Hi.

First ensure that you have wired the selector switch in the proper way. An incorrectly wired switch will explain the problem.

Did you test the switch before replacing it? The problem could have been the transfer case itself. In that case fixing the transfer case will be a challenging repair. See troubleshooting and repair at pages. 1378-1379 0n service manual. Manual available here:Jeep Manual FSM Grand Cherokee WJ 2001 - Manual 01WJE.pdf

    The switch is a plug - just unplug and reinstall new one - only one way it will fit. I'm downloading the manual right now.

    Did you also check the transmission fluid? This will explain the reverse not working, and can also cause the 2WD 4WD selector getting stuck. I will have a look at wiring diagrams, but I cannot think about any electrical problem that can be related to no reverse and 4WD selector, the two things work separately.

  • lbarrus May 25, 2010

    Fluid is full - vehicle will go in reverse when vehicle is on the lift / off the ground. As soon as you put the wheels on the ground, feels like it wants to shift but won't.

    There is a Jeep service bulletin called Delayed Engagement Due To Cooler Return Filter Replacement

    This may have to do with the problem. The filters cause delayed shifting and problem of this kind only after maintainance is done, or when the car rest for a time. Your vehicle may be included in the list of vehicles affcted, and the return filter may be causing the troubles.In that case you will need to replace transmission filters. Below the bulletin.

I have a 93 jeep Cherokee, it will move in 4wh and in 4wl but will not go back into 2wd?


Hello guy
try posting what 4wd system you have,? first.
command trac or select track, (the latter is full time)
part time or the full time system,
we cant guess it....
read the operators guide first, if a part time system only
as i suspect, stop driving on dry pavement.
it's only for ice, or dirt. part time. part time is not a full time system.
Command-Trac
shifting to 4wd on dry (means no ice) pavement causes, drive line wind up! and the gears to lockup. (see steering get tight in turns?> and is dangerous to drive it like this , you, me and the box)
posted here 100s of times.

http://www.rubicon-trail.com/4WD101/driveline-bind.html


the non grand Cherokee. early

had these choices
  • 1987-2001: New Process NP231 Command-Trac, part-time only, 2.72:1 ratio with low range
NP231 has the following settings: 2HI, 4HI, N, 4LO
  • 1987-2001: New Process NP242 Selec-Trac, full-time or part-time, 2.72:1 ratio with low range
NP242 has the following settings: 2HI, 4 full-time, 4 part-time, N, 4LO


as you can see you need to first know, what NP box you have or
photo your shift lever for 4wd, an post it and we tell you.

more facts, on select trac. (totally unlike command trac)
Selec-Trac locking hub is used on 4WD Cherokee. Selec-Trac
utilizes a non-disconnect front axle. Engagement of 2WD or 4WD is
accomplished at transfer case by means of mechanical shift linkage.
System allows full or part time 4WD. Selec-Trac can be shifted into
2WD or 4WD modes from inside the vehicle at any speed.
unquote
next from the service manual,
4WD TO 2WD
1) Place mode select switch in 2WD position. Transfer case
should shift to 2WD and not allow shifting into 4WD or LO range. Axle
should shift after transfer case shifts.
2) To determine if front axle has completed a shift out of
4WD into 2WD, position mode select switch back to 4WD position while
operating vehicle at slow speed. If vehicle shifts into 2WD, axle will
ratchet. If shift is not completed, transfer case will shift into 4WD
and hissing sound will come from mode select switch.
end quote.

if unsure read the FSM book its free.
shows you both systems and how to diagnose it.

in the box, click Cherokee,,then click 1993, and behold.
the real deal.

With any 4WD like this, always move a few feet in the opposite direction when disengaging. If you were moving fwd in 4wd, switch to 2wd, back up a few feet, then go fwd.

96 grand cherokee 4wd doesn't work


try lubricating all your linkages and always make sure all 4 tires are the same diameter. this makes shifting in and out a lot easier. you are shifting it on the fly right?? not stopped?
