as above was just wandering if any of u guys have suffered the above when raging it through the gears as i have experienced this a few times now and just wandered if it was a common problem on the 6 speed and what was the cause or its just me rushing up the gears and need to learn how to change gear properly lol the cars done 31k and had the oil changed at subaru at 3ok :thumb: just realised i posted this in the wrong section lol

My 6 speed has never done it, would change the oil again to syntrax to see if makes a difference.

I had probs with my 03 sti 6 speed box. Started with 3rd and 5th gears @ 55k miles. Warranty sorted that out then only last month the same has started with 6th :(

Hi, had this problem on MY03 WRX shifting between 3rd and 4th, it was the "syncro's" between the gearing, lucky for me it was under warrenty, subaru said it would have been around the £1800 for new syncro's and the labour. .. ouch!!

save your money its a mechanical problem,if you can live with it just treat it gently or alternativly go see the bank manager

I thought i was lucky as it happend to me while i had warranty, but 10k later the 6th gear is now crunching. Should of had a new gearbox as it is a fault and not just new syncro's. My main dealer agreed, to late now though:(

Should only be looking at a £500 rebuild though :)

£500 rebuild where from??

i mite be needing one off them soon... 340bhp & 320t wrx 5 speed

Theres a similar post in the general section.

I found doubling the clutch stopped the crunching when driving at high speed.

Had a 250 quid warranty and they paid the 750 plus vat for an exchange box at Scoobyclinic, mines a 2003 WRX

I also have an 03 STI - and have had crunch in the 4th to 5th change when moving through the gears quickly. If you deliberately pause in the neutral gate, just briefly then it does not do it.

However, 6 months ago I had the Subaru quick shift kit fitted - and have not hade the 4th to 5th crunch since - not that I have noticed.

It might be worth trying this before shelling out on gearbox work.

cheers for all your feed back seems to be abit of a common problem then.
(If you deliberately pause in the neutral gate, just briefly then it does not do it.) i have thought this to dave.:thumb:

Red man, I've had the quick shift fitted and its still done it - other thing I'm going to try is changing the oil to semi Castrol which is ment to help the syncros loads...so its just a matter of time before she'll crunch again I'm afraid.

I'll try that pause on shifts but it will mess up acceleration a bit.
