hi, i wanna convert my mustang 67 from a C4 to any 4 or 5 speed automatic. the engine is a 347 stroker (based on a 302) we are looking at ~450 HP and +/- 650Nm. do you have any ideas, experiance, inputs, connections etc??
cheers from wien/austria

You can order all the parts from any of the "resto" parts houses such as NPD (National Parts Depot) or Mustangs Unlimited (mustangsunlimited.com catalog online). to do a AOD swap into a 67'. Very roughly...$500 for parts.

I'm not sure how well an AOD holds up to that much horsepower in stock form, so you may want to look into doing some mods to it, to help it last longer. I also remember something about that they wont go into 4th gear at wide open throttle.

[voodoosurfer]

you might try these places for the info you want. they also build the tranny's to perform with that horsepower. I read that a stock AOD wont last very long with anything rated over 250 horse because it has a soft input shaft or something.

folks, thanx for the infos. i will keep you adviced.. at the moment i am searching all the links you posted.
just for your info. at the moment i use a ZF 4HP22 in my mustang. thats a 4 speed automatic with a 1:0,73 fourth gear. i worked well with the standard 289 4V. i am just a bit worried how long it will last with the new engine.....

"Built" AODs are easy to get and will hold up well. Eliminating the lockup makes them much stronger. Contact Art Carr.

AODs are almost a drop in situation. Most of that kit stuff is not needed if you can do a little work yourself.

That ZF will last until you step on the gas of a 347.

? you can make your own crossmember and mount ($120?), everything else you got to buy:flexplate/yoke/shorten-balance drive shaft/ = roughly $400

nah! ain't a drop in cause you gotta' re-work the exhaust...I hate fab'n exhaust!

advice?? OK first make sure it is a "short-rod" 342 (347).

Fabbing the original crossmember is easy.
Flexplate is balanced to 28 or 50 and must match the trans bellhousing diameter.
yoke... easy to get.... not expensive anyway.
drive shaft.... had to shorten mine.
Use the Mustang AOD shifter stuff.

Well, exhaust...... if yours is in the way..... not everyone's is.

why does it have to be a 4 speed with overdrive behind your 450hp motor?

what gears are in it now?

Ok, I'll compromise with xntrik, it's a drop in swap parts project IF your real lucky!

Red,
I did not intend to make this a debate. Only suggestions....

But WE ARE hotrodders, and generally speaking I think that many of us don't have to spend gazillions on "kits" to make our stuff work. The spirit of hotrodding used to be.... build it yourself. Of course in this new millenium the trend seems to be...... install the expensive-custom-made-powder-coated stuff yourself, unless there's a ball game on TV, then hire a custom shop to do it for you..

[red65mustang]

xntrik, no debate,I agree, I was waving a yellow flag cause he didn't give much for details, my rule #1= assume nothing
ha! I should change my board name to: red-"custom mount"-mustang, I fab everything from mufflers to fan shrouds...my tombstone will read "it's a custom mount"

Mine will probably say "His life was hotrods."

@ red

red, well i ride this pony for almost 18 years by now. did a full restoration within the last three years and use it as a day to day car. (hate this modern electronic toy cars....) the only thing that bothers me is the high rpm while cruising from a to b (we got a limit of 85mph, they tolerate 95). a long rear end is no opption as i want launch the old mustang from the robot (traffic light)
i want a trany with 4 or 5 speeds NO overdrive. four should do, actually. i dont like the overdrive concept - a three speed gearbox with an fourth *something* controlled by the high tide on the uk coast - at all!! while i was reading all the postings i got the impression other guys think the same way specially with their expereances.

ps.: sorry about my english, spelling etc....

AODs can be made to live behind serious
power.

And here's how to swap one in
http://www.mustangmonthly.com/howto/33598/
http://www.windsor-fox.com/

You DO need to replace the center/inner input
shaft (for 3rd & OD) with a hardened shaft -
they're about $170. Or you can eliminate
lockup but then you have to buy a different
turbine input shaft (without the little center input one)
and a non-lockup converter (or if you've got a lockup,
just don't install the shaft)


For an all around better trans, especially
allowing better control of the shifting,

And here's how to swap one of those in
http://www.blueriver.net/~finite/project_od.htm

If you can find a decent used 4R70W, you can
keep the costs pretty similar. Or use the guts
to swap into an AOD as outlined in the above
article.
