1st gear for hours at a time ok?

Like many of you, I use my Jeep almost exclusively for camping, towing, and trail driving. Often times while on the trails I drop the trans into 1st gear and leave it there while creeping up or down rougher terrain, sometimes for better than an hour at a time. I've not experienced any trouble so far but I know that doing this on some transmissions can stick a valve and cause shifting issues. Any problems doing this with the 46RH?

All I can see worrying about is keeping it cool . Maybe Tex can be more specific with his answer and change my mind , I've done it lots without any issue

I always keep an eye on temps, and my ZJ is equipped with the factory trans cooler (not heat-proof but it helps.) It never gets hot when creeping on the trails. I just wish I had a crawler gear because I do sometimes worry about the brakes on the long slow downhills.

Specific, the zj is designed to be shifted into 4lo and into 1st and left there for long periods of trail riding, rock crawling and mud digging.

The problem is that most zj drivers have never shifted their transfer cases.

Mine is a NP249, I have yet to encounter a situation where I needed 4lo (which either means the 249 is THAT awesome or I only do sissy trails). Anyhow, the linkage for the 4lo is a mess, the cross-pin keeps falling out and I haven't yet rigged up a good fix for it. Thats next on the list after I get this damn right front suspension clunking thing figured out.

BTW, will dropping the transfer case into 4lo be more of a "crawler gear"?

Yes, low speed and a lot more torque at low RPM's. It flows all of the oils and fluids at maximum to keep things cooler.

Cool. Guess I better get busy and fix the damn linkage issue so I can actually use my 4lo.

Sir, that's the best thing I've heard in the last 3 mins.
