Question on Ford truck automatic trannies

My brother has just informed me that the tranny in his '97 E-250 van (4.2 V6) gave up the ghost. He looked in the local bargain hunter and found somebody selling a tranny from a '94 F-150 (5.0 V8).

I know the 4.2 and 5.0 share a bell housing, but what I need to know is what these trannies may be, and are they interchangeable? I've googled it with no luck. Mitchell OnDemand shows three different transmission possibilities: AOD-E, 4R70W, and E4OD. I think the E4OD isn't likely, as from what I've read that seems like a heavy duty tranny that wouldn't likely be sitting behind a V6 or 302.

I know the AOD-E and 4R70W are closely related, but are they interchangeable as a whole unit? Are they electronically compatible?

'Nuther question: I know the old AOD's could act up when the TV cable was sticking (would not shift right, would downshift early, etc). The weather has been very cold, and I think his cable might be freezing, causing the problems he's described. This, of course, would depend on whether the AOD-E or 4R70W even have TV cables. So do they?

Would that cause TV-cable like symptoms? The transmission is shifting very late and downshifting very easy (giving him engine braking when he slows down as the tranny shifts into first gear). My old Cougar did this because the TV cable linkage on the transmission had seized up - the first time the throttle was floored (translation: The first time I drove it) the cable stayed in the WOT position. I was thinking that maybe ice has caused this to happen with my brother's tranny (I haven't looked at it or driven it yet, I'm going by his description of symptoms)

I have the shop manual (on CD ugh!) for 01 CrownVic/Grand Marquis.

They use the 4R70W. It is electronicaly controled by the PCM (Powertrain Control Module).

The PCM controls shift timing, line pressure and torque converter clutch.

It uses a lot of sensors including some that are also used to control the engine. The TPS for instance. I see no mention of a TV cable.

The door jamb label TR code:
U-4R70W Livonia Transmission
H-4R70W Sharonville Transmission

If it is a 4R70W an OBD II code reader may give a clue to the problem. There are lots of sensors involved.
