Check to see color of fluid and what it smells like: if its brown and smell burnt it no for popping, sounds like timing is off/poss timing chain jumped.

What causes my 2003 pontiac bonneville to **** when it shifts from 1st gear to 2nd gear. and when it gets warmed up after 20 minutes to 30 minutes driving it acts as if it do not want shift gear or not...

Honestly, it sounds like your transmission is starting to go bad, With the cars I have had that hesitate to switch gears, the transmission went out soon afterwards. Have you made sure to check the fluid levels?

Also, check the level and color of the transmission fluid. It should be red/pink in color without much discoloration in it. And the level should be at the designated line on the dipstick.
