3a. With the clutch in I can move the DS
3b. Since the DS will turn, then I know 3-4 and Reverse are in neutral






WAIT !!!

With the clutch in ... you will be able to turn the drive shaft regardless of what gear the transmission is in.
You can turn the D/S because the clutch is engaged .. Not because it's in neutral.
