The yokes are different 1.5 and 1.6. You can use a tail housing off the AOD and put it on the 4r70w and use the 1.5 yoke.

Most of the stuff form what I understand is the updated stuff in that year. Where can I find that tail shaft mod at?

The splines are the same but the 4R has a larger yoke as you said. I believe an AOD tail housing can be installed and you can use the smaller yoke. Mine is an 01 and 99 should be good. Here is one link to give you an idea. Mine had a plastic bushing laying inside that we determined was used on assembly to slide the drive shaft in.

Trans is mounted. Having drive line shortened. Just have to wire up control module. Getting engine rebuilt. Should be a fun ride when I get this done.

Great article. I sure wish that I had gone with that tranny instead of the AOD. Even though the Lentech valve body makes it far better than stock, the abilty to control it more, seems the way to go.

Well, I had to take my transmission in to have it rebuilt. The guy I bought it from scammed me on it. Oh the joys of craigslist. Should of known better. Oh well. Now I have a freshly rebuilt trans with upgraded components. Going to be fun. Can't wait to see what that first gear is like. Pick it up today.

Re: Installing a 4R70W overdrive transmission in an older or classic Ford.

Cool, eh? Just by making minor adjustments or a flip of a switch (depending on the controller), you can make it shift so hard it will take your teeth out, or so soft it's like Granny's stocker. An AOD-E with upgrades, 4R70W, or 4R75W with the famous "J-mods" outlined by Jerry Wroblewsky (Ford engineer that was part of design and testing) and a good controller - it's so solid and fast they don't even get any handicap for class racing against manual transmissions like autos used to.

Yeah, some stick-shift guys get pretty riled-up when you show them how these autos can be faster and more consistent on the strip than a manual. You simply can't shift any more accurately than a computer. But, if you want to "row" it down the road with the shifter, you can still do that too.

Re: Installing a 4R70W overdrive transmission in an older or classic Ford.

The controllers are pretty cool. I had the shop put in Alto red eagle clutch packs with kolene steels. I am using the US Shift controller. Nice that I can control the shift points. And can flip a switch and have a totally different pattern. I did not do the j mod. I have heard about it though. I have my trans set according to their normal shift pattern and was surprised. I am running a 2500 stall. Normal acceleration it shifts nice and smooth. Get on it at half throttle wow. To the floor hold on. Haven't programed in the aggressive shift pattern yet. Going to be interesting.

Re: Installing a 4R70W overdrive transmission in an older or classic Ford.

Love the article. Thanks. I am putting a 4R70W behind a new mustang 5.0 in a 67 Galaxie. I haven't gotten to the wiring yet, but I was able to use the original crossmember and mount with no modifications. Even the 46 year old bolts screwed right in to the 4R. Now I am trying to figure out how to use the column shifter to select the gear. It looks like I will be able to use most of the original parts and make an adapter plate.

Lokar makes a linkage set up for that.

Let me know how it works. I need to put just the arm on my trans so I can get the detentes to line up on my MegaShifter.

I need to do this in the 67 Galaxie. Why can't I still live in the Twin Cities so you can just build another setup.

xavier296 I might need to hit you up for some pictures. I have a 351 in my '67 so it shouldn't be too different.

Larry did you see the arm I made up? That is what I had to do to get my Hurst shifter to match up. A little trial and error but not too bad.
