maybe someone can fill in the blanks for me. i want to put in an aod in my 69.5 but from what i gather the trans tunnel is to small,is that true? i figure if i can get one in the trans tunnel i should get one from a 92-93 e or f 150.i will be doing a shift kit,extra clutches and such.should thids hold up to about 425hp with an additional 100 shot of nitrous?the nitrous would only be at the track.
my70mav, You will need to install the non-lock-up converter kit and a one piece input at you HP and use of Nitrous or things are going to break. You need to build an AOD that will withstand 625 to 650 HP in order to be capable of handling the 100 HP kick of the nitrous. You should use, in addition to what you mention in your post, the mechanical diode one-way clutch and the A+ or A++ OD servo. While I don't recommend Kevar and carbon friction material for the street I do think you will need them for track use. You will also need about 60000 gross weight rated cooler for the application to make it live a respectable life on the street. I would recommend Mercon V fluid no matter what friction material is used. Prospective problems are twisted steel drums, broken one-way clutches, and broken input shafts. A good 3000 RPM minimum stall will also help keep your AOD alive.
how about fitting one in the trans tunnel? i plan to use the car about 90% off the time.why cant i use a lockup converter? what is the mechanical diode your talking about?
The trans tunnel will have to be "expanded". The preferred method is to cut and weld but sometimes you can get away with just using a big hammer. The amount of power you are producing and the nitrous will break the weak input shafts unless you use the one-piece shaft that is used with the non-lock-up converter. The mechanical diode replaces the weak roller one-way clutch. Yhey are slightly stronger than the 14 roller clutch. The 14 roller clutch has been known to break without the addition of power adders.
would it be simpler and cheaper to build a c4 and just trailer the car to the track? i know i'am beating a long dead horse but i know very little about about ford transmissions and i want to build it myself.
Why would you want to trailer it to the track? A C4 built properly will work fine in most situations. If you are running a low rear gear then your engine should be up to the trip at 4000 rpm.
i have 4.11's with a 26 in tire and the track is just over 100 miles each way,hence my desire for an aod but i dont want it to blow up all the time.
