I'm assuming you have an automatic trans. You must use SPIII, which you can buy only from the dealer. I haven't seen it aftermarket yet. Mitsubishi and Kia use the same fluid, so you can buy it there as well. Part # from Hyundai is 00230-11000, and it lists at $5.54/qt

I hve changed me gearbox ,its automatic trans,But I thn fiilled it up with ATX and nw @ times if you put it on drive it wont move ,it only change to other gears so i will have to put on lower gear then put on drive later after it has driven for a while,but Its also rough when changing from lower to driver or to reverse.do you knw what might be the problem?

If you weren't have problems before you changed the fluid, you probably damaged it by putting the wrong fluid in. On these cars its cheaper to put a reman transmission in them from Hyundai than it is to have it rebuilt. At leasts thats the way it is here in the states, not sure about the UK though.
