Is there a part time transfer case for the Jeep Grand Cherokee?
The Jeep Grand Cherokee/Commander line no longer offers a part-time transfer case option. The reason behind this was its poor sales along with an improved Selec-Trac.
How does the 4 wheel drive system work in a Jeep Grand Cherokee?
In this way, the transfer case works almost identically to the NV247 transfer case used in the Quadra-Trac II system in 1999 to 2004 WJ Jeep Grand Cherokees. In 4WD Low mode, the clutch pack is locked and power flows through a 2.72:1 planetary gear set for higher torque at lower speeds.
What kind of transmission does a Jeep Grand Cherokee have?
There are reports of a modified version known as NP-231J HD which was supposedly (SP) a “heavy duty” version for the Jeep Grand Cherokee with V8 engines. The NP/NV-231 case is a chain-driven unit that takes 21- or 23-spline input shafts. The 23-spline was for the AX-15 transmission, and the 21-spline was used for the AX-5 and BA 10/5 transmissions.

Very often, this will solve the problem. But Jeep Grand Cherokees seem especially prone to more serious transmission problems, and some owners are quite vexed at their inability to determine the causes.
What kind of transfer case does a Jeep Grand Cherokee use?
In 1993 Jeep re-introduced Quadra-Trac, this time on the Jeep Grand Cherokee using the NP249 transfer case. Like the NP219, this transfer case utilizes a center differential with a viscous coupler to provide smooth and efficient four-wheel drive operation on all surfaces.

When did Jeep start using the Command Trac transfer case?
The Command-Trac HD transfer case was used in 6-speed Liberty KJ’s from 2005 to 2007. Although sometimes referred to as the “NV (NP)231HD,” the transfer cases are actually the 241 series used in full-sized trucks from other makers (241D or 241C). The Jeep version is labelled “NV (NP)241J.”
