I purchased a used metro a couple of months ago with a bad transmission. I am planning on buying a new one and replacing it myself. I really dont have any experience working with lawnmower transmissions but I am mechanically inclined and should be able to work my way through it. I was just wondering if anyone out there could let me know if there is any litterature out there that could give me some instruction on how exactly to replace the transmission? If anyone could help, it would be greatly appreciated!
