people pay big bucks to get their trannies to shift like that. That's one reason people don't make shift kits for honda's... it's because they already shift so firm. That's why they last so long. If it's a older accord you could check the throttle pressure, if that gets out of adjusment you may have harsh shifts, but i'm not sure if honda went full electronic after 93 or not. Is your 1-2 shift a little late? Does it downshift too many gears, when you nail it? What year is your accord? If it's 94 or newer check to see if it even has a cable going from your throttle linkage to your tranny, if it does and your 1-2 shift is firmer than it usually is then start there.
