They kept me updated throughout the entire process and even sent me videos showing the work they were doing. Eddie explained everything step by step and never made me feel pressured. I waited a couple of days before leaving my review because I wanted to make sure the original repair was working properly, and I'm happy to say everything they repaired turned out great. I had a separate issue with the car that I chose not to repair at that time, but because I trusted their work, I'm now returning to have them take care of that issue as well. It's difficult to find honest mechanics you can trust, and I've had an awesome experience with them. Thank you, Eddie and your brother, for your excellent service!

From the beginning, John, the owner, and his son Jonathan were honest, knowledgeable, and straightforward with me. What I appreciated most was that they took the time to properly look into the problem instead of immediately telling me I needed the most expensive repair. They explained everything in a way that was easy to understand, kept me informed throughout the process, and got my Camaro repaired and back on the road. John and Jonathan genuinely seem to care about their customers and doing the job right. After all the stress I had been dealing with trying to get my car fixed, it was a huge relief finding a transmission shop I could trust. Great customer service, honest people, and quality work. I'll definitely be coming back to El Monte Transmission for any future transmission needs. Thank you John, Jonathan, and the whole team! Highly recommend!

He explained that the transmission was having trouble shifting into third gear and would eventually need to be rebuilt. He also provided an estimate for the repair. Since the car is older, I decided not to invest additional money in rebuilding the transmission. Even though I chose not to proceed with the service, John still took the time to explain my options and recommend what I should do next. He went above and beyond, especially considering that the diagnostic was free. I truly appreciate John's honesty, helpful recommendations, and excellent customer service. I highly recommend him.

I was a bit hesitant about writing this review, but after one last phone call with Israel (manger),…read moreit feel obligated to let people know. I had a very disappointing experience with California Transmission. I came in looking to swap Chevy Astro transmission and the high selling point with California transmission would be completed in a one day turnaround. However, unfortunately, I found myself having to call the shop multiple times for an update, and we're constantly hesitant to update me. In the end up having to wait three days to get my vehicle To make matters worse, they failed to properly reconnect my oil dipstick to the engine block, which is a basic but critical oversight. I know that mistakes are common, however, granted to the fact that Israel emphasize how professional they are 25 years of experience, I am surprised something like that went unnoticed so I went ahead and give them a call today and after the vulgar conversation, he gave me I decided that I ultimately had a write a review. Overall, the lack of professionalism and attention to detail makes it hard to recommend this shop. I will provide photos below to show that I am a true customer and not a fake reviewer.

Took my rear end in for inspection before I reinforce it and get it chromed. Said everything was good. Took it to him when it was chromed picked it up and when I put fluid in it was leaking from the pinion seal right away and from the passenger side axle leaked out all the fluid over night. Took it too him he fixed it and it leaked again and blamed the hydraulic and the chrome. I then took my rear end to my mechanic and was told that it's leaking due to Isaac from Alcantars putting the wrong seals on my pinion. He also then said my rear end is not good since it's leaking from the axles after he had told me it was good. After taking it him twice he couldn't fix the leaks and Continued to blame it on the chrome even after he said he cleaned it I guess he ran out of options or excuses at that point. Wasn't going to right a review but my rear end is still leaking from the axles now. Have no idea why thinking they messed my rear end up by grinding down the housing too much which is the reason they added a life saver bearing to it which solved nothing. Also the last time I picked up my car my lug nuts were all loose on both side. The driver side lug nuts were even on backwards imagine that. Don't know how's that even possible but that's the work you get from these guys that say they can't guarantee there work Do yourself a favor and save your money, time and frustration and don't go here My loss is your gain if you follow this advice
