4.0 pcm swap from aut to man
Hi all first post here
I drive an older cherokee chief (1980) which is converted with a 242 HO from a
1994 cherokee XJ.
My jeep is a 4 speed man an i have a replacement pcm also from a 1994 but
it came from an automatic.
Now the question is it possible to use this one?
I know i read something about this but can not find it anymore.
I tried to search for this but nope

I would suspect it will work fine.

I'm not sure about the year interchangeability but, the auto pcm will work inplace of a manual pcm.
The only difference I found through research is the ignition advance curve, which is nothing worth keeping you from using it.
