So I have a 1991 22RE standard transmission truck with a bad motor and I have found a motor from a 1994 22RE auto truck that was rolled. Is the ecu in the 91 going to work on the 94 motor (Being that the 1994 22RE is mated to an auto).

Both of these are 2wd. I will use the parts from the bad 91 to eventually swap into my 1982 4WD so this whole thing is related to 4 wheel drive in some way.

Thanks for the help,

Brett
