low rev power (not 4wd)

i know this is not 4wd related, but i dont know where else to start. i have an older model camry (1988, SV21 motor) with an auto, and i have been racking my brains to figure out how to give it some kick at low revs.

we live at a major intersection on the sunshine coast, which requires crossing 4 lanes of traffic up to four times a day - and it is not fun when the car is sooooo slow of the mark.

at the moment, it is a really nice highway cruiser, and has adequate acceleration above 60kms per hour in second gear, but just doesnt get going fast.

am i looking at a new gearbox, or engine mods, or just a new car? (please no, this beastie has to last me another 10 years yet!!) Ideally, it would still be economical like it is, and as quiet as it is (ie stand 2 meters away at idle and strain to hear it), but just less sluggish.

any ideas, with explainations and logic for a beginner gladly accepted.

ps: as far as i know, everything is stock, no mods at all
