I noticed that the AUDM Barina has long gear ratios in the 5 speed, and I was wondering if anyone know how similar the Opel gearbox is, because they have shorter ratios. I looked at some pictures side by side, and they look very similar. I know looks can be decieving, so I was hoping someone could tell me whete to find the gearbox ID on my Barina so I can research further. Thanks in advance.
