Are the 3-speed and 4-speed transmissions from a 1994 Caravan with the
3.0 engine in any way interchangeable? I ask because the 3-speed in my
brothers Caravan is shot and someone offered me a working 4-speed also
from 94' Caravan with a 3.0 engine. I was thinking since it is the
same van and same engine somehow both transmissions must bolt on the
same way. Or is there a lot more involved in this than I am thinking
of? Thanks in advance.

Sara,
I dont know. I suspect that if the 3 and 4 fit this engine in general, then
either would probably bolt up, BUT the PCM might have to be changed
as well.

These things are sometimes just not as simple as they once were.

Right... It is like installing something new on your computer. You connect
it, then need to add/change the "software" to make it work with the rest of
the system.

And in the case of automobiles, if it was not an original factory option,
that software is not going to exist.
