Grind going into third, drivetrain woes

[clean2g]

Arghh WTF.. now the grind in 3rd is gone but all of a sudden starting today I have to force it to get into 2nd and I have white smoke on start up along with some nice burning smells.. Kinda like the smell my brother had when his rings were going bad in his prelude. It's a sweet mixed with rich burning smell. I am currently using royal purple 75/90 I believe in the tranny. Checked fluid levels a today and checked for possible coolant in oil but couldn't see any. I'm lost and ready to dump this thing.
