Sun Valley Mercedes Transmissions, LLC

Sun Valley is the only Mercedes Transmission repair shop to trust your car to. My car went into a safety feature and would not let me drive past 20 to 30 miles and hour. I took the car to Mercedes Calabasas. I explained what the car was doing. They gave me a courtesy car for the day. I called them by the end of day and they told me they could not figure out what was wrong with my car. They were going to give it to the master technician. Long story short 6 days later Mercedes Calabasas told me they think it was the transmission control. They quoted me $ 1000 to fix and then they would get the proper codes to the car to see what the problem was.
I told them I would call them back later to let them know what I was going to do. I started calling around and found Mark from Sun Valley Mercedes Transmission. Right away Mark made me feel welcomed and put my mind at ease. I explained the whole situation with my car and Mercedes Calabasas. He told me to bring my car to him and he would be happy to give another opinion.
I dropped the car of the Mark and by the next day he called me to pick up the car. He told me the car was fixed and it cost me $ 150. He saved my a lot of money and time. It was the wiring and harness had started frying. That was why the car was in Limp Mode.
Mark is an amazing Mechanic and Owner. He is always willing to help or give a referral if he does not do that kind of work.
Funny Mercedes Calabasas a large Mercedes Dealer could not fix my car after 6 days and Mark fixed it in 1 day for a lot less.
Trust him he is the best.
Thanks Mark

I would like to thank Mark and his crew for doing an excellent job on my S550. They are the best when it comes to Mercedes transmission.

The best decision I’ve ever made!!!
First up, shout out to the owner, Mark. You are the best. I scored 5 Stars because Unilocal don’t have anything higher than that. ;)
I have a MBZ E500 very well known to have a notorious tranny problem.
(German cars. And you’d think that’s the last thing you’ll ever hear from a German-​made cars. Yeah, sure)
Anyway, first took it to FJ, an MBZ dealer in OC and have them diagnosed it. Found out it needed a new or rebuilt transmission. As expected, I was quoted an astronomical price on the replacement. So, I Googled to search for alternative & found SVMT. Went to their website I found out they only rebuild MBZ transmissions.
So I called & talked to Mark (owner) and asked him if they can also do the labor on the installation. And he said YES.
To make the story short. I now have my car back w/​me with 2-​year unlimited mileage warranty and at a fraction of the price quoted to me by FJ.
But that’s not all. They have a very clean facility and professional repair men. I couldn’t have felt any comfortable dealing w/​these guys.
Will I recommend them to my friends? Hell, yes.
I would even recommend them to the people I hate. ;)
Thank you sooooo much SVMT.
