Tranny wont go in gear but truck seems stuck in park..happened while stuck in snow going from drive to reverse..any ideas on what may be the problem

your shifting pattern seams off , as follows P R N D D1 D2,
Will it go into any gears closer to park ? did you try turning steering wheel , next I would look under at tranny linkage to see if there is something stopping it. that will require 2 people 1 in truck and 1 underneath.

Giving your some diagnostic tools for your reference :http://www.xcardiag.com/ hope it can help you.

Either your drive bands or your drive servo is bad in your transmission...you burned it up

check that the selector on the side of the tranny is tight and properly adjusted. Re adjust so that gear selected lines up with lights

transmission probably slipping gears or some of the gears are broke in the transmission

There is a recall on your tranny take it to a Jeep dealer and tell them you waant the tranny recall done ours did the same thing, there is some seal that goes bad.

Also, I quote this comments form other owners with this problem:
Our 2005 grand cherokee had tranny poblems at 30,000 mi. It was a bearing in the trans. They rebuilt it under warranty. the symptoms: when you shift from park to drive and step on the gas there was a delay and it would bang onto gear. They said this was a problem on a lot of Laredos. Now at 50,000 more tranny problems. not shifting right, the engine light is on and it lights up around all of the tranny indicators on the dash PRND will all be lit up. After several trips to the dealer it is the Trans Control module or TCM at a cost of 400.00 and of course not covered in the 70,000 mi warranty.

Them, I suggtes scanned the TCM for any stored codes there.

Good luck.

the rod you mentioned is called linkage, yes it's posible, snow may have jammed up under the car and is stopping it from properly engageing, or the grinding could be internal in the transmition, jack the car up, put jack stands under the frame,block the tiers, and take a real good look at were the linckage conects to the tranny, good luck

Stuck in snow, if you spin the tires for a prolonged amount of time you can overheat the transmission and damage it internally. Without seeing it, my best guess is that's what happened!

i hate to tell .but your going to need a tranny. you smoked your reverse. have a good day

your tranny is done- old and tired
