5.3/4L60e/NP261 Swap into my '89 XJ?
I am considering doing this within the next year. In order to meet all the California SMOG ref requirements I have to run the same transmission and transfer case from the engine donor vehicle (yes, they'll check).
So anyone done this swap using the GM/NP261 transfer case mated to a 4L60e transmission?
Thanks guys!!

havent done that one. but let me know how it goes cause im a gm heavy line mechanic and know that drivetrain in and out. i was actually thinking of a similar swap. let me know if you have any questions on how to work on the drivetrain itself.

double check your inspection laws before you do this-- I know ny requires that you can only put a motor in a car that was offered by the manufacturer the year your car was purchased-- for the xj,that means just a 4.0... NY typically follows CA.. so....
not trying to talk you out of it, just make sure you check.

Okay guys, I guess I should of stated earlier that I already know the swap is legal, I am just wondering about driveline stuff.
Thanks for the replies though.

This XJ is my wife's daily-driver. It'll get a 2" lift before too long (with new rear leafs to correct any sag through the years) and maybe a set of A/T 31x9.5x15's on the stock aluminum rims. At most it'll see some weekend sand dunes and an occasional trail, nothing too serious.
The full size '87 and earlier GM/NP transfer cases are passenger drop. All the full size '88 to present are driver side drop.

I'll be honest, I am prob at least a year away from the physical swap in my XJ. I'll start collecting parts before then, but I am usually slow with my own projects because I wait for the uber good deals to come along before spending any cash (no whipping out the ol' credit card either). But when the time comes, I welcome the help since I've never done a LSx swap into a XJ.
I do LSx swaps all the time for customers, usually you'll find 2-3 LSx motors and transmissions in my place at any given time.
Right now I have 3 LSx/4L60e swaps lined up for different customers, the current being a 5.3/4L60e into a '67 Camaro. The motor is getting a cam/springs/pushrod/oil pan swap prior to installation and the PCM/harness is being reworked for stand-alone operation. I am just waiting on the customer to get his cam from Summit before I start. After all the engine work is completed, I'll have the customer bring me the car and the swap done in the car and running within a weekend.
If you like, you are more than welcome to come and check it out.
