The new F150 (04-08) 5.4L uses the 4R75E. The older truck uses the 4R70E. There isn't a huge change between them other than build strength. Gear ratios are about the same. Nobody makes a production after market converter for the new tranny, I had one custom built. Now, if you are sure you have the older one, then look at TCI, they make a few for the older tranny.
You got a 4R75E tranny ? I got a Turbo 06 F150 with a 4R70E do you know of a Converter for it trying to find 1 while I got my motor pulled to swap to a built 4.6L
do what this guy did. install a lightning spec E4OD aka 4r100. the only thing, he didnt mention is wiring and controlling the e40d, a stock 4.6l computer cannot run that tranny, also the 4R70E doesnt have as many input/output wires going to it, so you will need a tranny harness out of a 5.4l powered truck.... easiest way is to get a stand alone controller for the E4OD
I am getting the heads ported to get about 30% more airflow and a custom camshaft grind from Comp Cams. I will get the biggest lift, and most duration I can do on this motor, that will still have some good low end tq. I will have to use new beehive springs and phaser limiters. This will give me power to about 6700 RPM. Fastlane told me I should gain about 60 rwhp and rwtq. So that is about 340 rwhp and 400 rwtq. But with huge RPM gain too. Then I will do a supercharger!
That video was with the NSR cams. I just swapped the cams with 222/228 with 0.540 lift, beehive springs, cam phaser limiters, and ported the heads. I am waiting for an adapter plate to be made, so I can swap my intake manifold with that one on the 4.6 3v. I am only at 301 rwhp currently. I don't have enough intake flow past 5000 rpm. As soon as I get this installed, I should see another 40 rwhp. So that's around 340 rwhp, compare that to stock..240 rwhp.
@ashtrey05 dont get comp cams...go to "MHS" they have the best cams for the 2 valve..its not about lift on the 2 valve pi or npi it about duration and a LAS of 109 to 110 and a centerline of 106/114 or 106/112 in a npi head iam going to get a set of npi cams..duriation- 220/223 lift-525/500 centerline-106/114 lsa-110....i know they are small but i have seen dyno charts that have 30+rwhp with small boltons..exhaust and intake...if you have npi heads you will get alot more torque then pi heads.
Where did you get the custom torque converter from?

Be sure and change the valve springs to allow for the higher RPM, sounds like your on the right track for some real power.
