Hello! My Toyota Estima 2002 automatic has the same problem:
The vehicle will not shift into fourth gear sometimes especially when the vehicle is driven for some time.
When I start the car in the morning to drive, it’s OK to shift to gears 1-2-3-4. When it’s in gear 4th, if I just keep driving (>80km/h) then it’s still there, meanwhile I try O/D button => when I press O/D OFF I can feel the vibration a bit then RPM goes up (to 4000 at 100kpm), when O/D is on the car goes back to 4th gear normally (even try many times).
But when the car slowdown (down to 10-20km/h) then go up again, it will never get back to 4th gear, but bht only 3th gear (then the switching O/D button can just turn on/off the O/D light without any change of driving the car...). I also try to stop the car, turn off, then turn on the car again, then gears can just move from 1 -> 2 -> 3.
I am trying all the instructions mentioned above to see if any of them works on my car.
