4R70W Transmission

How many people have upgraded their AOD to a AODE-4R70W? Experience?

My AOD has a complete 5.4L Econoline 4r70w stack, but a mostly factory valve body.  Swapping an AOD-E or a 4R70W will require the addition of a standalone controller, as well as modification of the shift linkage (unless you have a sport w/floorshift).

I'm aware of this.

A lot of guys run the Baumann, PA, Hughes and others make controllers.  I am more interested in what one has to do to modify their column shift, crossmember, exhaust or anything else.

Ive been running one with baumann for 30k miles. Works awesome.

Tried to get column shift to work with custom cables. Gave up and installed floor shifter. If you have to have column shift, I was gonna try to retrofit an explorer column shift system next. Floor shift is way easier though.

The factory crossmember works slid all the way back. But isnt perfect. I switched to a stifflers crossmember, looks much nicer and fits perfectly.

My exhaust fits fine. Ford shorty headers and summit or jegs h-pipe for auto fox.

My trans is a stock from a 2002 3.8 stang, with a b&m holeshot 2400-stall converter.

Chris,

What is the major issue with the column shift? Routing, obstructions etc??

Aod uses the shift lever facing downward for floor shift and up for column shift.
4r uses lever facing down only, range sensor is above it.

4r column shifts are cable based. Aod are linkage.

So basically 4r lever is in wrong position and shift pattern is reversed for our column shift. You might be able to weld or bolt a lever extension on to make it work, i didnt want to mod trans.

My plan was to retrofit an explorer column shift, since it works perfectly with 4r. However, seemed like a ridiculous project, so i just swapped in a floor shift from 96 mustang. Doesnt look right in console, may switch to an actual thunderbird floor shift or see if i can get bezel to work on mustang shifter.

When I installed the AODE in my '93 Grand Marquis(that I think was actually for a '93 MK VIII 4R70W), I had to swap the lever from the original AODE before the linkage would hook up... Problem is I can't remember exact difference... Other differences were smaller converter so I had to get a different flexplate, and the tail housing used a larger yoke so I swapped one on from the orig trans... That was new Years day '08, AFAIK that trans is still going...
