Acceleration Issues

So....I went for a drive a few nights ago with my wife. I have an 05 GT Auto. I usually drop it into 3 and shift up to D when I pass someone. I did this the other night and a few minutes later when I take off from a stop- I accelerate slowly and then all of a sudden my car starts this kind of "Jumping". Like I was giving it more throttle than I actually was. This is the second time this has happened. I wanted some opinions before I go to a shop. Do you think it could be a throttle or a transmission issue? Thanks.

My 09 5-speed does this in first gear a lot and Idk why. I've tried everything and can't figure it out.

My car has that jumping/jerkiness in 1st gear sometimes (88 mustang 5-speed) I was told it was probably due to my unmodified state + having 4.10s. With an auto and only 3.55s I wouldn't say that was the issue, but just something to keep in mind. Your rear gear ratio is probably amplifying the problem, otherwise you might not even notice it.

I have 3.31's. But I am wondering if it is my TPS, since it only happens when I give it gas.

And it very rarely happens. But I just want to address it before it gets worse.
