No 4 LOW
I was pulling out some trees over the weekend, and when I tried to shift into 4L, I couldn't. What could be the reason for that? Bent linkage, lack of lubrication, operator error, ... ?
4 low did work fine when I bought the car ( '00 ) and maybe even a couple of years ago, but other than trying it out and driving a few feet, I never really used it.
Car has AT, manual shifter and manual hubs. The exact symptom is that I can't put it into neutral from 4H. (2H - 4H - N - 4L)
TIA

Oh, well ok... I know the manual case that I just put into my 93 was kinda sticky the first few times I went through the shift pattern. But after a few times and some "lamphouse lube" everything is moving well.

You have to have the tranny in N too. Don't be hesitant because it'll grind just a little sometimes cause things are turning in there. Grab that stick, with the tranny in N, pull it back firmly and it should engage.
Have you ever had the oil changed in the t-case? If you haven't it takes about 1.5L or pints of ATF. When you pull the drain plug, a large amount of metal shavings coming out the hole would explain why it doesn't want to shift....

It won't go into N or 4L while the tranny is in park. You have to be in neutral. This threw me for a loop for a while. I still don't understand the difference. There's no tension on the output shaft, right? So why the t-case care?

Your input is splined into a gear that goes into the planetary. In high the shift collar goes forward and engages these splines and powers the front as well as the rear. In low the shift collar has to move further and engages the gears on the planetary. When the shift collar is trying to engage with the planetary it's beveled teeth have to mesh on the outside with the square cut teeth of the plantery - with the input shaft (tranny) in nuetral it merely pushes (spins) the planetary and input shaft a little to align. If the input / planetary won't spin; the beveled teeth of the shift collar will just jam against the planetary gears and stop. That is why the tranny must be in Neutral when shifting to Lo.
I've had to rebuild the BW1356 in my 89 a couple times - LOL
Just a note on that - make sure to use an oil pump supply hose that is GUARANTEED not to shrink while immersed in ATF for its lifetime!!! Using a type that shrinks = Not Funny!

Thanks for the replies. I just went out and tried it -- worked at the first try, so it was operator error, that's sure, though I still don't know how it happened because I think I also tried to shift when it was in neutral.... 
maybe I didn't pull it slightly toward me. Oh well, all is well now.
