alright so i'm running a 5s-fe with the stock manual transmissinon
as i'm upshifting, every gear goes in fine, for the most part
but as i'm downshifting, specifically from 4th to 3rd gear, if i'm going above 25 mph, my 3rd gear grinds bad.
i always make sure i press my clutch all the way in so thats not the problem. and i've even tried that whole "double clutch" technique, and that didnt fix the problem either.
can you guys tell me whats up with this? is it something to worry about?
also, but if my car's really warm, like if i've been driving around for a while, the downshift grind to 3rd goes away!
so what's going on?! thanks in advance for any help

helpp pleaseeee!

Synchros going bad. Too much high revving and forceful downshifting. Nothing can really repair this other than part replacement. I suggest you either live with it or replace your transmission. These parts cost more than a transmission and taking apart the gears to get to it is something that a DIY mechanic cannot do. FYI better gear oil is NOT going to help. You cannot replace broken metal with lubricant.

thanks for your help, soulshadow
appreciate it

changing with better fluid wont fix it but it will make it less bad, I put Nulon gear treatment in mine with new fluid and it is alot better but of course still does it.

thanks for the heads up man
i will probably do the same for the meanwhile
