i have a major rattle/clonk comming from my gearbox, the noise is there when idling, when on the move it seems ok then when you let off the gas it just sounds awful, i also had a whinning noise, so i topped up my gear fluid, and its gone, am just stuck with this awfull rattle noise!,
Its a saphire 4x4 cosworth,

thanks cal.
