yj to tj transfercase swap

    will there be issues in changing out a np231 out of an 89 yj 6 cyl. to a 2000tj np231 ( speedo cable and or gears ) with complete drive train swap. tranny,transfercase,sye, and drive shaft.

    I dont think there will be any issues, just use the sensors and all from the new jeep.

    Check the transfer case input shaft spline count
    Some early YJ's and xj's used a 21 spline while the newer ones use 23 spline
