If i replace the planetary in my 4l60e transmission, will that cover the forward sprag?

Basically I'm asking if the forward sprag is in the planetary. I have a 2000 GMC sierra 1500 with a 4.8 liter vortec. I'm about 95% sure the forward sprag is busted, and I only know how to replace the planetary. So will replacing the planetary also replace the forward sprag or are they different pieces entirely?
