Re: TC Swap in mind
Afaik, Selec-Trac is a mechanical or gear system, with no viscous clutch
pack. You can find out for sure if you have an owner's manual. Does
Selec-Trac use a "special" fluid that has to be changed all the time, or
Dexron ATF?
"The chain driven NP242 is a full time transfer case with a 48/52 torque
split front and rear."

http://jeep.avtograd.ru/Cherokee/xfer/index.htm
"Torque split" means that there is a center differential, not a clutch pack.
There are web sites that say it has a clutch pack, but you can't believe
everything you read on the Internet.
