was offered a 97 v6 t5 cheap. engine is blown and high milage. was trying to figure out what would be needed to swap in newer 01-03 engine and auto transmission. I know fuel rails will be needed. and to swap the sensors out and reuse the 97's engine harness. what about the trans tho? never messed with electronic controlled ones just aod's.
trans and engine swap into 97

an automatic PCM would be needed, and a Dallas Extended Range Speed Cal since 99-04 use different speed sensors.
since a new PCM would be needed, this raises issues with PATS. it would need a tune to turn PATS off or towed to a FORD dealership to have it reprogrammed. i suggest the tune, becasue the engine will need a retune to run the larger 99-04 injectors.
01-04 V6's have Intake Manifold Runner Controls (IMRC's), the 97 computer will not run these and they need removed from the Lower intake manifold. just take them out and fill the holes with JB Weld.
the driveshaft yoke needs to be changed to accept the Auto trans.
other than some minor rewiring, i think that covers the major stuff

you can swap the tailshaft from a 96-98 v6 auto trans for the sensor. not sure about the Non Pats ecu, i'd send an email to VMPtuning and see if they have any insight on that. i would assume you would need to find one from a 1996 Automatic V6 without PATS.
im pretty sure there is a write up on swapping tailshafts, i need to get going, i'll try and post it up later if i can find it
So what year was pats introduced? So far I'm looking at
Modified fuel rails
Auto ECM
Trans Harness
96-98 Tailshaft
Delete IMRC's or use 99-00 Upper intake
Auto driveshaft yoke
Shifter assembly
Would'nt I have to reuse the 97's fuel injectors? I thought 01-04 ones are different. And don't I have to splice the connector for the IAC into the 97 harness?

PATS was in all cars in 97, and i believe it was optional on 96 cars
that list looks fine except you would need a 99-00 lower intake manifold, not the upper. the uppers are the same for all 99-04. and dont forget the pedals.
if you use 97 injectors you'll be fine. but getting an Handheld tuner like a SCT X-cal would solve both the possible PATS problem and would allow you to use the injectors from the newer engine.
not sure about the IAC connector, but i imagine if they are different, you would need to splice the connector into your old harness. i'll see if i can dig up anymore info on that
My bad, I meant lower. Had typed lower and upper guess i deleted wrong. Far as the pedals, would it really matter? I know the clutch pedal would be useless but the accelerator and brake would still work right? Or is there some kind of trans lock switch on the auto's brake pedal?

also if it is in your budget get the windstar. I preach that upper intake for a reason.

there is a lock out switch that keep it from being shifted out of park without the brake pedal pressed. not sure if the pedal connectors are the same or not though

npi 2v's are slower than split ports. it's harder to swap a 4v into the v6's than you think.

I frankly dont see what's so difficult, it's a direct bolt in affair. v6s and cobras are made on the same assembly line.

they dont need a new K-member, and you have to change the from a Vacuum Brake booster to the V8's Hydroboost
