i was wheeling out in my land rover. and i was in drive going through some stuff, and it started to sound like it was loosing traction, like it was really muddy. and then it started to rev so i put it in 1st, and then it drove right out of there. so once i got out of there it wouldn't go into drive. it works in 1st and reverse, but no drive, 3, or 2 what might have happened to make me loose those gears

 

Send me your tele number and a good time to call, I'll call you. You have a major drive line issue.
