Question about 2001 Isuzu Rodeo

1 Answer

Transmission will not shift into 3rd gear

After driving through some mud in 4wd low when i shifted back to 2wd my tranny began slipping when shifting from 2nd into 3rd gear. The next day it would not engage into 3rd at all. I can drive 20 mph up to about 29 mph. Then it shifts out of gear and i can coast back down to 20 mph and start over in 2nd. ATF fluid level is good. No leaks that i can see. Im broke. Should i even bother changing the fluid and filter? Or is there a possible sensor/vacuum/computer cause?

No problems before the mud deal but problems after the mud deal means that the problems started in the mud
check for mud in connections , wires disconnected , harness problems, vacuum hose to actuator broken or missing
run the fault codes to help point to a problem area
the transmission is sealed so there will be no need to change the oil or filter--just clean and check everything that is mud affected

SOURCE: Poor Shifting

Well, if it was low on fluid, and it was driven for a distance, you could of wrecked the interior gears of the tranni or other parts. I'm not a tranni guy but I know if you run a vechile with low tranni fluid you're asking for a new tranni or to have that one rebuilt.

possible range selection detent switch not working causing to get stuck some times in one range only and wont shift to other range 4wd light in dash just keeps flashing for about 10 seconds then goes to previous state this then can jam up 2wd 4wd lever that you then cannot move.
there are 3 switches 2 on trans/transferr case, 1 on front LH diff axle tube actuator (shift on fly). can cause damge to the electric actuator then on transferr case.
suggest you get a dealer to look at or some one that knows this system. is also vaccum operated on front diff shift on fly unit and there were 2 different systems fitted to these vehicles push button 4wd on dash and lever next to gear lever which i take is yours

Gather all you can on your transmission model and specifically how many and where the shift solenoids area located. If external, you can take them off, rig a little 12 volt DC power supply to activate each one while you spray it out with carb cleaner. Reinstall them and give it a try. Some have little screens that get clogged. Clean those too. Consider a professional flush and refill with synthetic fluid. If a four speed automatic, two solenoids can produce all for forward gears. For example both closed = 1st, solenoid A open and solenoid B closed=2nd, A closed and B open = 3rd, both open = 4th. Best of luck to you.

2002 ford ranger - Where is the 4x4 actuator located


On the transfer case
Transfer Case - Electronic Shift
The four-wheel drive electronic shift-on-the-fly feature electrically shifts the vehicle transfer case between 2WD, 4WD HIGH, and 4WD LOW. The system mode is selected by the operator through the mode select switch (MSS) on the instrument panel. The operator is informed which mode the system is in by two instrument cluster indicators: one for 4WD HIGH which appears as 4WD, and one for 4WD LOW, which appears as 4WD LOW. Shifts into 4WD HIGH can be made at any speed. When shifting into 4WD HIGH with the vehicle stationary, tooth blockage may occur preventing shift completion. When the vehicle is driven above 8 km/h (5 mph) the shift will complete. When shifting in or out of 4WD LOW, the four-wheel drive (4WD) control module requires that the vehicle speed be less than 5 km/h (3 mph), the brake pedal be applied, and the transmission be in NEUTRAL (automatic transmission) or the clutch pedal be depressed (manual transmission).
The gearmotor encoder assembly is mounted externally on the transfer case. It drives a rotary cam which moves the mode fork and range fork within the transfer case between the 4WD HIGH, 4WD LOW, and 2WD range positions.
The four-wheel drive (4WD) control module controls the gearmotor encoder assembly that shifts between 4WD HIGH, 4WD LOW, and 2WD modes.

How is four wheel drive used on a 1999 durango


Hi Ralph.

I do not own a Durango, but have owned many 4WD vehicles and can offer tips for proper usage.

The "L" and "H" after the 4 and 2 stand for "Low" and "High" ranges. The 2 and 4 stand for the number of wheels that can receive power from the engine and transmission. Most 4WD vehicles only provide power to 1 wheel on each axle (front at rear for a total of just 2 wheels powered) at any given time (but for purposes of discussion, we'll call it 2WD & 4WD, as advertised).

Generally, "2WD" is only offered as a High range and is the same as a "normal" 2WD car or truck. I haven't seen a car or small truck that offers 2L (but I haven't seen a Durango - so I don't know), but generally 2WD traction can be increased easily enough by simply shifting the transmission to a lower gear (From "D" to "2" or "2" to "1", etc.).

4WD is designed to provide additional traction whenever 2WD isn't sufficient. This can be when surfaces are slippery such as sand, mud, snow and ice or, when pulling a heavy load such as a trailer and tires are not gripping the surface well. Shifting from 2WD to 4WD High will provide more traction at the same tire speed. Maximum power from the engine does not come at low RPMs, so in order to get more pulling power from the engine with out increasing speed (or spinning tires), the transmission should shifted into a lower gear. This is especially helpful when pulling a trailer up a wet incline, etc. If 4WD High in 1st gear is still allowing tires to spin or not providing enough pulling power, then shifting the transfer case from 4WD High to 4WD Low will allow the engine speed to increase (providing more power) without increasing the speed of the wheels (reducing the chances of spinning tires).

