are all transmissions the same?

i've been doing some reading, finding that the 4r70 has some weak points.. and when a rebuild is required, upgraded parts are available.
my question. will different year model transmissions interchange or will i have mechanical and or electrical differences to deal with.
i have a 96 and a 98 out of mark 8's… the 96 has a leak at the shifter shaft and will need fixed. the 98 came out of my parts car… i could have that one rebuilt... then just do a exchange if they are the same. that way i wouldn't have to wait for a rebuild or get a unknown exchange unit… the wiring and shop manuals seem to be the same for both years...

also i've been looking to replace the ignition coil packs. are they interchangeable with say a crown vic with the same ign system… lincoln parts are always over priced… almost as bad as a boat...
bear with me with my questions, i have been away from automotive pursuits for about 30 years and things have changed a lot…
some for the good, some not so good...
but challenging for me to catch up on new tech.

thanks for any assistance provided…
