I have a 96 Grand Cherokee 4.0 with 180000 miles and  a wrecked 97 Cherokee 4.0 both auto 4x4. Are these the same and will brain  out of 96 work with that motor? Neither are HO motors but one is Grand and other is regular.  What problems might I run into. I think it will work but hoping someone knows so I don't do alot of work for nothing.
Also wondering what else might fit like trans, transfer and axles.
Thanks for any help.
