Cv axle repair service near Tucson, AZ

This is my second time bringing my 2010 Toyota Camry for a trans fluid exchange . I like doing that a little more often than the book says as i feel it can't harm to be extra cautious as a transmission replacement is far more expensive . I feel so far a good job was done but the only thing I find is the impersonal feelings I get as I wanted to ask the Tech who did the job about the actual condition of the all synthetic fluid and when he test rode the car what was his thought on the shifting and general condition of the trans having 90 thousand miles on it now . I have a 25 plus year old car that I keep in good condition and I am guessing that its old school thinking with my Toyota that you bring in the car after a few days to have the fluid re-checked to make sure the level is where it needs to be . More Tech conversation would be nicer for the customer but i am guessing that if every customer wanted to ask the tech questions about there car then the Tech would get way behind in his work . I just wanted to mention that but feel they do good work for less than the price of a dealership .
