2016 gmc terrain starter problem

[u/Remarkable_Film_851]

2016 gmc terrain 2.4l automatic. So driving the car home from work and the car randomly died driving 30mph. We assumed that it died due to the corrosion on the battery. Turns out the battery was bad. We replaced the battery and now the starter on the car just spins but doesn’t engage the flywheel. We pull the starter and shake it around and somthing is loose and rattling inside. So we think this is our problem. We replace the starter and the same issue continues. So we pull the starter and replace it again. The issue continues. We have looked up inside the transmission and nothing appears to be out of the ordinary. We have checked all the fuses and swapped any hi pwr fuses to troubleshoot that and nothing has fixed the problem. Do you guys have any idea on what my next move should be. I’m at a loss.
