So drove my truck today after having misfire issues. Felt like it was in 4 high. But when I try to shift into 2hi its got like no power and feels like its gonna pop out of gear.
NP231 t-case.... Hasn't been changed in the past has it? Shift pattern changed on the newer ones......
Tag says 231 D, I tried shifting it into 2wd multiple times with no success. I feel like its just not engaging enough ?
But when I am in what's supposed to be 2wd and try and move in moves a little and then there's just no power and revs up with it trying to grab. I don't know how to explain it other then it not engaging and slipping or something but is fine in 4hi

From here, that has the aroma of vacuum leak. There's quite a lot of vacuum manifold connected to that circuit from topside down to the case and forward to the CAD. You might consider taking the hand vacuum pump to the thing to do leakdown tests of the lines.
