Ok, I have asked this on several different jeep forums with no answer. Here is the deal:I have a 2002 NV231 transfer case in this wrangler with a 21 spline input shaft. This 23 spline input is for sale http://www.ebay.com/itm/180984577476?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649I will be mating the transfer to a NV3550 trans with a 23 spline output shaft. There are 4 different 23 spline input shafts for this transfer case, 2 different lengths and 2 different bearings...........What I need to know is if any of you know which input that is 23 spline will work with my parts? If any could help that would be great. I have local yards with jeep stuff so I think I could find one cheap and easy, or go with the ebay one that is pulled, but I just need to know what will work or not.EDIT: Just found this, still am unsure of what I could get, but at least I have the differences laid out plainly. I should be able to do it once I pull the unit from the jeep now...at least. From what I gather it will be a late 23 spline with the narrow bearing and long input. Still if anyone knows what is up and could tell me I would take that.http://www.novak-adapt.com/knowledge/np_nvg_input_gears.htm

I've been doing a lot of research, and this is what I've come up with:1.) The Jeep Liberties came with NV1500 (between 2003 and 2004 with the 2.4L motors).2.) The NV1500 shares the same case pattern as the NV3500/NV3550.3.) The NV3500 shares the same case pattern as the Toyota R-series transmissions.4.) The Toyota R151F bellhousing has the 22RE pattern on the front with NV3500 pattern on rear.5.) Volkswagen TDI/TD to 22RE style transmissions adapters are common and relatively cheap (Rocky-Road, ACME Adapters).Result: The ability to bolt on a Volksagen TDI/TD into a Jeep Liberty using:TDI/TD engine | Common Adapter | R151F bellhousing | NV1500 transAnyone see any fault in my logic?*********************I ripped that off another forum and it was interesting to find. This is helping me as I have the NV3550 and now know that the Acme cheap adapter will work for what I need if I don't want to build it myself.http://www.acmeadapters.com/store_engine.php
On the outside the nv3550 is identical to the ax15. I am just looking at getting this mess bolted together.And you are comparing the NV 3500 to the NV 3550. The 3500 came in trucks, the 3550 was something weird that jeep did.
I know...The outside ex: bolt pattern, case shape, is the same. You couldn't interchange gears and shafts. I could care less. But if you wanted to physically bolt one onto the same engine I am saying it is possible, I am not saying that they are the same trans. I have done tons of research and it all ends up the same. The Jeep that has an AX 15 you can bolt an NV3550 to with no mods. So if it is like you say an AX15 is identical to a 151 then I will be able to use the acme 151 adapter for the NV3550.
I have a 92 xj as well and have a 1.9 TDI that's almost ready to bolt in.There is many companies out there that are making TDI swaps a lot more easy and cost efficient.I was able to get my ECU Flashed HP Boost/security eliminated along with a engine management harness that's down to 5 wires to hook up and the motor is running.As far as mating the engine to the trans this wasn't that hard. 1/2" Alum. adaptor plate bolted to the engine with the bell housing pattern on the plate.I'm using an AX15 5speed along with the stock clutch and flywheel. The flywheel is machined to the TDI offset crank bolt pattern. Along with the 4.0 starter.I haven't figured out What I'm going to do about the drive by wire for the throttle or the motor mounts, and of course cooling
