Hi i've just bought a 1992 K11 micra last week. I started servicing it today by changing all the fluids problem is when i cam to do the gearbox a ball bearing fell out when i lossed of what i asume is the fill hole. Proble is the bearing rolled inta a drain and is now gone for good :doh: Could someone tell me what it was for and if it'll be ok to runn the car without it? Also the box is quite whiney so how much would a replacement 1.0litre box be? and does anyone have one in the Newcastle area. Thanks everyone in advance
