Same Problem

-   I am having the same problem, I drive 100 miles a day have a 2000 es 300 with 130K on it and it wont shift into overdrive after driving it for 45 minutes. The local transmission guy said I needed a new transmission and quoted me $3500-4000--does this sound right???? That is alot of money to put into a car that is 9-10 years old.
I bought the car 11 months ago because they were supposed to be great cars--I have never had to replace a transmission-

Lexus's have a complicated system of electronics that control the function of the transmission.Under normal operating conditions the transmission is controlled by the ecu and by a secondary system called a drivetrain control module. usually when a fault occurs it sends a code to the ecu and the check engine light comes on.
If this light does not come on then typically the electronic modulator is at fault and needs to be replaced.
If the check engine light comes on when the vehicle is hot i need this code to guide u further for the repair.
If u want to attempt the repair , be wary. its messy and takes time to do to do it right.

Usually top end gears go out first. Sounds like you transmission is in premature stages of failure. I would get an internal inspection of your transmission. Problems like this tend to get more expensive if you dont catch the early.

2003 mitsubishi montaro sport ,w, trany problems the problem is intermentant. the D light on the instrument panle does not light up half the time, and its a tricky son gun to get in gear. when you first start driving there is an RPM range fomm 2,000 to 3,000,that shakes the hole truck. as you progres down the road that range in which the vehical vibrates becomes larger and larger 2,000 to 3,500 , 2,000 to 4,000. The trany will only shift if you baby the throtel, but normaly it will only shift if you get the RPM's above 3g ,let off the gas feed, feel it shift then get back on the throtle. i tried to pull the codes for the 03 mitisubishi montaro sport,W, the first time i got: abs, po155,(o2 sensor), and some kind of short to front, and short to left. the second time: there was no data link, and i couldnt get ****. the following lights are lit on the dash: check engine , transmission, abs, and front wheel any help, or ideas would be great
