i wouldn't want to deal with the dealer mechanics but this seems like kind of a big job. I'd rather go to toyota specialized shops since it seems like a big job. I want to drain and replace ATF but I heard people say if it hasn't been changed for a long time, it is best to leave it alone. I also saw a video on youtube where the guy drained ATF like 4 or 5 times to almost completely replace the whole thing. Is there a reason you went to Toyota for the ATF change? As for the burning oil, I haven't noticed anything. The reason i needed to top off is becuase the shop didn't put enough (i think they only put 6qt).
I would stay away from Toyota dealers.. I also have an 08 LE, I bought it at 85k about 6 years ago. It now has 112k miles. In that time, I have redone front and rear rotors and pads, changed all 6 spark plugs ( and 3 rear coils ), numerous oil changes, and the only thing I did at the dealer was a trans. fluid change. I did all that around 100k miles, give or take. The rear spark plugs and coils showed no signs of wear when replaced. Oh, and definitely change the PCV valve every couple oil changes. I was losing about 1/2 qt. of oil between changes, and my mechanic suggested changing pcv valve. It was so clogged, you couldn't hear any rattle. No more oil loss after changing. I live near Rahway Prison, and I won't take my car to anybody except one shop. I can bring my own parts, he is VERY FAIR in price ( 275.00 for spark plugs and rear ignition coils changed ) but I brought my own parts. If you want his shop address, send me an email. grateful908 gmail.
