AW4 Transmission Swap

I am prepping and gathering parts to swap out the TF727 for an AW4. The plan is to keep the NP229 and column shifter.

Here's the parts list so far....

-AW4 transmission - 23 spline
-AW4 harness, attached to transmission
-Cherokee underhood main harness (Has wiring to TCU)
-TCU
-TPS sensor
-AW4 starter
-AW4 flywheel
-Spacer between NP229 and AW4
-various lines and fittings for transmission cooler
-transmission cooler

So far, I have the TCU, AW4 and both harnesses.

For the spacer, I was considering this. Is this what I need?
Advanced Adapters Part 50-8603

I would appreciate any tips or advice.

Is your gearing going to work well with OD?

3.31 & stock wheels and tires. According to some other threads, that should be ok, and @ 65 mph rpms will be between 1800 rpm-2100rpm.

If I remember right, my '98 XJ had 3.55's with that AW4. I lost a bit of grunt when I went to 31's. That was with the 4.0 liter motor.

Pretty sure what you need is a Dana 300 clocking ring if you have passenger's drop,
flip ring if you have driver's.
I've got a flip ring I'd let go for cheap + shipping (I needed the clocking ring. Whoops)
The NP229 is standard six-bolt NV / NP mounting, right?

The pattern is the same, but I'm getting conflicting info. I think I need the clocking ring. I think a flip ring would make my np229 a passenger drop... which I don't want. Can someone confirm that?

I'm planning on the AW4 swap in my '90 this winter as well. I thought the NP229 bolted to the AW4 without an adapter.

From my reading, there's a gap when you insert the shaft of about an inch. A 7/8 thick ring will work.

Yeah i did more research after posting that. Seems a spare is needed. Should be pretty simple to make hopefully.

I have a '95 AW4 and a '97 TCU.

You'll need 7/8" spacer and longer mounting studs because the earlier Tcase input shaft sticks out further than the later NV231/241
