 15 minutes before the shop even opened but he gladly waved me in. Right off the bat, I could tell he was a genuine guy wanting to help the public and stands by his guarantees 100%. He let me know that he gives a discount through a rental service if need be. After a couple of hours of being in his hands, he called me to give me full detail of what happened and even shared pictures of the damage which truly helped because I know very little about cars. He was able to do a lot of work within 2 days and I couldn't thank him enough for it. Overall amazing service and an amazing guy. I will gladly bring my car back here! read more

I don't even know where to start. I gave Mike a call trying to get a quote for a new transmission. Not knowing anything about cars or what's what part. He calm my fears down and told me not to jump to conclusions; maybe I didn't need a complete over haul. I took my car in on a Monday and got a call a few hours later, unfortunately the worse scenario became a reality. My car needed major repairs. He warned me my car would need to be in the shop until Friday the latest. I came by Friday afternoon, and it was still not ready. Mike offered to pay for a rental car over the weekend, kind gesture! Monday rolled around and he found another part that needed to be repaired to complete the work he preformed. Since he didn't initially quote me for this part, he didn't charge me. Now, Tuesday, I have my car back and it drives like new! If you are looking for an honest, reputable transmission team...This is the place to go! Nice work guys... very professional, honest and hard working to satisfy their customers! read more

just had my transmission redone. i was given a quote that was almost the same as the actual price. the tech fixed a few other things while the transmission was out. the time i was given for the repairs was spot on. my 2005 honda is like new . the warranty is fantastic.. i could not have chosen a better mechanic to fix my car and the cost was more then fair for the time and parts . if you need any transmission work harrell's is a winner. read more
