How hard is it to remove NP231 T-case???

Is this a task for more than one person?

What tools are needed, besides the obvious (wrenches, jacks, etc.)?

Its not hard. An extra hand is helpful just to lower the T-case as it will be above your head. Otherwise, support tranny and remove skid plate. Remove both driveshafts (leave the slip yoke in or drain the oil first)Remove the shifter assembly (3 bolts as I recall) unplug the vacumn switch plug and speedometer cable. Remove the nuts from the approx. 10 studs that hold the tcase to the tranny. Slide aft and lower. No special tools needed other than jack stands and box wrenches (metric)
Good luck and email me if you have any questions.
Good Luck

As long as you don't have any problems with the mounting studs fusing to the trasmission case like mine did, it'll be a easy job.
