I rachet shift 1st to 2nd @ 5600 then 2nd to 3rd @ 5400. If you dont know what rachet shifting is, put in 1 press gas pedal to the radiator shift into D for 1 second holding button on shifter and go back to 1 this will lock trans. into 2nd then D when you hit about 5400. Hope this helps, BTW I'm still playing w/shift points at the track

There's still a debate out on the rachet shifting. Some people do it for years with no problems, others try it and the tranny goes.

I use it, and it works, but I only use it at the track or in racing...maybe the occasional sprint to 70. I wouldn't use it everyday if I were you.

hey, i just put this in another post:

you like dancin? you better, cause its time for...The AOD Shuffle!
ok, start by putting your car into 1 (alllll the way down, press the button and put it back). put your left foot on the brake, and use your right foot to bring the revs to ~1000. when you are ready to go (don't sit like that too long, it will burn up your converter) release the brake and slowly depress the throttle. when the revs hit 4800, push the "gear selector lever" (i hate my auto too ) up one notch (to the "D" position). the tranny takes about 300 rpm to shift, and once it has fully shifted, and youve waited a second, press the button and pull it BACK to the "1" position. when the revs hit 4800 again, put it in "D" and leave it there. finally, when they hit 4800 put it into "OD", but by that time you will really be movin....i do the entire 1/4 in 2 gears, going just out of the powerband on my 90LX convert.

a stock mustang stops making power at about 5100ish,so given it takes 300 rpm for the anchor to shift, you move the shifter at 4800. your AOD has 4 gears, the "1" position only lets the tranny use first gear, the "D" position lets it use the first 3 (1,2,3 DUH!) and the "OD" position lets it use all 4. the problem is that if you let the transmission shift itself, it does so a few hundred rpm too early, this is worth a couple tenths in the 1/4. the other problem is that you only have a distinct position for 1st gear (the "1" position), and the first 3 (the "D" position). in order to keep it in 2nd gear till the perscribed rpm, you have to bring the shifter back to the "1" position, after letting it shift (by moving it from "1" to "D" and then back to "1"). Cause you have to do so much fancy work, its the aod shuffle. now, be careful when you are shifting into 2nd gear that you put it in the "D" position and leave it there long enough that it is completely done, before you bring it back to "1" otherwise it will downshift to 1st and that would be bad. if you ever feel quesy about doing this, just push the shifter forward as far as you can (WITHOUT pushing the button) and it will stop at "OD".
