20 percent failure on a luxury car is rediculous. I did service at 30k intervals, with filter screen and gasket and drain. I do not tow, My wife commutes down a busy road everyday about 13 miles. The fluid from day one change at 30k, 60k, 90k was black and burnt. Completely rediculous. I have not had time to set up my survey locally but I will. Monarch says my changes are not good service, I say bull@#$. I serviced my Lexus meticulously since the day I bought it in November of 1998. Funny any detroit car tranny doesn"t get burnt, black fluid, even when they fail. So what gives, Lexus is trying to hide this crap, and sneaking 15k service in now which is not even mentioned for severe service. What a crock. I am happy every one is not experiencing the failure, I would never wish that on anyone, I work hard for my money and $4300 dollars for a fly by night rebuild is rediculous. Then I had to have that one changed, because it didn"t work right. To top it off the Roseville Lexus dealership nearly jeopardized my wife's safety by doing substandard work, for instance leaving three of the bolts that hold the tranny to the engine out. Then the next transmission leaving the sway bar ends unhooked and rubbing against the drive shafts and brake lines. What a wonderful customer experience. I have worked on cars all my life, raced them, and maintained them and never made mistakes like that. And all Lexus said was s o r r y. Big deal. I told the shop steward, service manager, and general manager they were complete idiots. Went out to the shop and inspected my vehicle the last time and still found crap not right. Two weeks later the axle shaft fell out because they broke the retaining clip after removing it twice. What a bunch of shade tree mechanics. Send them back to high school auto shop. So yes, angry is not the word, but I continue to try to assist my fellow Lexus owners with my expertise when I can. Good night.
