I recently changed fluids in my 2004 GMC 2500HD. Trans, diffs, transfer case (Dex 3).
Today I was plowing in 4 low, and started to hear an odd noise from the transfer case.
- 2wd and 4 high, no issue.
- When switching into 4 low, put it in neutral, push 4 low button, light blinks then goes solid. Still no noise/issue.
- When changing from neutral to drive, a noise starts, like the gears in the transfer case are hunting to mesh together. Now, it won't actually go into 4 low. 4 high still works fine.
Any thoughts before I visit a trans shop?
