Have you drained the fluid to check for debris. The 3650 is known for problems with shifting, especially when cold.
One problem is too much fluid, but you are having issues dropping into 1st. I am going to say you need a fluid change (I'm starting simple and cheap) if the fluid is clean.
I am not an transmission builder by any means. I know how the work and what each component does. That said; my guess would be a bad input bearing that is not allowing the syncros and gears to line up. You could also have bad syncros.
Does the car go into gear without the engine running? Does it shift into 3rd, 4th, 5th, reverse easily?
