I have a 99 and put in a SYE years ago. Had never done it before. The only problem I had was getting the oil pickup tube and screen filter back into the case correctly. Just take your time and pay attention to how it comes apart. It's really not that hard. Hope your planning on taking it out of the jeep. I did it on the bench.
