My 1999 ES 300 has 67000 miles on it and I am told I need a new transmission and knock sensors. ABS off and check engine light pop on. It sporadically will not downshift at higher speed. At 60mph rpm's will be close to 4000. I have done trans fluid exchanges, replaced valves, seals and air intake hoses. Lexus says they will not cover any repair because it falls out of their warranty. Every mechanic that has looked at it claims it is ridiculous for me to need a new trans with this low of miles and the great condition the car is in.
