K2ZJ
Explorer
Read, he DOES NOT have a 231 or a 249, in 96 the 4.0 ZJ only came with a 242.
Limiteds come with the 249.
"4WD systems included Command-Trac, a part-time unit offering temporary 4-wheel assistance; Command-Trac was dropped from lineup in conjunction with the SE trim in 1996. Select-Trac had the option of either full-time or part-time operation; Both shift-on-the-fly Command-Trac and Select-Trac were already available for the Cherokee XJ lineup, and were adopted to the ZJ platform. Exclusive to the Grand Cherokee was the introduction of Quadra-Trac having all-time four-wheel assistance only, this was standard on all Limited and specialty trims and optional for Laredo models alike. Two-wheel-drive models were sold though only for "Laredo" trims in late 1993, it wasn't until 1994 when 2WD was available for Limited; and in 1997 5.2 L V8 engines were sold along with 2WD."
So, my 231 info is off, but he can have the 249 or 242.
