Major service, Transmission fluid, oil etc Options

[Euphoria]

Hey, I just went and bought some stuff to do a major service I got Mobil 2000 10-40w semi-synthetic, valvoline synthetic 75-90w manual trans fluid, fuel filter, oil filter and Nulon coolant.

Now my question is, in a thread someone said valvoline trans fluid was awful but the problem was I couldn't find Pennzoil anywhere, the only options were valvoline/castrol synthetic or normal. So should I just use the valvoline or swap it, will there even be much in it with vavoline or castrol.

Ive been using castrol 15-40w magnetec for sometime now and the last owner did too so I wanted to see what difference there was with another and everyone said Mobil 1 but that being $80 here in australia I just got semi-synthetic which was half the price, anyone used this oil before?

thanks.
