1 2 3 Drive or just keep in drive
1). Upshifting from 1 to 2 to 3 is fun (almost like simulating a manual only without a clutch). But it adds a little extra wear and tear on your tranny so should be done in moderation (if at all).
2). Downshifting manually (like putting it into 1 while you're doing 35 mph) is VERY, VERY, VERY bad and should not be done at all. Alot of guys still do it if they are caught in a spur of the moment challenge on the street but I still recommend against this.
3). Shifting manually at the track will NOT make your car faster in the 1/4 mile. If it does then you have transmission or tuning issues that should be identified and corrected. D or OD and letting the computer do its job is generally considered the best way to drag race.
4). Avoid a 3 to 4 shift at WoT. This is also very bad for the transmission. 2.73 geared cars need not worry (shift occurs at over 160 mph). But 3.23's need to watch out on spirited highway runs. This shift happens somewhere around 135 mph. This has nothing to do with manual shifting but I thought I would throw it out there anyway.
Hope this helped you.
It's fun to do the 1-2-3 thing yourself on occasion. Just don't get carried away with it and your tranny will last longer.
