    How to Quickly convert shift table?

    I have a 2004 mustang gt

    In the passed when I'm running my 4.10 gears I simply did 3.27(stock gears) - 4.10 = 0.83 and multiplied each table by it.
    Whats the easiest method to convert either table to 3.73? Tried 3.27-3.73= 0.46 but thats like 50%.

    Sorry really bad with math
    So bad in fact ill paypal 100$ for the working answer lol

    Take the bigger number divided by the smaller and it will yield the percent of change. 4.1/3.27=1.253 or 25.3% more gear. Just remember anything above 1.0 is the percent increase and anything below it is the percent of decrease. If you ended up with .73 that'd be a 27% decrease because .73+.27=1.0 You can also do .73-1=-.27 or your percent in change.
    By doing subtraction like you did it yields the physical size change not the percent, but you could find the actual percent by taking the difference in subtraction divided by the stock value, times 100, and get the same number, (.83/3.27)*100=25.3 or a 25.3% change. Remember PEMDAS or order of operations for math if you're going to use a calculator.

    I managed to get that set. Now i'm having other issues.
    during upshifts at certain speeds and throttle its bucking hard into gear.
    i already bought and installed a new transmission still did it
    then noticed the torque converter apply speeds especially 4th look really wierd.
    anyone able to look at that for me?
    afraid my dyno tuner did not correct it.
