Hello, when I start the vehicle, therefore the transmission is cold, it delays shifting gears, but when the transmission get heated it shifts normally, as an example, when i start the car it moves on second gear & shifts to the 3rd gear on 3000 RPM, but when the transmission reachs operating temperature, it shifts from 2nd to 3rd on 1500 RPM under normal driving conditions, note that if the transmission is cold it refuse to shift gear before 3000 RPM even when I release the throttle.
