going at 3rd at low speed such as at 50Km/h or below, as soon as i take off my foot from the gas pedal, it shifts 4th. Why is this?would adjusting vacuum modulator help in this case.

car should be driven at high RPM or Low. Which is better.

Would changing ordinary ATF with good fluid(synthetic) and filter help in smooth shift.

Driven on a gentle throtle the 4 speed 'box will change up at about 1,500rpm.
In 3rd gear, when I lift off mine will also change up to 4th gear.
I think it is to save a drop of fuel and does not provide any engine braking if going downhill unless you manually select a lower gear.

I have a 2002 c180 coupe and i have the same type of problem, the box likes to change into the highest gear it can at the lowest speed it can. I find i 'm fighting with the dam thing all the time, when traveling at about 30mph and you hit a small incline, the revs drop to just about 1100rpm before the box will change itself. Then once you get the speed back to 30 it changes back to 4th and so on and on and on
