I bought my ex Japanese car in 2011 December. Its a Toyota harrier , 4 wheel drive and is automatic. All along it was OK . the problem started in 2014 around August. it has difficulties in going to gear 4 from three. when i start it it can go to all gears up to 4 but if i lower the gears or stop it wont go up to gear 4. it will switch on the engine light and refuse . i have wasted money on the car but its not helpful. i changed the gear box but no improvement. i have also changed the air flow sensor but in vain. I took it for diagnosis when the engine light was on and it showed the error " Knock sensor in bank 2". many mechanics have changed sensors too many a time but nothing have helped. i took it to one special mechanic last week and he said i should buy new ATF oil ( gear box oil ) and a new knock sensor. i haven't done so but my heart keeps telling me that nothing is going to improve.
what really could be be the problem ?
i thank you very much for your cooperation and helpful answers.
