Go out of their way for you. Car was stalled out 1 mile away from shop and was not going to make it to the shop before they closed. They waited for me 20 minutes after they close to put my car in their shop overnight

Go to AAMCO! I had a diagnostic code for a bad output sensor. My Transmission was in Limp Mode. Sierra Transmission recommended I get a whole new Remanufactured Transmission. Quoted $3,600-3,800 over the phone w/o even seeing the vehicle. AAMCO FREE Diagnostic, $189 to take it apart and check for sure(goes toward repair) replaced Sensor$250 out the door, parts& labor. Runs smooth.

i was drawn in by their friendly attitude. this is a great thing for a business to have. And Tony, the tech who offered great advice and was very helpful must be a blessing for Chang the owner. ok now i was in need of a part repair which they offered to do, given ofcourse no guarantee was offered and i did agree to this. i did find out the hard way after paying $250.00 for having a part disassembled, cleaned and reassembled. i was naive in assuming this was of any good. i even purchased a new part for them to do the job which Chang showed me was in questionable condition. i took it upon myself to find and purchase this part because Chang the owner told me parts for this are unavailable. upon further research i came upon information regarding the process of working on this part. to sum it up i find it hard to believe someone who spent a day researching this has more knowledge than a professional shop dedicated to specializing in this work. people please do your research before hiring any services! the information is out there.

Chang is the man. Took my Jeep in to get an external transmission cooler installed and it was a great experience. Quoted me a very fair price, did the work super quick, and delivered great customer service. I’ll be back.

I came here and found out it was a oil leak and not a transmission leak. They stated they changed front and rear seals. After going to another mechanic they stated none of the seals looked like they were replaced. 750 dollars because they said they had to move my transmission. The other mechanic I went to said he did not have to and fixed my oil leak for 600 and bought the correct part. This is a perfect example of a mechanic who will the advantage of people. They likely spent no time on my vehicle yet changed me 750.

Great place. I was in desperate need of rear rotors and brake pads on my Ford explorer. I showed up half hour before closing time and he still was willing to help me out. He Went to pick up the parts personally while his guys tackled the tare down. Price was more than fair, great service. His guys are great. Thanks again.

Best shop around town! Super easy to communicate with. Got my truck towed in. A day and a half my truck was finished. Very professional. The price was right. Smooth transaction. Got my clutch and slave cylinder replaced. Totally recommend to anyone!

Great place to take your transmission. They are quick and do good work, and they actually got my wife’s godawful VW Touareg to shift relatively smoothly after years of super-hard shifts. Highly recommended.

The owner of the shop was excellent in keeping in contact with me throughout the process of getting my clutch replaced, and identified a leak in my main rear seal (an issue I had already figured was happening). The price for the work was very reasonable, and the entire job was completed in a single day. I would totally recommend anyone needing work done to give them their business!

If i can give this place a -10 star i would. HORRIBLE! My car was sitting in my driveway for 2 months, It started perfectly fine AND still drove, the only reason why I wasn’t driving it was because there was a loud knocking sound and I didn’t want to risk messing it up anymore. Last week I got my car towed to this place for a diagnostic, I started my car the morning of and backed it out my driveway so the tow truck can pick it up. The mechanic or which seemed to be the manager, STARTED my car and DROVE it to the area where he needed to check what was wrong with my car.. He called me a few hours later and told me my car was ready for pick up BUT it didn’t start or drive anymore. How all of a sudden my car doesn’t drive or even start up anymore !? he said there was nothing he can do and made very disrespectful comments to me saying I don’t know anything about cars but my brother does, clearly saying that because i was the only girl there. Do not come here !!!

Took my sister car here last week for a diagnostic, car was dropped off and was running perfectly. They called us a few hours later to pick up the car and they let us know that it wouldn't start anymore. Had to get it towed back home. Recommend taking your vehicle somewhere else for any work. One of the workers was very rude and unprofessional making smart comments to my sister letting her know she can't say anything about cars because she doesn't know about cars but that me (her brother) knows about cars because I'm a guy, assuming he said that just because she's a girl. I RECOMMEND TAKING YOUR CAR TO ALL-STAR TRANSMISSION FOR ANY WORK!!!!!

After having a completely ridiculous experience I now feel that this shop was just trying to scam me and run away with a quick and easy buck. I took my Nissan Titan in as it had intermittent issues with the transmission disengaging starting out from a complete stop, A/T check light blinks on and off, goes off, then the check engine light comes on and stays on. I pull over, put it in park, turn the engine off, start it back up, and drive off like nothing happened. The transmission shifts and operates normally. I drive it easy for a month or two, check engine light goes off and its fine until the next time it happens. I took it to useless excuse for a shop. They worked on it all day. They called me up and told me I need a whole new transmission and a remanufactured transmission would cost $7500 and a used would be $3500. I asked how much to repair it, and was told also about $3500. I immediately started looking around online, and found used transmissions for under $800 with free shipping and remanufactured engines are typically about $2800 for 1st generation Titan 2WD. The code that was showing from the check engine light was a solenoid error - P1767 which is part of the valve body. To replace the valve body, its just under the transmission pan and valued at about 1-2 hours labor. A remanufactured valve body is about $250. A new one is about $1800-$2300. None of the actual numbers I found remotely matched up to what I was told... who ended up being the manager of the transmission part of the shop. I then took it to another shop who looked up the code, and told me that its most likely an electrical issue due to the nature of the problem. They also pretty much confirmed all the prices that I looked up and found. Bottom line is, DONT EVER TAKE YOUR VEHICLE TO THIS SHOP - THEY ARE CRIMINALS!

After taking 5 vehicles here for service, I learned on the last car that they use aftermarket gaskets which resulted in an oil leak. In addition, I had to pay for the new original equipment gasket so they could replace it. Lost time because I had to drive back and forth to drop off the vehicle and pick it up. If you go here, do yourself a favor and ask for better quality parts in order to avoid further expenses.

I have been a customer since 1994 I have never met a more honest person in my life. Over 30 years of service I trust and appreciate Chang and his employees.If you want fair pricing and honest assessment Sierra Transmission is the right place.
