Slow 5.0?

dinomite · 07-24-2001, 10:06 AM

There must be somethin wrong, cause even if you were to spin the launch and let the transmission shift itself, that would be at worst a low 16. If you TPS was HORRIBLY off, it might lead to this, if the computer never saw you putting down WOT. When you let the tranny shift itself (leave it in "D") where does it shift if you keep it floored? As you can see from my sig, i have the exact same car as you, with simple mods and run a 15.2@92, so something is obviously wrong. I can also give you my generic AOD shifting response:

you like dancin? you better, cause its time for...The AOD Shuffle!

ok, start by putting your car into 1 (alllll the way down). put your left foot on the brake, and use your right foot to bring the revs to 13-1500, or until the tires spin (takes some practice). when you are ready to go (don't sit like that too long, it will burn up your converter) release the brake and depress the throttle fully, you'll have to practice to find how quickly you can do this. when the revs hit 4800, push the "gear selector lever" up one notch (to the "D" position). the tranny takes about 300 rpm to shift, and once it has fully shifted, and you've waited a second (don't go to early), 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, i call this manuver 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" (at least mine does, it might go all the way to "N", that'd be ok too. just don't press the button when you do that, cause it will go to "R" or "P", then you would be looking for a new tranny).
