99 jeep grand cherokee limited, have no 4wd. fluid was empty when i got truck filled case, still no 4wd. 242 quad trac. put vehicle on lift shifted into drive rear wheels only engage. any ideas?

what is the question.?
snarky answer "we give you permission" hehe
but my guess, is what fluid is it? that it/,
i presume you see the 2 plugs. there. fill and drain>?
always remove fill plug first. (if cant stop, do not drain it)
242 and 247 have different fluid capacity.
3pints and 2.5 pints respectively
the operators guide tells gear lube used there.
chapter on 242, example.
Dextron II is not correct in 2016, only DEXron VI. (newest grades are always best )
do not mix them, drain and fill with only one class of lube. 100%

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)

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.

i'd advise taking to a autobox repair shop as sounds like an internal problem , only thing that can be done at home is to check the fluid level . follow link for more info
Checking auto transmission fluid level JeepForum com

A bit more information would be handy. If it is only a how to check the T-case fluid then its simple: just remove the upper (fill) plug on the aft side of the T-case housing. The fluid should be at the top of the hole or even spill out a bit. The jeep should be on level ground to do this check right. Which fluid it eventual needs depends on which T-case it has.

Which transfer case you have 242 (Selec-Trac on the shifter bezel) or 249 (Quadra-Trac on the shifter bezel). If it's a 242, you're looking at probable linkage adjustment which is done underneath the vehicle. If it's a 249, you're possibly looking at viscous coupling (VC) lockup.

Adjust the shift linkage; heres what to did...



...the blue arrow indicates where the linkage originally was (the lock nut screw), moved it down the green rectangle is showing the back of front driveshaft near the tcase, just for perspective.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

the 242 is the correct transfer case for your car.Its the selec-trac transfer box.The other type is the command-trac.Both types were used in Cherokees.Hope this helps

Use ATF+4

Do not use Dexron or Mercon

the quad trac is an alltime 4wheel drive system. it does have a control module that helps transfer the power from front to rear. if it is a 2008 it should be under warranty and you can have it checked out for proper operation

Both the transfer cases used during that time look similar. See the following diagrams:

NV242: http://www.wjjeeps.com/nv_242_01.jpg

Here are instructions w/ pics:

(If you have the 242 I believe you can use ATF+4 instead of the special Mopar fluid but I would check first to make sure).

while moving about 2-5 mph, shift your transmission into neutral but keep the vehicle rolling, then move the transfer case shift from 4HI to 2HI.
