Well shift...transmission gone wrong

I think I royally screwed myself. The 4x4 gear box was seized and I tried engaging low from high. Then I tried to bring it back into high and the stick would just sit in the neutral. This is all the while that I have the gear selector in Neutral. I finally muscle it back into high gear and get driving when the transfer case pops back into neutral! I pull over tithe side of the road and muscle it back into high gear...forgetting that I was in 2nd! I hear an huge grinding noise, but am able to drive home...going through all of the gears (up through 5th). This morning I went for a little drive and nothing seems to work...the clutch is now engaging right near the floorboard and each gear is a huge grind to get into.

Do indeed a new transmission, transfer, both? Help the newbie, please...

Could be clutch slave. Have you checked fluid level in reservoir.

Or master cylinder.

Fluid is definitely low..am going to fill and see what happens. Thanks Landybandy.
