    Default Toyota Platz 2004 O/D issue

    Dear Experts

    I am driving Toyota Platz 2004 Automatic ; yesterday i have changed my gear-box as the previous one was dead.
    Now after the change ; the installed gearbox is perfectly fine but the O/D is constantly off .
    means i can feel the 1st,2nd & 3rd gear but unable to switch to 4th Gear.
    O/D button is responding in Speedo meter only while its on & off position is responding same.
    Please help me out.
    One more thing there is some black sensor placed on the top of GearBox ; i wanna know the function of that sensor.

    The ECU will not allow O/D ratio or converter lockup unless the engine comes upto normal temperature.

    What engine temperature do you see when you drive normally. If its too cold the ECT sensor maybe bad and it will cause this problem.

    What ATF type is written on the dipstick? I beleive your car takes T-IV
