yeah dude its your synchro.. I had the same exact problem before I got my tranny replaced from Toyota under warranty. When you shift normal through 4th it doesnt grind but when you downshift from 6th and 5th gear, that shit just grinds ugly. Yeah so what year is your car? and how many miles you got on it?
yeah man its your synchros...well when i got it done, i saw the prices for the parts and all. It was like over 2,300$ U.S. dollars and thats not including labor. but if you can do it yourself, then more power to you.
