now he ask me to drive back and see how, but the problem still the same.
Anyone experience this before? or know why is it like that?
Please help

First of all, I wouldn't use the so call synthetic fit to all ATF. Every type of ATF has different viscosity modifier and additive which it fit for specific vehicle. How could a 'fit to all' ATF meet the criteria for every transmission. For an example Hyundai SPIII indicates "lock up clutch" on their label so there must be something is different from the other for example dexron III. Btw, isn't all ATF are synthetic?
A dark color drained ATF does not means the ATF is overdue. Most of the time it just that it is doing it job cleaning the system. For example SPIII and Toyota type IV tend to cleans and get dark easier than dexron III. As long as no burnt smell it should be still fine if replaced every 40K km under non severe driving condition. Even Hyundai handbook shows that dark ATF is fine.
I suspect the transmission solenoid is probably stuck. And yes listen to the rest, go get the car scan for AT fault code. An honest work shop would charge around rm40. A cut throat shop would charge about rm80 or above.
