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.

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.

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."

"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.

The manual says 2.85 pints of ATF+4 for my 242

Thanks for the info guys....leaning toward the 242.

Any years not compatiable with mine (95 GCL 5.2L 46RH tranny) ?
