TC Swap in mind
Posted earlier about the viscous coupler problem in my NP249J...thanks for
all the info...
But I'm thinking of changing over to the NP231 or NP242. I need to know
which is better( if at all) and what years are compatiable with mine. It
would be used for light off roading and a lot of highway driving.
Here are the specs.
1995 GCL 5.2L 46RH NP249 TC
What years will bolt into my ride? (I know I have to swap the input shafts
and the selectors).
TIA,
T

Re: TC Swap in mind
The full time four wheel drive mode of Selec-Trac would be useful for nasty
weather highway driving. From the reports, it is as robust as the NP231 for
off-road use, although it does have more moving parts. (More moving parts =
more potential points of failure.) From what you are saying about amount of
off road versus on road use, you want the NP242.

Re: TC Swap in mind
The 242 has more vicous clutch packs, the 231 does not. 231 is generally
cheaper, but the 242's full time 4wd could be nice.

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://www.jeeptech.com/wiki/index.p...Factory/NP-242
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.
