    Gear and Torque Converter Install/Prog ?'s

    I'm doing a friends car and installing 3.42's (A4 currently with 2.73's) and around a 2800-3000 converter. Besides scaling the shift point table, WOT Shift points, and other basic programming changes, are there other changes required? The car is not raced only street driven but with an occasional spirited cruise.

    I did mine (2.73's to 3.42's) and rescaled for the gears/tires, and shift points/WOT and it works great. But I did not do a converter at the time. Is there anything else I have to touch?

    Thanks

    Probably want to mess around the TCC lock/unlock points,
    I eliminated 2nd & 3rd gear lockup in normal but left it in
    cruise. Also did a lot of fiddling to get the lockup clutch to
    hold better, trans force motor and pressure and TCC duty
    tables.

    Sounds like this guy wants to copy my Excel tables right
    over. See the V8 General, Tuning Spreadsheets.
