Welcome, I'm Chris (aka Moose). I normally log in after 3 pm central. Please make sure to let me know exactly what is needed from me so I can provide EXCELLENT 5 STAR service. Is the vehicle 4x4?Will it roll in any gear other than park and will it not roll in park?Does reverse work?So far you have described a possible broken input or output shaft inside the transmission. -------------------------------------------------------------------------------------On your screen at the top you should see a rating 1-5 stars and a green submit button. Please make sure to select one and press submit. I am not compensated by the website unless a customer rates. Rating only pays me from the deposit you have already made, it does not charge you more, nor close the post. Also all follow ups are free and welcome.Thanks Chris

It's a 4x4 it rolls in every gear including reverse like neutral and it does stop in park. Reverse doesn't work either it rolls like neutral and it won't go with 4x4 engaged either.

Since it rolls in park that means the most likely failed parts are the transmission output shaft, the transfer case, or the shift forks inside the transfer case. Since it rolls in park this rules out the internal components like clutches and bands in the transmission. Getting the transfer case off is the first step to see if the trans output shaft turns in park. If it does not then take the transfer case apart.

It does not roll in park.

Expert:  Chris (aka- Moose) replied 7 months ago.
Sorry I misunderstood. So that means the break is not in the transmission output shaft nor in the transfer case. Its a concern inside the transmission with the input shaft, rear planetary, or the pump. The next step prior to remove and overhaul would be a line pressure test to check the pump.
