I bought a used 2004 Mini Cooper S (R53) with a 6 gear manual transmission about 3 months ago. The reverse is to the left of the 1st gear, and ever since I bought it it was hard to put it in reverse. At first I thought it was something I needed to get used to and I kinda did, but it srarted to get harder and harder to put it in reverse. Today I couldn't get it in reverse at all. I think the problem might me in the gearshift linkage, but I have no idea how to check this. I would like to fix this myself. Any and all help is greatly appreciated.
