What you watched was the funimation dub, or you haven't seen it. It's that simple. Funimation outsourced the dub to the ocean group studio (canadian) for DBZ, but eventually decided to setup an in house dub studio. It's funny cause in the original funimation dub start (which was the ep ginyu assault) they still mimic the voices of the ocean dub. Sabat mimics Brian for example.
It's specifically the episode Ginyu Assault, which is where burter and jeice attack goku. So technically it's a little after the ginyu's arrive. Between that ep and what the ocean group notes is the 108's ep 'goku's special technique', there is no ocean dub. So there is no ocean dub of goku going ssj for the first time for example (released anyway).
I have NO idea why the ocean dub didn't go back and start from where they left off, other than that they started at where the series was in terms of airing at that time. But they never went back apparently.
