What is your question?
If I change transmission & put a rebuilt transmission in, do I need to change transfer case also? Truck won't shift gears. Changed transmission twice. Still nothing. Changed vss.
How long has your 2003 GMC Sierra 1500 had this problem?

If you are saying you replaced the transmission twice and you still cannot engage a gear, then obviously something else must be wrong. What that is, I don't know. A transfer case that is not functioning properly can influence engagement of gears. But it would be assumed that you would have checked that. What diagnostic testing went into replacing the transmission in the first place? Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
