Man I am telling ya, I have a 2003 Lexus RX 300, it is won't shift to overdrive at all. I brought it to my regular mechanic in Aloha, after a day diagnostic they called me and told me that my car needs new transmission and they don't do it there so they are recommended to there friend transmission shop. Get what, after $3000 later, with rebuilt transmission, my car still doesn't shift to overdrive. So they were running out of clues and send me to Canyon Auto Repair. After diagnostic, they found and fixed he problem just like that. My car now shift to overdrive very smoothly and the gas mileage are much better now. Thanks God, after fuel go up now almost $ 3.50 per gallon. I forgot to say that these and at Canyon Auto Repair replaced both Knock sensors and wiring harness, the Mass air flow sensor, The bill just under $900. I called Lexus dealership to compare the price. get what almost $1500 with the same works they did for my car. I have found my mechanic. eventhought, I had to go throw very painfull experience with $ 3000 tranny rebuilt.
