Have Transmission Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.working after noon till just after midnight.
On the transfer case can you remove the shift motor and manually shift it into 2wd?
Do you own a volt meter and scan tool to diagnose the 4wd system?
With the shift motor off and the 4x4 commanded to shift, does the shift motor move? If it does then your looking at internal issues in the transfer case to blame for this concern.
This is my 1st answer, but does not have to be my only answer. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. Please let me know if you are pleased by selecting a star rating above or by replying and saying your pleased. Not rating or rating 1-2 stars does not benefit you nor me in any way. Follow up and reply as often and when needed, there is no extra charge to do so.
Since you have a volt meter you should be able to do most of the tests needed to see why the transfer case will not shift. Use the links below.
Hello again Chris here,
With the transfer case shifted manually and it did not change gears this means the shift cam is broken or the shift forks inside are worn. Going into the transfer case is next.
