I called Downtown Auto Repair while on Highway 5 from San Francisco to Seattle. The "D" light indicator on my dash began to blink. The very nice guys at Downtown Auto not only made sure they could fit me in to take a look right away, they adjusted my expectations, saying it is probable that I'd need to stay the night in Eugene as it could be a transmission issue. I checked 2 other places to see what they had to say, if they could get me going faster, and both said it is definitely not advisable to continue the trip and also they had no availability...Downtown Auto called me just as they were closing and told me the diagnosis - they needed to source and install a new pressure switch. They were able to do all of this by the next morning around 10:15 and I was on my way. Definitely turned what could have been a frustrating wrench in my plans into a slight and manageable delay. Honestly, the most pleasant a car trouble scenario could have gone on an 800 mile drive. Thank you Downtown Auto Repair!
