Re: 2000 grand cherokee limp mode?

Your jeep is a WJ, so better to post in the WJ section next time.
The P0700 is a generic transmission fault code, it only tells you that the TCM (transmission control module) has set one or more fault codes. You need to have it scanned to know what the problem is.
The P1491 has to do with the radiator cooling fan control relay circuit open or shorted. Does the engine temperature goes to redline when standing still and idling?.
P1492 is a battery temp sensor problem. This sensor sits under the battery and is used by the PCM (powertrain control module) to regulate the charging current of the battery. There is a connector below the battery tray which you could check for dirty or corroded pins. Let us know which fault codes show up for the transmission.

It goes up to 2000 rpm upon start up and then idles at 1000 for a bit new to the whole Forum thing but appreciate any help u may be able to give

Re: 2000 grand cherokee limp mode?

By doing the keydance you will only see the generic P0700 code. Since it is still not working well, you should let a shop clear the PCM and TCM faults, test drive it and then see what will show up.
But before that, check Fuse 5 in the PDC (power distribution center) under the hood. If ok, swap the transmission control relay, also in the PDC, with the auto shutdown relay (in PDC). (if the relay is bad, the engine will now not start and you know what to replace.) No power to the transmission control relay means full time limp mode (3rd gear in D, or 2nd gear when in manual 2)
Regarding the high idle rpm, clean the idle air control (IAC) stepper motor and air canal first. The stepper motor is mounted on the throttle body right hand side, when standing in front of the jeep. It sits just under the TPS (throttle position sensor). One connector and two screws and it is out. Do NOT swist the IAC plunjer during cleaning, because you easily break of some internal plastic parts which should prevent the plunjer from rotating. If this will not solve your issue, you need to check if the accelerator cable is not binding and keep the throttle plate a bit open. A scanner with live data could show you the TPS position in %, which should be around 12% in idle. If this seems to be ok, most probably the TPS is going bad.

Re: 2000 grand cherokee limp mode?

Did you swap the transmission control relay with the auto shutdown relay?
Check the large connector on top of the solenoid block if its well connected.

Re: 2000 grand cherokee limp mode?

Re: 2000 grand cherokee limp mode?

The first picture is showing one of the O2 sensors. (and a second one in the background)
Second and third picture seems to show the line pressure sensor connector. Is this on the right side of the transmission, close to the exhaust hanger?
I do not see the partly melted connector on the last three pictures.

Re: 2000 grand cherokee limp mode?

You showed the melted connector, but i have no idea where the wires go to.
The last pictures didn't show the connector at all.
If the wires go the the O2 sensor(s), then this is not your problem with the limp mode.
