Hi Dear
As above discussion, I am doing R&D on this topic. What I conclude: First of all visit these website below:

What Causes Hard Shifting in an Automatic Transmission? | eHow.com
According to my results:
1- Our Mechanics are totally Illiterate. They don't know what is Auto, Manual, CVT, HWT..etc. They just only know what they learnt from USTAAD.
2. Every Vehicle has its guideline to maintainance after R&D.
3. The System in Vario 2004/2005, is CVT. Auto Transmission. The brackdown of this system causes;

[U]Symptoms Indicating Transmission Issues
[/U]If you don't want to be ripped off by car repair shops, you need to know how to carry out transmission problem diagnosis. An accurate diagnosis requires knowledge of the inner workings of the transmission. It would be a good idea to get hold of a Hayne's manual, specific to your car model. It will provide you with an overview of automatic transmission working and also provide some maintenance tips. Here are the most common symptoms that one needs to watch out for.
Rough Shifting of Gears
One of the prime symptoms is rough shifting of gears. Instead of a smooth gear transmission, you will find that the transmission is bumpy. If you notice this happening repeatedly, it is time to get the transmission checked.
Delayed Engaging
If you notice that the gears are delayed in getting engaged and there is a latent response from the transmission, the reason might indicate a problem with the gear box. This condition may be a result of multitude of causes. One of the most likely causes might be low transmission fluid.
Murky Transmission Fluid
If you notice that the transmission fluid is looking murky, it means that a lubrication fluid replacement is on the cards. An immediate transmission fluid change is recommended.
Transmission Slipping
One of the most common problems with car transmission is recurrent slipping when changing gears. Transmission slipping can result from low levels of lubrication fluid or structural failure. This is one of the prime problems that plague an automatic transmission. This car problem needs to be addressed as soon as possible.
Transmission Fluid Leak
Checking transmission fluid should be a part if your regular car maintenance schedule. A leaking of the transmission fluid is one of the major indicators of imminent automatic and manual transmission problems. Make sure that you get the fluid replaced, as without it, the system will eventually break down. Lubrication is an essential need of every working machine part and the most essential necessity of the transmission.
Transmission Noise
Due to prolonged wear and tear of gears due to low transmission fluid levels, knocking noise may be heard. This noise is indicative of imminent transmission failure. A transmission fluid refill may take care of the problem quite easily.
At the slightest indication of any of these signs of impending transmission failure presenting themselves, you should visit a car repair shop, as soon as possible. Delay in doing so, will ultimately result in costly car repairs. Make it a point to include car transmission checkup, in your regular car maintenance schedule.
After all my research kindly advice.
