Isuzu rodeo sport 4wd, stuck in 4wd

auto trans no less.. it shifts no you.
so what trans is there?
so reverse works, 1 gear, then 2nd , but not 3rd.
some have a TCM that does the auto shifts.
and must be scanned to see why it wont shift.
levels ok, that be like first first. done not like engine, ever.
do it correctly.
The TCM may have flash codes, the FSM factory serv. man. covers this, as does mitchells.but it will ask you
what engine you have, and which trans is car 4wd?
first know your drive train then ask.

why double post and not add info????

like engine size ?
4wd?
and trans model.?
best i can tell your trans has no TCM.
so is true hyrdamatic. (no computer brain shifts)
so needs many tests first. to find why it will not upshift to 3rd.
governer? be on top of list.
as is stuck TV cable
or leaking vacuum modulator valve. if it has one.
if you have this trans. on the big V6
then
4L30-E.

see that E on the end, it is TCM shifted.
the trans has a side plate that anyone can read, tells you what is there.
here is the wiki on it.
https://en.wikipedia.org/wiki/GM_4L30-E_transmission


read that?



see the 2 solenoids 425/435?
if yes, that is TCM shifted box, and must be scanned or do the FSM book, TCM flash codes, the book tell you who to do that.

this is a TCM brain auto shifted box, and must be scanned first
if the trans slips, that is a WHOLE OTHER MATTER.

this is part time 4wd
drive to dirt and deselect 4wd,
do not engine PT 4wd on dry pavement or risk damage to drive line
RTM read the manual in the glov e box.

most vehicles get stuck in 4wd low when they arent shifted into neutral before removal also check the lins to your front differential

Hold on your dash is telling you that (active trac) is on. There should be a botton on your dash listed
A/T MODE just push it and the HOLD should go off.

not transfer case motor....there is none on a rodeo....trooper has torque on demand.....rodeo problem is likely shift on fly mtr...mounted on front axle....if u dont use 4wd regularly it sticks and gets stuck.

Try Reversing i had the same problem and i backed up about 25-30 feet and it came out.

This will help

I had this happen to a 1999 4x4 LS and my sisters boyfriend mentioned to periodically turn 4x4 on/off at least once a month.
What I did was go down a stretch of road slowly and attempt to turn it on/off till it became unstuck.
Drove around 10 miles on a road that was hardly used...to get the stupid light to quit flashing I had to put it in park and try to creep forward ---while using off settiing or put in park then reverse...while using the off -setting on 4x4. My patience paid off. They get sticky...you must be cautious... because there is a way to cause vibration and then it won't start...some deadman feature that I experienced once and the LWD must have slipped in a little and I had to look at everything.
Mine is an Automatic with the shift on the floor...that can get sticky too.

Good luck and hope this helps...mine had lots of growing pains but I get 23 mpg and it runs/idles better and the only gremlin left is some short in the dash which leaves the lights D/3 (one or both on)for the shift indicator on:)
