Which jeeps have Command-Trac?
More commonly, Command-Trac is used to refer to the NP/NV-231 or NP-207 transfer cases introduced along with the Jeep Cherokee (XJ) in 1984. The system offers a chain-driven, aluminum, “shift-on-the-fly” transfer case.
Is Command-Trac limited slip?
In the Wrangler, the Command-Trac system is based on a Dana 30 solid front axle, a choice of automatic or manual transmission, an NV231 (formerly NP231) transfer case, and a Dana 35 rear axle (with a Dana 44 optional over the years). Also optional for the rear axle is a Trac-Loc, which is a limited slip differential.
Is the NP231 transfer case good for Jeep 231?
They were engineered for durability and simplicity of build – both an advantage to the OEM assemblers as well as individuals servicing them. The NP231 transfer case has turned out to surprise us in its strength, gearing, upgradeability and servicability. Most of our customers choose to retain their Jeep 231 with their conversions.
Can a Jeep model 231 be rebuilt without lubricant?
Unless you own a TJ model 231, you will rapidly lose the ATF lubricant from the case if this occurs. The 231 is possibly the simplest of all the Jeep transfer cases to rebuild. Their assembly is intuitive, and parts are easily available and affordable.

When did the Jeep 231 speedometer come out?
Early 231s from 1988 through 1991 featured a conventional mechanical (cable) drive speedometer output. In 1992, Jeep introduced a three-wire, digital square wave Vehicle Speed Sensor (VSS), in the vein of modern automotive systems.
