Why my 94 Isuzu rodeo wont change outta 2nd gear

You received good advice yesterday when you asked the same question. You also asked this question over six months ago. What was the problem then? You can keep asking the question, but you will get a much better answer if you take your Isuzu to a transmission shop and have them check it out for you. It appears your transmission is in 'limp-in' mode, and won't be fixed until the problem is diagnosed and corrected.

Transmission needs rebuild

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.

I found all I could locate for you Ann. I hope this helps. Thank you and leave feedback

It could be in fail safe mode. Try scanning the vehicle first if the check engine light is on. Diagnose the trouble codes first if any. Clear the codes and drive to see if it makes a difference. Now check the fluid and if it is varnished and has a burnt smell, take it to a transmission shop.

Did the problem exist before you changed the fluid? you can try some conditioner to see if the internal seals may be a little tired.

The cheapest troubleshooting recomended: change filter and fluid. I use mobil synthetic.

You might want to consider the clutch and pressure plate, throw out bearing, and pilot bearing,rear main seal, check your U-joints and CV joints

Will it come out of gear with the engine off? if so probably the clutch slave cylinder is bad. I have replaced it 3 times on my 94
