My mechanic said he replace 3 oxygen sensors each time just enough to pass California smog check. Since I have been to him twice and If there are only 6 sensors why was he not able to permanently get ride of the "service engine now" which cause the smog to fail according to him?
Secondly, since it is 131,000 miles, my next smog check is Sep 2013 so should I just trade in the car which is now worth less than $1000 instead of passing it?
Third, if KHLow stated the filter is in the transmission and a non-maintenance item, I assume he is saying it is not necessary to cahnge it?
Fourth, is it true that a drip and replace better transmission flush because it completely drain all fluid and clean out the gunk from the pan which need to be open and reseal properly whereas flush is by a machine sucking only 40% fluid thru the dipstick funnel and putting it some new fluid?
