2003 pontiac aztek pops and sputters when i try to drive it

I do not know what you are looking at in the manual, but you probably heard a horrible noise when you put it into park, as the parking pawl tries to hold the car in place. Thist usually does not harm the transaxle. If the engine won't start then something else happened, perhaps the neutral safety switch was damaged or knocked out of adjustment. You might try to move the shifter back and forth and then back into park and then try to restart. If that doesn't work try to put the car in neutral to start. If you must have the car towed somewhere the repair should not be expensive, just have them reset the neutral safety switch.

sounds like you have a vacum leak . pop the hood and look for hoses that look like they are disconected or broken . most common are right above the throtle body

the wiring on the shifter is bad. this happened to me as well. It cost about $50 to fix.
