[Prerunner1982]

My wife's S-10 Blazer had an NP/NVG 231C with electric engage. The only problem I had was that it would not always engage when it was cold, but I believe it was the front axle disconnect that was causing the problem.

I have an NP231J manual shift in my Jeep Cherokee and they seem to be a strong t-case.

I prefer the manual shift over the electric shift as well... that way I know it is engaged and there is less to go wrong... but then again I also don't like power windows, power locks, power seats... etc.
