just a quick question. what is the standard gearbox upto power wise?

ive just had my car chipped and its still on the standard gearbox.

if its likely to die then i would rather replace is sooner rather than later.

im running 175bhp 191lb/ft.

also what about the standard clutch? i think it may have started slipping recently but i can't really comfirm that until i fix the leaking oil from my rocker cover...

thanks!
