are there any modern 6 or even 5 speed auto's that will mate up to a 68 289?? I know the AOD fits pretty readily, but can i get 1-2 more gears??
thanks guys

The AODE in my daily driver is has 3 regular gears and an over drive. I wouldn't say it behaves at all like there are 5 total gears.
I'm not sure if the 4.0 block in the new 05+ Mustangs has the same bolt patern as the 3.8 engine. The 3.8 and the 5.0 share the same bolt paterns for the bellhousing so if you could find out if they interchange you could get one of the newer 05+ transmission. I think they are 5 speed autos if I'm not mistaken.

I thought the new 5spd auto's were actually 4spds
From what I can recall it has 4 forward gears, the 4th being overdrive. it has the same gear twice if that makes sense. One is for acceleration and one is for when you slam on the gas.
Its like when your cruising it will go up
1 2 3 4OD
and if you're in 4OD and slam the gas it will go down into a different gear that is made for the hard shifting or something. I thought I remember reading about that.
Then again I could be totally retarded because It's 8AM and I can't think straight.

P.S. I think they can still call it a 5spd because it has 5 gears in it, although two of them are geared the same.
I don't understand how 2 gears can feel different if they have the same ratio. Does make sense to me. Maybe its just the torque converter. You should stop by a Ford dealership and test drive the new Mustang with the supposed 5 speed auto to see what the deal is. Ask a salesman to explain where the 5th gear comes from. Hopefully you get a guy who knows what the hell he is talking about.... or you could go talk to a service tech in the back after you test drive it.

If the difference was the converter, they would have called the AOD and E4OD 5 speeds as well. I doubt they only have 4 speeds...
When the old ODs get into 4, and driving steadies, the converter locks up, giving the feel of a 5th gear.
In a sense, it is, because the rpms drop 500-1000 rpm, just as different gearing would do. But they still never called it a 5 speed.

ill try to stear things back on track here....but how about 90's 150's?? as far as the 4.6 block, did for stay pretty consistent through the years??

The 5spd auto in my 96 explorer used the o.d. gear twice to gain an extra ratio. I think it went like this: 1st, 1st + o.d., 2nd, 3rd and 3rd + o.d. This gives 5 unique ratios. The idea was to keep the engine in it's power band while accelerating. I don't know if the 5spd auto in the new mustangs works the same way.
I'm geussing these all would require some sort of CPU though...or are they mechanical?? in order to fit them in a classics stang I's have to add some stuff..
so what am i looking at for some years here?? i geuss I;m not all that familiar with them, so give me some insight!

Probably cheaper and easier to use a 3 speed (or even AOD) with a Gear Vendor OD.
The 'cheap' version is totally manual, so you have an extra gear up top, but have to shift manually to make OD for the other gears.
There is a spendy version that is electronic controlled and shifts the OD along with the tranny's regular shifting, and makes a 3 speed into a 6 speed, or 4 speed into an 8 speed.
Both versions are expensive, but after you find a 6 speed auto, adapt it, and hack a computer to run it, you are up there too.

You don't need to hack any computer, you just need a Baumenator or what ever it is called. They are stand alone AODE ECUs that this guy sells. They ain't cheap but they don't kill you either.
