This is not you simple run of the mill problem. I wish I would have read this thread before I had my trans built! http://www.naxja.org/forum/showthread.php?t=1053970
But I didn't. Hopefully more heads are better, and we can come up with a solution.

Background: I have a 98 XJ that started as a 2wd. I used a donor AW4 from a 96. When I had the transmission rebuilt I had them use the 4wd output shaft and tailhousing from the 96 onto the 98.

Problem: I have now learned about the difference in the 96 OSS vs the 98. A 98 OSS will not fit in the 96 tailhousing. I need to some how get a 4 pulse pre rev output from the rear OSS. (I am getting a CEL p0720)

Options I can think of:
1: Find a junk 98 aw4 and swap the tailhousing enabling the proper OSS. (But is the tone ring/signal generator the same on the 96 output shaft as on the 98)
2: Swap to a 97 TCU
3: Pull my tailhousing and try to machine it to accept the 98 OSS.
4: In a dream world someone will know of a sensor with a 4 ppr output that will fit in my 96 tailhousing.

Please brainstorm with me! any better ideas? Anyone know the miracle OSS part number to solve all my problems?
