Guitron Auto Sales / A & Z Transmission 11810 Valley View Avenue, Whittier, CA 90604

"Good service, good prices, honest owners and employees."

"Started with a check engine light. Had my car checked out by Ivan and he wanted me to change my whole transmission when really it was just the transmission sensor (my car is a Nissan Sentra and the transmission that Ivan wanted to switch out was already new so I knew something wasn't adding up.). I asked him to ONLY change just the sensor which they did but not only did they do that they also unplugged my fan for the motor making my car overheat. Once he gave me my car back it ran great for the first 15 mins then the check engine light came back on. I got home and I tried to turn it back on but it wouldn't start. I had to send my car to our family mechanic where he ended up showing me that Someone from this location sabotage my car so that they can get my to drop 4k for a new transmission. I would have given them 0/5 stars if it was an option."

"They do an awesome job on my car everytime, but they need to answer their phone calls. Just saying."
