the car does not shift into the last gear every time. to get it to shift, i stop the car and turn the ignition off and re-set the computer, it will then shift. i have had the car diagnosed for a solinoid problem..it checked ok. i have had the transmission flushed and serviced. i have been dealing with this for 9 months. mostly because it's going to cost a lot. especially if i take it to a lexus dealer. frankly, i can't afford to do that. it drives beautifully as long as i don't have to stop much...and the funny thing is, this does not happen every shift...maybe every 3-4th shifts. help!!!!!

  I had the same problem on my Lexus RX300. I replaced the knock sensor and the problem is gone. It has been trouble free for over a year.

• At 60mph the rpms are 4000; normal range 2500 what causes this.
  Check engine and VSC light stays on. Mechanic cannot pinpoint the problem.
