Gas Pedal Wiggle

[Jansen]

I'm a newbie and I have a question. I bought a 2004 GMC Sierra last week (Z71,4x4,ext cab, 5.3L, marine blue) and may have an issue with it. When I shift from park to drive and shift from 1st to 2nd I get a vibe/wiggle in the gas pedal. This doesn't happen at any other time. If I stop, and start again it will not do it. It will only do it once I have started the truck, shifted to drive, and shift from 1 to 2. I"ve heard this could be an ABS break check with TSB #03-07-30-032. Is there anything else I need to look at? Other than that it is a great truck.

let me clarify, it is when the tranny shifts from 1 to 2 not me shifting.
