the lever gonna need to be pushed with a little force you no it not going to move like a knife thru butter

 

231 has 2h-4h-n-4l

 

Can somebody explain what "transfer case shifter is all the way back" means? In the picture mine is at 4 full time so what does "all the way back" mean?

"all the way back" means pulling the lever all the way back towards you.... so it would be in 4 lo. From your pics it looks like you are in 4all time, so no, you are not "all the way back" like the person stated. You need to be "all the way forward" in 2WD. It really sounds like your car got stuck in 4 LO, regardless whether its in 4 all time, 2WD or whatever. Put the transfer case shifter (the shifter that says 2wd,4partime,alltime, 4Lo) back in 2wd. Go slow, shift in reverse, drive, reverse drive a few times... don't jerk anything hard.

My ford bronco did this years ago, and I was just as gentle as possible and just played with it over and over.... finally I heard something underneath the car just finally shift out of 4WD.

Also, I just barely bought my first jeep grand cherokee, and the automatic shifter (not the transfer case) was very very loose. Sometimes it wouldn't start it Park, and I had to put it in N. It was only a loose linkage, and for about $40 I just went to jeep and got it tightened. I know this is kinda off subject but just thought I'd throw it out there, hoping it would help.

And so your cousin doesn't feel like a ahole... just tell him its all good, it's better you guys find this problem now, instead of some emergency situation.

 

i was gunna say he has a 242 not a 231

 

I realized in my previous post I called your jeep a car.

Sorry for disrespecting your jeep like that.

 

UPDATE FROM TODAY:

Recap of what is happening:
Not coming out of 2nd gear
35 mph or higher RPMs are above 3 and it feels like it should switch to 3rd but doesn't
Try to go up to 45 or 50 and RPMs will be pushing 4

So...This morning on my way over to my cousins house (10 minute drive) it drove fine AGAIN...RPMs and gears good on all counts...Keep in mind I drove it in the neighborhood several times in the morning adjusting the 4x4 and it had the PROBLEMS above with staying in 2nd...

Get to his house...Tell him how it was going smooth...I needed gas so left his house and also wanted to test it on the freeway...It drove fine up to the gas station then from the gas station back it drove BAD...Back to cousins house...We jack it up....shift it into 2wd....He is looking at the transfer case and seeing it shift when I am making shifts....We buy lithium grease and spray the metal.....We get ATM fluid and fill 1 quart into the transfer case....

We take it for a spin and it is BAD again....Try driving it a couple times and it is still BAD....

Then he decides we should go to O'Reilley's and check the codes...We drive separate....Jeep was driving BAD...He stopped to put gas in his jeep...When leaving and driving to O'Reilleys it is driving GOOD (shifting to 3rd no problem, RPMs low)....We get to O'Reilleys and I tell him to get in the jeep for a ride...It is BAD again.....Get 2 transmission codes P 1762 and P 1763 (basically Internal transmission failure and/or open or shorted circuit condition)...

Then I head home thinking it is BAD......It drives GOOD again...I get to go on the freeway and everything is great:

up to 40 mph around 1.5 rpms max
40 to 55mph around 2 rpms max
55 to 70 maybe 2 and a quarter rpms
75 to 80 it is at 3 rpms...
all gears shift perfect

The guy at O'Reilley's said it could be a bunch of built up gunk on the trans pan....

What do you guys think about this....I am hoping it was the fresh liquids and it just needed time and now everything is all fine and dandy but I suspect it will drive BAD again soon....

 

P1762 (M)
Governor Pressure Sensor Offset Volts Too Low or High
Sensor input greater or less than calibration for 3 consecutive Neutral/Park occurrences (4-speed auto. trans. only).

P1763
Governor Pressure Sensor Volts Too High
The Governor Pressure Sensor input is above an acceptable voltage level.

P1763 (M)
Governor Pressure Sensor Volts Too High
Voltage greater than 4.89 volts (4-speed auto. trans. only).

 

So basically it is an ON and OFF problem...Get in the jeep and pray it is going to run good that time...

Mine is an automatic...Are we talking an expensive fix in your guys opinion? Or possibly flush the trans and we are good to go!

 

This is what I found. Hope this works.

Have you already changed the tranny fluid and filter? How many miles does it have? If I'm correct I believe you have a 42re transmission, not an expert but it could very a simple electronic failure. Also maybe try adjusting your bands it does wonders, a typical tranny shop will charge you about 80$ to do it. Best of luck

 

I hope you apologized to your cousin you were really coming down on him like he was the cause of the problem. You are looking at about $200 in parts to fix these parts that are giving you the codes, the parts are located inside your transmission. What they do is decide the shift points and when your transmission can safely shift to the next gear. You really need to invest in a Chilton or Haynes Manual for your Jeep. The parts aren't that hard to replace but you'll need a new transmission filter kit (comes with filter and gasket) which is ~$12 and you'll need 4 quarts of ATF +4 (this is the synthetic, you could probably use +3 but the +4 is better) or if you are going to do a flush/total fluid replacement you'll need about 10 quarts and a 5 gallon bucket. When you put the new filter on torque it to 40lbs. Don't try and reuse your old gasket even if it looks good the new one is cheap. You are going to be into this deal a few hundred bucks but it should take care of this shift point issue you are having.

 

wow. well, someone is going to have to drop the pan and make sure the trans is not burned up. If there is no significant amount of metal or clutch material than changing the governor pressure sensor and solenoid should fix your problem.
This is very very common with these transmissions and not too big of a job. As recommended earlier get a new filter, (just dont torque it to 40 ftlbs. the bolts go through the valvebody so more like 12) and a new pan gasket if yours does not have the reuseable rubber coated metal gasket. Dont use cork. ask the parts guy if they sell duraprene.
Use atf+4.
do not drive it until you fix this or you will be replacing the trans.

 

Thanks everyone for excellent responses...Looks like we finally got to the bottom of this and I'll have it fixed within a couple days...

My only question is some links say replace the pressure transducer and pressure sensor along with trans filter....

Others say governor pressure sensor and solenoid...

I'm guessing pressure sensor = governor pressure sensor

My question is does solenoid = pressure transducer?

Thanks again...

 

Sensor=transducer

 

I called O'Reilley's and they have 3 different types of the solenoid...Mine does have the O/D button that is not functioning great so I'm thinking the third option is the one I would need? Not sure...I think I am looking at around $240 for parts only....

1) An 8 pin w/ black

2) A 2 pin w/ yellow

3) O/D Torque Converter lockup
