In the ONE shot shown of the 3 years of Training (in the Manga) Son Goku is a Super Saiyan fighting a young Gohan and Piccolo.

Here's something thats overlooked: Gohan still had his short hair in Movie 5, meaning no time had passed yet, meaning Son Goku shouldn't even have been on Earth...because they hadn't even wished anyone back yet!