4WD should never be used while operating on dry pavement. Since tires wear at different rates, and turning left or right slows the inside tire and speeds up the outside tire when compared to the rear tires, a certain amount of slip is required. Wet surfaces provide this necessary amount of slip - as does sand, mud, snow, ice, dirt, gravel, etc. You should take the time to see how each selection of High and Low affects engine speed and vehicle speed and how the surface and any trailer further changes traction. With a little experimentation, you'll see how it works and be able to choose the right range with little thought.

Don't forget to have the transfer case & front differential fluids checked and changed as per the manual. Neglecting this simple service intervals can leave you stranded when you need 4WD and can be very expensive to repair.

I hope this helps & good luck!

I have a 1998 chevy k2500 pickup with a 5.7L V8. The problem i am having is with the 4wd. it has a 3 button electronic shift selector. when pressing the 4wd low button it will shift the motor and the front...


First, you do not need 4 low unless you're stuck out in the bush somewhere. Secondly, when you shift from 2 high to 4 high, it goes in immediately. To access 4 low, the tranny shifter must first be put into neutral, wait five seconds, then shift into 4 low. To shift out of 4 low back to 4 high, you must shift into neutral for 5 seconds again. They both flash at the same time because you have not shifted into neutral gear with the transmission.

I own a 1998 Chevy Blazer 4wd that is on its 3rd transmission and I'm having the same issue where when shifting from 2nd to 3rd gear it's slipping badly my rpm's rev up to 3500 and I have to take my foot...


this is a known issue with the gm 4L60E transmission. the valve body in transmission causes this. if it is wore, then less fluid is sent to shift selonoids. thus causing torque convertor not to lock up, and this causes slipping. if it slips 2 consecutive trips then the transmission detects this and should turn on check engine light. ( p1870 ). you can see if the tcc solinoid is bad. but if not its usually the valve body in tranny.

Can some explain the proper way to shift from 2wd


4wd auto: you can shift into this mode at anytime. it is good for conditions where you might need 4wd.
4wdhi:: you can shift into this at speeds up to 30mph and both of these back to 2wd while in gear.
4wd lo : stop vehicle and shift truck into nuetral ok to be rolling around 3mph shift into 4lo then put in gear same when shifting back to 2wd

1996 ford explorer 4wheel drive will not engage into the hubs need to know how it works


make sure your 4WD switch is working.and fuse is okay.because your 4WD is control by 4 electric shift motors in which drive a rotary cam which moves the mode fork and range fork inside the transfer case to select between 2WD HIGH A4WD - 4WD HIGH AND 4WD LOW RANGE.a shift motor sensing plate on the shift motor monitors the range in which the transfer case is operating a transmission range sensor monitors the gear position of the transmission.which must be in neutral to shift into low.a pair of solenoids one for 2WD one for 4WD.mounted on the upper right firewall route vacuum to the vacuum motor which engages and disengages the center axle disconnect collar in the front axle assembly.a 4 x 4 shift motor relay module contains two GEM controlled relays which shift the transfer case shift motor between 2WD and 4WD modes.a solid state clutch relay activates the A4WDclutch inside the transfer case.

How do I use the shift on th fly 4wd system. I wanted to know basicalll what was the procedure. Do I put the tramission in a certain gear before I shitft the 4wd system or what?


If the system is a true shift on the fly you will be able to shift in 4WD while driving in forward gear, shifting in to 4WD high only. To shift in to 4WD low you should stop the truck and place it in to park or neutral. Also as you shift in to 4wd (or out of) try to do in a neutral state with the drive train, meaning not when you are accelerating or under heavy load. Make the shift when you are more or less cruising. PLease remember true 4WD should not be run on clear concrete or asphalt as the system must be allowed to slip. If you traveling on a snow covered road or such be certain to shift back to 2WD when on clear roads to avoid drive train damage.
I hope this may have helped,
Tom

Transmission wont shift into 3rd gear.


I had this exact problem on my 2005 5.3L Suburban... It would shift into 1 and 2 and reverse, but not 3 and 4.

I took it into a transmission shop, and he said the 3-4 shift solenoid was burned up. Wanted 1500 to fix it. Far from home, so I have to pay it.

Can't transfer to 4L or neutral mode


Transfer cases can be quirky. I've got a 91 Wrangler, an 86 Cherokee and a 75 Blazer. When I go from 2WD to 4WD, they each have their own personality.

There are a number of things I've learned to persuade a stubborn xfer case to shift.

Try mixing these :
  • Engine running, vehicle not moving
  • Engine off, Shift Xfer case, Restart
  • Tranny in neutral
  • Shift Xfer case 'N', Tranny in gear, Tranny in neutral, Xfer case to 4HI or 4LOW (as long as you feel it register), Tranny in gear, try to move
  • Shift Tranny to Reverse, roll a few yards
  • Lock/Unlock the Hubs
To get back to 2WD:
  • Drive for a few feet in a straight line
  • Unlock the hubs
  • Tranny Neutral
  • Shift xfer case
Let me know how it turns out.
