Shutter and Stumbling issue

Hello, I've got about 12K on my 2009 Ranger Sport/ Auto tranny. When my truck goes into OD and the TC locks the truck now stumbles/ shutters/ jerks, especially with the AC on. In fact with the AC on it's allot worse. I took it to the Dealer and they replaced the #5 spark plug and the problem is not as bad but it still does it. Would a tune from a SCT Tuner fix this problem? I have a feeling the Dealer did a quick fix by replacing one spark plug instead of all of them. Now I have to go back to the Dealer and explain it once again.

This truck it too new to have this problem, anyone else have this problem and what was done to fix it? Thanx for any help here.
