03 STI crunch into 5th under hard acceleration
 

I've read quite a few threads on here already but can't find one that's similar to mine. I only bought the car yesterday (private) and didn't drive the car hard on the test drive, but coming home I noticed under hard acceleration from 4th to 5th there's a small notch/crunch. It's fine under normal acceleration, but pretty much every time under hard throttle it'll crunch.

Any ideas what this might be please? From what I can see it might be the syncros; if this is the case any rough costs? I'm based in Kent if that helps, but willing to travel to the right place to get the work done if needed!

Check oil level,you could even try an oil change with decent stuff before you go down the gearbox out route.
At a guess,with new clutch and referb gearbox you won't get much change from £800

5 speeds sometimes need nut tightened on the end of the input shaft in the transfer casing.

Have a read of this thread, it may give you a few pointers on cost.

I paid about 500 + vat for removal and refitting.

I agree with the above though, try an oil change first :thumb:
