transmission grinding

[scions whoop]

i have an 05 tc manual, with about 57k miles on it. ever since i bought it (27k miles) 5th gear would always grind. if im easy on it, its ok. but when i wanna get up and move i throw it in 5th and it goes in but grinds.

also grinds downshifting into 1st, like when i approach a stop sign, ill depress the clutch and put it in 1st so i can take off right away. sometimes i can feel the gear turning, sometimes it grinds, sometimes it just kicks back and wont go in.

i dont really have any problems with 2-4. they do sometimes, but i think that because i dont fully depress the clutch.

someone told me the the syncros are not aligned, any thoughts on that?
i really dont know much about the mechanical operation of trannys so please dont get too complicated

got 05 tc too.. the 1st gear wont go it if you going more than 27mph. I grind going into 2nd when I drive it hard. sometime the reverse wont go in.. its known issue but no solutions.. lol.. I put royal purple in my tranny and it help lil bit

This is a known issue. I spoke with 2 Scion Dealerships and they both denied it. My suggestion is to bring it in. My car has 62K and I'm more than sure they won't fix it. So i'm just going to drive it till it breaks...btw: only shift to first form a dead stop. that's what first is for. If you want to do a rolling stop just go to second gear. Also, I use royal purple as well. Its awesome.

mine also grinds going into 3rd but if im driving normal you cant feel it, if your tryin to go fast and race you can so hear it they told me it was somethin with the clutch but who knows, maybe its a scion thing...

i dont know where i heard it, but someone said that the clutch throw out bearing might need to be adjusted farther out.
