That article mentions motor oil being OK in the NP231 because it doesn't have a pressurized oil pump. I thought there WAS an oil pump in the TC. Now I'm confused. Or is it just not "high pressure"?Originally Posted by salad
Yep. It was published by Rockland Standard Gear in 2003 on how the NP231 has a habit of evaporating ATF. This is why so many wind up running dry and eventually failing. Pages 5 & 6 of this PDF: http://www.rsgear.com/articles/2003_10.pdf

Ah, so more like a circulation pump than what's in the AW4?
Also, the article mentions a front axle disconnect being helpful to prevent misting of the oil. I'm assuming this is the case with the NP231 since you can shift it to 2 hi and the front axle disconnects, right?
