1.9 what ? I'm guessing its a Renault /Peugeot as with a lot of automatics cars now days there is no dip stick they want you to take it to the dealers ,but a lot of these vehicles have a level plug this is fitted with a tube inside that sets the level you need to get the fluid up to temperature first put it in neutral and hand brake on with the engine running undo the the level plug if a small amount of fluid runs out and starts to trickle slowly down its up to level ,if none comes out you need pour some in until it starts to trickle out .
The engine has to be running when you do this because it is pumping the fluid around the system if you do this without the engine running the level will be short ,
If you over fill the unit it will cause frothing and damage the the unit causing air in the fluid and static gear changes ,
I hope this helps !
