Question
I have a 1992 jimmy. It has a button you push to put it in 4 high or 4 low. We put it in 4 low and get get it back to two wheel driving. Can you help?

Answer
Dana,

Is it going into high range when you select 2-Wheel drive, or is it actually staying in low range?

Check your user's manual.  Some vehicles have a method of shifting from low range back to high range or 2-Wheel drive such as slowing down to 2 miles per hour or slower, then putting the transmission into neutral before shifting from high to low, or back from low to high.

If you don't have a user's manual, I would purchase one at your local dealer.

If this doesn't work, you may have to have it checked out at a reputable transmission shop, preferably one that specializes in 4-wheel drives.  You may have a broken wire, bad switch, or a bad vacuum line at the transfer case.

Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you. Certified off-road instructor. I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles.

Experience

40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range. Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland. Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
