Celica Forums General Discussion General grinding

Sometimes when i shift into 2nd and 4th gear i get a grinding sound, any tips on what this might be.

synchros...fun isn't it?

basically, your'e screwed dude. Buy new syncros like ^^^^ said

yeah man its your syncros! If your still under warrenty you can get toyota to r/r your tranny or fix the synchros.

i know this is probably dumb but what are synchros and what do they do. All i know is that they help take out the need for revmatching and old school double clutching. but what exactly are they? i will search on howstuffworks later but if someone can tell me let me know

could it be i'm shifting down at too high of speed?
