Secret Power doesn't exactly transform, but its secondary effect is different depending on the environment. It's still a normal type move.
Bulbapedia has the list to Secret Power's effects for all the generations it's available in. The list is a bit long to post here.
Secret Power is a Normal Type move that changes depending on what surface area you're battling on. If you were on a beach in FireRed (Last time I used it) it would resemble Mud Shot. On grassy areas it would resemble Needle Arm.
This should have all you need.
