Crunching gears

[elboro]

When going from second to third whilst accelerating fast it just crunches and i cant get it into gear until the revs come down a bit. Does anyone know if this is my syncros or what??

thanks, ElBoRo

sure is but you may want to try different gear oil , it may improve it a little .

great... so what kinda price am i looking at to get it fixed?

btw its a R33 GTS-t series 2, i don't know much about the gearbox and stuff as this is the first skyline i have owned and i havnt had it for too long.

Thanks, ElBoRo

Try some Redline gearbox oil, (there is a thread on it, do a search) if that doesn't fix it then it's rebuild the gearbox time. About $1.5K should cover in and out and a basic rebuild, as long as there is no damage to the gears themselves of course.

just curious... do you have a short shifter kit in yours?

i have in mine and i find when changing from first to second really fast it wants to crunch... i'm going to try the standard shifter in and see if it still crunches - if so then rebuild time

I've destroyed the 4th gear synchro out of mine, had chunks of metal come out when we changed the gearbox oil:D

yeh i was thinking of getting a short shifter kit.

skip the short shifter, that will most likely make it worse. Try the redline oil (made a big difference in mine), and you will find it helps if you can blip the throttle on downchanges so you get the right revs for the next gear, then the synchros don't need to work as hard.

alright cool, i will find some of that stuff n put it in my car.

What about changing third to fourth??

Mine does it not from time to time, just when lazily cruising about and then giving it a little bit of stick. It will just crunch into gear.

Worried.

i had the same problem, but it was crunching from 1st to 2nd, so i changed the oil to a motul synthetic, and it made it better for about 2 to 3 weeks than my 5th gear was crunching big time, it was such a pain. I spoke to several Gear box shops and they told me it was the synthetis oil i put in. So if i was u dont put in any type of Synthetic oil.

I got mine fixed it cost me $800.00. And i was advised to use only ( Penrite extra light ) i think its like 75w 80 or somthin like that, and its not that expensive either i think autobarn have it but im sure ud be able to get it from coventry auto parts. So dont bother wasting your 100 odd dollars on redline oil, coz in the end it aint gonna make it go away.

damn

how did they fix it? did they rebuild ur gearbox or sumthing?

[drewecrome]

the dog teeth were worn and so they had to reshape the teeth and he also deglazed the syncros coz thats wat usually happens, he said he also replaced 5th and reverse syncro. i just told him that all i have is maxium $800, and he fixed it.
