Serious question about 1991 mustang GT AOD transmission
Sorry if this is a kinda dumb question but im stock between a T-5 swap and rebuilding my AOD transmission... My question is ive seen alot of automatic drag mustang but they were shifting the cars like they were 5 or 6 speeds.......does it have something to do with the valve bodys in the transmission? Ive seen so many C4 trannys that were shifted like clutch cars.. can someone explain this concept to me?

the concept is, they gear there auto trans the way they want it to shift, many times the are only 3 speed's on a track car, with an auto there is almost no loss of power in between gears and you can go directly from gear to gear, which is more consistant for drag cars. but stock a manual has more torque in starting gears, if you car isnt really mod'd id go with a manual is more fun anyways =D, conversion arent fun tho...

A ratchet shifter just shifts the tranny into the next gear. You push it up and then push it up again, it wont make the transmission shift any different.
I had my AOD rebuilt and put the 4r70w gears in it, I also had a shift kit installed. I hope to someday go with a converter that's around 3000 stall, and maybe a fully manual valve body.
I would like a 5pd, and told myself I wouldn't get a car without one, but I got a great deal on this car and it had the AOD so I figured I'd give it a try.

Ha same here...i know what you mean... i think im just going to go with a ratchet shifter... i mean i just had a shift kit put on it do i have to do any valve body work to be safe with the ratchet shifter?... is there one made just for our cars or do i just need to pick up a b&m or something?

save yorself some money, stock aod with shift kits dont last, even behind a mild modded motor, i went through 4, now i have a tsi pro street aod, fully manual at wot, and it was cheap...lasted me 7 years so far, you will need to cough up for a precision industries converter though, trans cost me like 1500 back then, and a stallion verter runs 6-8 hundred bucks
With a few mods, like a performance valve body(shift kits may be cheaper, but no screwin around with drills), and maybe a new servo or two, and your AOD will bang en out fast and hard.

+1 I agree, and with the right valve body you can drive your car like a stick like you stole it. Although its more wear and tear, with the right config, you can drive your aod like a stick. I told my self I wouldnt get an AOD pony but after I did and rebuilt it with a good valve body I love it because you can go auto or drive it like a stick.
NOTE: NOT TRIPTRONIC
