Shudders Getting Into 1st And Reverse

[WAN73D]

hey guys need your advice/widsom again

i have an r32 gtst

i've done plenty of searching so please dont say that

and i dont have a 5 puck button clutch so please dont say that either....hehe

Anyway, lately when driving in the city my car seems to shudder quite violently when slipping into 1st or reverse. and by slipping i mean the usuall stuff, not excessive. If i give it plenty of revs then fine it'll go straight into driving normally but the clutch wont last long doin this all the time.

what happens is that after a while of driving the slippage is replaced by shudders as if the gearbox/clutch/engine are about to jump off. but when cold its fine, also once into gear and driving it drives sweet.

through my searches i have seen someone who had this problem and it was the master cylinder, they had also found oil around the clutch peddle. i just checked my clutch peddle and on the back of it i pretty much have a whole oil refinery!! so i'm thinkin mstaer cylinder has popped it

i just wanna ask is this a likely culprit for shudders gettin nito 1st and reverse (WHEN car is HOT)

also how much are these

and will it be a lot of work to replace

ps my clutch is only 1 yr old...some sort of PBR sorta H/D thing.
