My Isuzu Rodeo won't shift into any gear besides park or neutral.

we cant guess your drive line, not now or ever.
so why ask. us?
my guess you mean the car drives in 1st gear but will not upshift,
and flares, in a false neutral.
wont and want is speed wrong 2 times, why?
Is car with TOD? torque on demand option, we cant see the dash board, we be like blind.
check fluild levels yet,
get the box serviced last decade, (a full flush and filter,) sure no.
check fuses, maybe car has TCM that cant up shift due to fuse blown.
and last did you scan it, if not why not
that be 3rd step after levels, fuses, then scan.
if the TCM cant see sensors, it cant upshift,
TCM is the tranny brain.

Cars have a locking solenoid that prevents the vehicle from being shifted out of Park when the engine is running if the brake pedal is not pressed. This is to prevent accidental shifting into gear by children left in running cars, or people leaning over the shifter to get to the glove box, etc. Sounds like the solenoid is not being deactivated when the brake pedal is pressed. There is usually a manual release button in case this feature fails, but the button may be inconvenient to access. You could try putting the car in Neutral before trying to start it, since most cars will start in either the Park or Neutral position. This will allow you to use the vehicle until you can diagnose and make repairs.

car 2wd/ or 4wd.
will not shift into any gear. reverse too, wont move?
well as with a/t boxes this.

1: check fuses first. if the 4l30 it need power to the tcm.
but will still car moves if the lever moves. even fuse blown.
2: the levels right ,per operators guide, do not use engine oil level style checks or make it WORSE.
3: a new filter, kind makes sense in all cases.
4: you shifted to DRive, but did the box shift to drive, under car.
look, there, have help shift and you look
this is called the MANUAL valve lever, if it fails to shift right
it will not work. super simple cave man stuff here, a cable.
must shift out of park and out of neutral or car will never move.
5: lots more, but that is par for course on all a/t boxes .
6: line pressure test pass? (fsm book shows this simple test)
if that fails the box is bad. (low pressure)

Have you retrained the gear? From memory think goes motor running foot firmly on brake park to neutral three times, neutral to reserve three times, neutral to drive three times, keep going thru all gears Then drive car normal for ten minutes minium as you usually would.

Did you try starting in neutral. Maybe you confused the ECU and caused the starter inhibitor switch to malfunction. Try disconecting the neutral on the battery and wait for a few minutes and see if she resets..

Hello
The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

This could be the problem. If your dash indicator is showing reverse but the transmission is in park it could be the safety switch. I'm not talking about the safety switch in the transmission though. In automatics they put a second switch to kill the starter from engaging. You need to adjust the linkage. If your shifter isn't actually on the column but the indicators are there is a cable that attaches the floor shift to the column and that is adjustable. Put the Floor shifter in Park and turn the column section nearest the dash by hand until you find park. Then adjust the cable length as needed. If all you have is the column shift it is still a cable adjustment. Set the emergency brake, drop the shifter to low 1 and adjust the cable linkage by loosening it on the transmission and manually move it all the way to low 1 then tighten it down then move the shifter to park and repeat teh adjustment process to verify that it is properly aligned. Lock the linkage back down and see if the vehicle will start, if it doesn't move the shifter to neutral and try to start the vehicle if the vehicle starts then check the column shift safety switch at the park position to make sure it is still in place and working. Typically, if the vehicle won't start in Park or Neutral it is more likely to be the Transmission neutral safety switch.

I have the same problem few days ago, and still didn't find any solution. Can any one please help?????7
