We have summarized a comprehensive transmission comparison table with technical information of each of their respective property. The main idea of this list is to get a  better understanding of the differences and to be able to choose the correct product for your transmission, and of course to have all data in one place. All dimensions has been extracted from our 3D scans, so all dimensions are from our own source, not something we collected by googling through the internet. If anything is unclear or misleading, please let us know!

Feel free to use, if you intend to host this information on your own site make sure to quote this page as the source. Enjoy!
