yup. kasi pag city driving mabagaal lang arankada di ba, so the computer (of the tranny) memorizes this style of driving and thus it shifts early. sometimes even if you floor the gas it will hesitate before it downshifts. pero after disconnecting the battery the memory is erased and the computer starts from scratch again, no "city driving habits" in its shift pattern. mas maganda arangkada as it stays longer in gear, downshifts readily when you need to overtake, etc.

pero of course this assumes that your highway driving is different from your city driving. if you drive the same way then bale wala.
