Check the condition of the tranny oil on the dipstick. If it's black and smelly, the tranny clutches might be worn out. Make sure you have enough fluid in there first. Check the fluid with the car engine running and the tranny in park. The level should be between the 2 marks.

Check the Trans fluid level with it running and at operating temperature. Jeep NAG1 transmissions are known to have the input electric seal leak trans fluid. Not an exspensive fix add Mopar ATF4 and then relace the guild seal.

SOURCE: Very rough idle on 2002 Jeep Grand Cherokee Limited Edition V8

If you haven't changed the plugs or had the fuel system cleaned, now would be a good time to do it. The number 1 culprit for rough idles is dirty injectors or plugs. You can try an injector cleaner in a can (or bottle) for under $10 and see if it helps, and then work from there. If there isn't any improvement then if you are able to, check the plugs for any gunky buildup and if you find a bad plug, make sure you replace them all (or have them replaced) at the same time.

your transmission is in "limp home" mode, the problem is one of the sensors on your transmission. you need to have an obdII scanner connected to read the codes stored in your vehicles computer. this will tell you which sensor has failed

SOURCE: 2002 jeep grand cherokee with 4.0 engine will die but restart

p0340 is the cam shaft sensor, this will cause it to cut off while driving, hardtime starting, p0351 is the ignition coil A primary/secondary curcuit mal function. p1391 is ignition system misfire, this could be plugs, wires, or coils. first of all have the cam sensor changed and it may correct the rest of the codes. when fixed turn light off with obd2 scanner. if you do not have one, then any auto parts store will erase the codes fo free of charge.

What are the symptoms of a speed sensor going bad on a 1997 jeep grand cherokee laredo 6 cyl.


Since alot of things rely on data from the speed sensor you will "usually" get an ABS alarm, little or no shifting,no indication of speed on the speedometer, and the check engine light. without the abs light and with a speed indicated I would lean toward a transmission problem

first check fluid is full by starting the engine have it blocked put in in nutral( to fill the bell houseing ) then check fluid level, more than likely you need to add fluid exspecally if your checking it in park with engine on or off park gives you a false reading on the dip stick

2004 jeep grand cherokee engine management light on gear box won;t change up or down . had this problem a few times; just used to stop the car turn engine off @ back on car would drive ok, after a mile...


I had a similar issue on a grand cherokee '98 4.0L, and it was because the gearbox was overheating due to old oil and the fact that is was low on oil. Change gearbox oil and the filter inside the gearbox checked the two band tension and adjusted them and all was ok. the oil should be red or a dark pink. It would point more to this being the poblem if when it does change gear, the gear changes seam slow or slugish or change happens at higher engine revs. You may be able to get a fault code from ecu, by turning ign. to acc then on then off then on then off then on then off then off hen on again (code is displayed instead of odomitor reading as PXXXX or POXXXX). This could point you i one or more directions if oil seem to be correct.

1st gear issues on my '96 Grand Cherokee Limited.


rip the gearbox out and fit a manual ,or scrap the truck because the cost of repair is greater than the resale value of this vehicle ,its worth a 1000euros if you get the right person ,4litre engine petrol ,road tax is astronomical and at 7 dollars for a gallon for fuel you can see where these gas guzzlers end up

Grand CherokeeTransmission needs high engine revs to work


Hi Ghecham,
I have done some research and it sounds more like the torque convertor may be the problem,As the speed sensor would affect the whole speed range and not just the range under 3500rpm's
I will continue to check on other possible causes while you are having the other parts replaced.

Thanks again

Auto gear problem


You will want to check your transmission governor transducer on your transmission, and if you have to replace that...after you begin to drive it the computer system programs the shifting for you. It takes a couple days to get back to normal shifting. Run diagnostic testing on the transmission first, and see if you get a communications failure.
