2010 Silverado dragging feel during acceleration.

[Comarade Lee]

Hi folks, hope you guys are having a good day. I have a 2010 silverado 1500 and just had a new flush transmission oil (16 liters), change of new filter tranny, and a new rear differential fluid change.

The mechanic pull the tube on the radiator to bleed the oil transmission oil out and fill.

After having it change, the shift is good and when pushing the gas slow it runs smooth. But once you try to floor it, it has a dragging feel underneath the driver side.

Its very noticeable also when the truck is at a very steep hill and you could feel a rough/dragging acceleration on the driver side floor. My friend also could feel it behind the passenger rear seats as well.

When doing a full turn to the left, you can also feel like something or some parts are loose or something is jumping underneath it. No clunking or tug sound.

I also have this weird tug sound on the front driver/passenger side after the rear wheel hits humps. Im not sure if this sentence is correct. LOL

But the shift and slow acceleration is rather fine. I do live in the Philippines and parts is quite hard to find specially Chevy parts. I order in US and ship it via sea so it would take months for the parts to arrive.

I hope someone could give me advice on what to check, as I don't want to buy parts only to find out it was not the main issue.

NO check engine lights,

4WD?

Have you jacked the truck up and watched and listened?

Any codes?
