My 14 6.7 has a manual shift 4wd. When i put it in 4h i get a serv 4wd amber light. it will go into 2h and 4L. One other thing i should note is i had a grommet missing where the shift linkage connects to the transfer case. I replaced that grommet but still having this issues. Any suggestions or help would be appreciated. Getting lots of snow and cold weather here in Colorado.
