When my 07 4x4 1500 down shifts from od it will sometimes have a small vibration. Doesnt affect the speed and just does it for maybe a sec. Its not slipping and seems to be worse when cold. Have plans to do a filter and fluid change tomorrow just sonderin if it could be a converter shudder. All feed back is welcom.

 

since you have an '07 i doubt a fluid/filter change is the problem. that's not due for 50kmi really and technically you could drive 100kmi on the original filter/fluid as there are 2 filters and the fluid is fully synthetic from the factory. For just a pan drop, your looking at $100.

You sure it's not the MDS kicking in that you are feeling/hearing?

 

yea im sure i un capped the e cut out it feels like converter shudder but not really that bad.
