Not really, but it does matter how the shift lever on the transmission is oriented- if the lever on the AOD is facing up, it's for a column shift. It it's facing down, it's for a floor shift. You can flip the lever either way but involves dropping the pan and filter and I'm to lazy to go into a long explanation of what is involved. You can google it- If I recall correctly, Lokar has pretty good instructions for installing their lever- same-same to flip the stock lever. Sent from my iPhone using The H.A.M.B. mobile app
