I found Carlsbad Auto to be very reputable. My Ford Explorer was having major shifting problems. This was the third time I had major transmission issues with a $3000 replacement being hinted at the dealer. Even though the transmission is sealed, Craig suggested they disconnect the trans cooler line, pump out the old fluid and feed new fluid into the intake line, while it was running, along with a trans cleaner fluid. They drove it around a few miles, drained the fluid with the cleaner and refilled it with new fluid. It worked! Shifts great for $285 instead of $3000 for a replacement trans. I'm new in town and already found my "go to" guys!
