yeh micky the shaft for the auto and maunal are the same and the shafts i got with the 6speed box were the same as my auto ones, but the 6speed shaft didnt have the abs rings on them so i just used my auto ones if ya get me!. If your going from manual 5 to manual 6 you dont need to do half as much work as i did, it'll be as simple as swaping boxes and then swaping out the gear shifter/cables. Theres a few g6's being broken on fleebay atm to. I would recomend it, the acceleration is emence even on standard boost but at 70 in 6th the engines revving just over 3k not sure what its like in a 5speed like but the final drives are different so can only guess it will be less. auto 1st : 3.643 2nd : 2.008 3rd : 1.296 4th : 0.892 5th : - Reverse : 2.977 Counter gear ratio : unconfirmed Differential gear ratio : 2.821 manual 5 1st : 3.166 2nd : 1.904 3rd : 1.392 4th : 1.031 5th : 0.815 Reverse : 3.250 Differential gear ratio : 3.722 manual 6 1st : 3.166 2nd : 1.904 3rd : 1.233 4th : 0.969 5th : 0.815 6th : 0.682 Reverse : 3.250 Differential gear ratio : 4.526
