Selec Trac Transfer Case. If any of the requirements to select a new transfer case position have not been met the transfer case will not shift the indicator light for the previous position will remain on and the newly selected position indicator. You should have the 242 tranfer case if it is a selec trac and these do not have any sort of clutch pack in them.

An n neutral position to disengage the axles from the power train part time four wheel drive in lo range. The shifter has modes 2wd 4wd hi part time 4wd hi full time n 4wd low. The end with the least traction will get the most torque.
The only difference is that the np228 does not have a viscous type limited slip coupling.
The only difference is that the np228 does not have a viscous type limited slip coupling. The np228 selec trac transfer case is closely related to the np229. Ive heard others question the durability of the selec trac system but its standard on the 392 so i feel like it must be stout. And in the case of 4x4s each of the four wheels need to be powered.
