I have a 2005 jeep grand cherokee with the v-6 auto trans and sometime all of the trans indicators light up at the same time and gives me a drivability issue. What would cause this? the dealer has had it three seperate times and since they cant duplicate the proplem they don't know what to do.

I take it to the dealer when the check engine light comes on and of course by the time i get it there the light has turned off and they say they don't know what to do.
This is a rather common problem, I'm suprised they are having trouble diagnosing it.
Your jeep has an electronically controlled transmission, with 2 computers.
transmission control module - does all the shifting, etc..
electronic shifter module - located down in the shifter assembly. basically all it does is relay what gear your in to the transmission control module
95% of the time it's caused by the electronic shifter module not relaying the proper information to the transmission module. That's why your display gets wacky, as the car doesn't know what gear your in. Make sense?
The fix is to replace the electronic shifter module. Hopefully your still under warranty, as they are quite expensive, for what they do.
This problem will store a code "implausible data recieved from electronic shift module". Even if the car is back to normal operation, and the light has turned off this code will be stored in memory. If it's acted up recently (say last 300 miles or so) and nobody has erased the codes, I'd try another dealer, they should have no trouble diagnosing it.
I hope this helps answer your question, if so please click accept. If you need more information, don't hesitate to ask!
