Re: Transfer Case question / 2000 Jeep Grand Cherokee
 

there is a small round tag on the bac of the t case near the drain plug and fill
plugs that must be looked at if the tag has 231 or 242 on it dexron 3 is the
fluid. if not then the mopar fluid must be used the other t case numbers are 249
and 247
247 is the one that can get messed up using the wrong fluid
the viscous coupler will not slip as designed and result in binding in corners and
parking lot maneuvers

Re: Transfer Case question / 2000 Jeep Grand Cherokee
 

Lon, I could be wrong on the JGC's t-case as I really thought it was a
chain driven t-case as is used in most Jeeps. Maybe the Quadratrac or
Quadradrive t-cases have a clutch but I thought they used a differential
to provide for their full-time abilities.
