    commdore V8 4-speed transmission urgent

    my friend came to me to edit somthing in his car's transmission

    there is nothing wrong with it but it's been tuned by someone and he put a trick in it

    when I put the gear on D1 and use sport mode, the car doesn't shift up till it passes 40 KM/H

    my friend asked me to remove this trick and I couldn't get it by the software

    please advice I'm sure you know it

    Hi,

    go to (Trans - Auto Shift Speed - Part Throttle Shift - Pattern B)

    when you open the (Pattern B) just change Throttle Position :-

    put the 0.0 from 31 to 11 mph
    6.2 from 31 to 11 mph
    12.5 from 31 to 12 mph
    18.7 from 31 to 14 mph
    25.0 from 31 to 17 mph
    31.2 from 31 to 23 mph
    37.5 from 31 to 27 mph

    I hope this will help you & give me update if oky or no.

    Regards
    Badr
