ZJ's had a bad problem with cracked valve bodies. New VB is about 100 bucks and easy to swap . this should fix your shifting issues.

4.0s with odb2 don't like to run without a cat. The downstream o2 sensor will keep throwing a code. Also, 4.0s will default lean when an o2 code is sent. So put a cat on it first and see what happens. I put those E3 plugs in my tj and it didn't like them. Autolites are the best.
