SOURCE: window motor replace 2001 jeep grand cherokee

You need to remove all the skrews from the door. Normaly there is one in the handle of the door, one behind the in door lach handel and one under the bump out for the arm rest on the door. Than you need to take a flat head skrew driver slowly priying the panel off. There are plastic clips on the backside of the panel it is ok if you brake a few.

SOURCE: transmission will not shift to next gear. 2001

If this is a manual transmission and your can't get it to go into the next gear, your clutch is probably worn out and needs to be replaced. When the clutch pedal is pressed a space in the gear box allotted for the shift stick to get in. If that space is not being created, the clutch is not working properly. I say get your clutch check out.

SOURCE: transmission will not shift out of low on my chevy

P0700 will come up with most all codes or faults to do with a transmission,P1781 is 4X4 switch out of range,I have never heard of a P1721 but a P0721 is trans output sensor range or performance.If the computer isn't getting a output speed it doesn't know that it should shift.I would check all your wiring down around the trans area looking for broken or grounded wires if ok have the speed sensor checked for being opened.

My 2001 jeep grand cherokee wont shift into 4th it only goes to third what would cause the 4th gear to not engage


There are several things that could cause that.
> Replacement transmission not equipped with overdrive
> Overdrive solenoid in replacement transmission defective
> Overdrive control circuits damaged or loose pins or connections.
> Gear shift linkage or cable out of adjustment
> Transmission range sensor malfunction or out of adjustment

Since you have a computer-controlled transmission, it would be better to ask the onboard computer that question....you will probably get a much more definitive answer.

2002 grand cherokee, overland 4,7L engine doesnt


Hi Joko,

What you are describing is a failure of a main circuit. The first thing you should check is yo make sure that your battery is in good condition and that the cables are clean and tight. Let me know if yu find anything wrong there. Then there may be another main circuit problem. Check all of the fuses in your fuse block in the engine compartment. If any of these fuses are blown, it will usually cause several things to not work. If you find any fuses blown, DON'T REPLACE IT YET. Let me know WHICH fuse is blown and I can help you find out why it blew so you can get the problem fixed.

Get back to me on this and we will continue.

What does these codes mean P1781, P0731, P1784 AND P0700 AND HOW DO I FIX THEM.


p1781 is manufacturer control transmission, p0731 is gear 1 ratio incorrect, p1784 is manufacturer control transmission, p0700 is trans, control system malfunction. all of these codes refer to tranny.This code normally points to a faulty transmission control module, but this is an expensive part and you should have an experienced Dodge technician diagnose the problem first. or a transmission specialist. the other codes are probably associated with the p0700 code. have a good day !

I have a 1999 Jeep Grand Cherokee Laredo and the transmission doesn't work first thing in the morning. Once you have driven approximately 1 block, stop put it in park, turn the engine off and then...


If it were me, I would try replacing the pressure switch and see if that fixed it.
I looked it up and it appears that switch may be deep inside the transmission, which might mean it costs big bucks to replace it.
God bless your efforts.

I had a shifting problem. The car would start in the wrong gear and shift at wrong times. I repaced the governor postion sensor and tranny fluid and the problem has been fixed for several years. Did you replace the tranny fluid?
