update Well i thought this gearbox had tiptronic, so that i can change up the gears when i want, well not so. Once i shift from D to S4, its auto or S5 the same, but unlike the fords and holdens, which start at s1 and you change the gears when you want, i can leave this in S3 for example and it will upchange itself, not what i was expecting... with the sv6 holden with the 5 speed paddle shift, as with the ford i had before, i could change gears myself, all the S is doing i guess is choosing how many gears you want the car to use and it will change itself. whats the point of anything other than S5? unless im towing. very dissapointed in this feature(or lack of) but in S mode it does seem to kick down more willingly, but i dont think as much as i would like.
