I have a 1990 685 Case IH. 4X4 tractor. It has high, low, and reverse on 1 shifter, and it has 4 speed gears on the other shifter. It jumps out of reverse. What could cause this and how much would it cost to repair it? Thanks, Steve

The Borg Warner (BW) model 4493/4494 NR4 transfer case is a 2-speed, full-time 4WD, transfer case. The transfer case has an external planetary type differential, which has 2 different sets of pinion gears. The planetary differential provides a 40/60 torque split front/rear full-time. This means the front and rear propeller shafts are constantly being driven for maximum traction in all conditions. A high/low planetary carrier assembly provides the high and low ranges, which is a 6-pinion gear, sun gear, and annulus gear arrangement, giving a 2.64 low range reduction ratio in the BW 4493 and a 4:1 ratio in the BW 4494.

manual controls are very reliable, like in or out.If the shifter is hard moving? use some oil.Gear clash grinding first to reverse.counter shaft nose.If there is no high or low 4x4 Good luck.

sounds like it is not going all the way into gear in the transfer case ck the adjustment, is this electronic shift , ck for dirty connections ,

Motor and trans mounts worn or the body mounts worn letting it flex and nock it out of of Gear,,,if the truck is lifted/ or not you will need to in large the hole where the transfer case shifter comes the the floor,,,

Depends, do you have 4 wheel drive? If so you can just use 4 wheel high, or if things get really slippery, use 4 wheel low and go slow, both in the drive position on the transmission shifter.

If 2wd, just use drive and go slow, again, if it gets slippery out, you can shift down in gears to go slower and to keep your speed slow.

If you're talking about snow and ice on just streets, then stick with 4 wheel high with 4x4, or "drive" in 2wd. You typically don't want to switch to 3,2, or 1st gear at highway speeds.

If you're playing in the snow, just use 4x4 high until you get stuck, then switch to 4 low to get out.

The only time I switch gears with the transmission (from drive to 3,2, or 1) is when I want to go really slow and keep it there. However, when I "play" in the snow, it's Drive only.

Does this answer your question? If not, let me know! Thanks

u might need to get on ebay and try to find a new switch

have truck running,,put shifter in neutral,,shift into high lock 4x4,then put truck into gear,,u can shift from high lock to high gear,,from two wheel to four wheel,,in high only,,if u want to shift transfer case in low,,u have to put truck in ,,neutral,,first,,

You can try several things. You can stop the vehicle as if you are going into low range and shift the high range 2h, 4h, etc.. Ford advertises the Electric button type as "shift on the fly" but does not say the gears are synchronized to do that with manual engagement.

Change the lube this time to see if the lube is Milky. There have been floods, otherwise the case is sealed whether you park it or drive it. You still could have rust on the shift linkage. You need to move the linkage as you spray it. Then the offbeat chance something was bent from offroading. A Salvage Yard is a wonderful place to learn how a car is built. You may see their part looks different than yours.

If you have it in 4 LOW, you would never need overdrive. Overdrive is a road high gear that you would use only in 4 HIGH (or 4H) on your shifter. 4L (or 4 Low) would only be used in a very slow speed hill climb. You would NEVER use 4 Low on the road.

I have a 1974 case backhoe 580 it will not move in any gear.
