I brought in my crappy 1989 minivan for transmission problems. They talked me through all the different possibilities of what could be wrong, and did not push me toward taking any action. In fact, they told me to hold off on changing the transmission fluid until they had a chance to test drive it and check it out. Then he ended up putting 3 quarts of transmission fluid in my car for FREE so he could see if it ran any better. It did. All the diagnostics, test drive, advice, and fluid was free. They called me at every step of the way to get my consent. I ended up deciding not to do anything, given the age of my car -- and so I picked it up full of transmission fluid, without ever paying a dime. Honest, thorough, professional, and will not force you into anything. If I were going to stay in LA, this is where I would bring my car!
