Great guys. Went out of their way to accommodate my schedule, super friendly, completely upfront about what needs to be done and what it will involve. One of the few places I’m comfortable trusting.

I went with Sun Valley transmission to rebuild my transmission. The transmission failed while it was still under warranty. Sun Valley transmission didn't want to honor their warranty but said if I paid for parts, they would redo the job, so I agreed. Fast forward two years, and I am again with a dysfunctional transmission. I showed up at their shop to see if they would look at it, and I was told that it would be three weeks before they could take a look. You would think I would get some consideration because I am an existing customer. When the first rebuilt transmission failed, I noticed that the dipstick had broken and it was half-arce welded by what must have been a 12 YO. The weld was very bad and didn't seal the tube, it was low enough so oil could spill out and open enough that debris and water could enter the transmission. Quality isn't a consideration for Sun Valley Transmission. Two transmission failures within two years, and a bad decision of welding a corroded dipstick makes me wonder if their failure problems result from cheap, inexpensive parts, bad choices or skimping. My experience was terrible, very inconvenient, and expensive. In my case, the quality of Sun Valley transmissions rebuild was just poor.

Rebuilt my Honda transmission there some years ago, no issues with work times or the quality of work. The warranty times are somewhat limited but that is understandable.

Spoke to Steve, over phone & gave me appt right away before thanksgiving. Right to the point diagnose either transmission service or new transmission needed. Steve very courteous, friendly & professional. Brought my truck in early & was done same day luckily just service needed with adjustment but if transmission necessary I would trust sun valley transmission as very reliable & good work. Recommended!

Sun Valley Transmission replaced my transmission November 2019 for $3200 the warranty lapsed last month a month later December 2021 my car at times when I put into drive it doesn't want to drive. I put it into 2nd gear it drives then I'll shift the gear back to drive then it'll drive. I was informed today 2 year's later to the date that the sprag is failing and they'll need to replace the part and they'll need to pull the transmission to replace the sprag AND IT'LL COST ME $3200. Just to years later I'll need to spend ANOTHER $3200 ARE YOU KIDDING ME!!!!!!! SO THINK 3XS BEFORE HAVING YOUR TRANSMISSION REPLACED AT SUN VALLEY TRANSMISSION IN CONCORD ON ERICKSON STREET??????. Steve (employee) had no compassion quoting me another $3200 knowing that 2 years earlier I paid them $3200 the same amount for the rebuilt transmission they put into my car and 2 years later the TRANSMISSION IS STARTING TO FAIL 2 YEARS AFTER THE FACT. WILL NOT RECOMMEND SUN VALLEY TRANSMISSION TO NO ONE. FOR $6400 I COULD'VE PURCHASED ANOTHER USED CAR????????

Was one of the greatest experiences I ever had when dealing with a mechanic Al was very easy to talk to and made me needing a transmission alot easier and less stressful ,took it in on Friday it was ready Tuesday before closing he even offered and was able to pick me up when my truck was done. Place has got some wear and tear but what does one expect place has been there for 30+years Don't judge the book by its cover I always say you never know what you'll find inside there I found friendly caring mechanics that are the best at there jobs if you know what the inside of a transmission looks like you'll realize that rebuilding one is no easy task and not just any mechanic can do this is takes a mechanic with a special kind of skills and these guys have those skills cost me a little more than I wanted to spend but there was no hidden fees or extra cost he quoted me a price and thats what it was at the end out the door. I always say you get what you pay for I definitely got the best in a transmission and the greatest service to boot. Highly recommend you give them a try if your having issues with your transmission. Haha not sure if they do anything else I didn't even ask. That's definitely worth looking into.
