My 97 Jeep Grand Cherokee was doing the same thing. I changed the TPS ( Throttle Position Sensor) Now it is great goes into overdrive fine. It is really easy to change.

SOURCE: shift indicator light 1999 Jeep Grand Cherokee

There are two parts to it, a voltage resistor, and the EL panel itself.

You need to remove the console first. There are 2 screws under the front rubber pad, two under the cup holder, two in the bin. Remove those six first, take the storage bin out, then slide the rear cupholder out, remove the two screws under the cup holder, and one in front of it.

There are a total of 6 flat screws, and 3 self tapping screws you have removed.

Put the parking brake on, shift the tranny to N, and the transfer case to the middle position if equipped.

Remove the entire console. Slide the shifter beezel as far up vertically as you can. There are 4 clips you ned to remove to do it.
You will see a blue and black wire running into the back. Follow those wires to the resistor. You will see a transparent EL panel attatched to the resistor by two clips.

Usually, one or both of these clips has come loose, causing the light to work intermittantly. Clip them back on, and turn on the headlights to confirm that the light works correctly now.

Re-install everything in the opposite order.

SOURCE: I have a 1999 grand cherokee. The check engine

Hi, Your like your jeep is in limp in mode, this is to keep you from burning up transmission and to get you some were off the road, the p1768 code means A/T Transmission Relay Output Always Off. This should be checked out by your local shop or dealer. but you should make sure that the fluid level is correct, if to low there is not enough fluid pressure for the solenoid's to engage the relays. Hope this can help you out. If i can help you anymore fell free to re post.
Thanks dodge tec

02 Jeep Grand Cherokee jumps out of overdrive while driving on highway.


The torque converter is where OD takes place. Look at your transmission fluid cooler to see if it's blocked. The TCM module controls the OD functions so it may not be sending the correct signals.

I have a 1999 grand cherokee. The check engine light came on with a P1768 code. If I keep the trans in the "drive" position and start off, it feels like the transmission is in 3rd gear. No...

My 1995 Jeep Grand Cherokee transmission slips in overdrive


sounds like a possible shift solenoid. If it's due for a fluid change, do that and add a container of lucas trans conditioner. Likely you have a drain plug on the pan so if the fluid was recently serviced, just drain a quart out and replace with the additive, then top off.
If the condition does not change within a week, likely you will need better diagnosis from a reputable trans shop.

1993 grand cherokeeoverdrive button light stays on ,no overdrive


The button itself may be bad. If the button is ok, then the problem could be in the transmission control module located behind the dash or worse, it could be an internal problem with the transmission itself. I would start small by checking or replacing the panel that includes the overdrive button. The easiest and cheapest place to get one is a salvage or junk yard. If this doesn't solve the problem then it is best to take your Jeep to certified mechanic. When it comes to the Grand Cherokee, they used around 5 or 6 different transmissions and several different transmission control modules. I wouldn't recommend the do-it-yourself guy try working on those systems. I Just recently replaced the transmission in my 93 Cherokee and finding a used one that was actually the right model was like looking for a needle in a haystack

Overdrive cuts off buy itself while driving


when the transmission overheat light (this is for the fluid) comes on the transmission control module pulls the trans out of OD to try and cool it down, this is called failure mode strategy, it is built into the programming of the control module, the signal from the trans is most likely incorrect, but the module doesn't know that, replace the transmission fluid temperature sensor.
