If you want to assume they are fine and don't want to check I'm okay with that. When you troubleshoot you somtimes need to do some clue gathering. Since you don't want to, not much I can do.
Good Luck.

When you are trying to accelerate, are the engine rpms going up and you are not gaining speed. Or the rpms are just not going up?

This is important so I understand you.

Have you ever felt a transmission slip?
The rpms or engine idle goes up but you don't move faster.

If you press on the accelerator and it is a rough feeling and you may or may not go faster.

That weird gurgling noise, is it like shaking marbles in a can noise?

the noise is like a grinding noise when i accerate around 30-35mph then it stops, then at 50-55 its fights to go above that, it will make a hard rev sound if itry to push on gas around 50-55 mph, then if i let off the gas a little then try again it moves a little closer to 60mph but not much

does it make a difference if it is cold (setting 8hrs) or after driving for 20 minutes or more? has the pcm software ever been updated? is there a label under the hood like this?

At this point, that is where I would start, is update the software.

took it to speedy transmissions to get a free inspection. an 1hr and half later they call and tell me, that 2nd gear is gone, it jumps from 1st to 3rd. its going to cost me in between $1200-1400 to get it rebuilt......great!!!!!!. thank u so much for all your help.

Suggested Repair

Have the automatic transmission rebuilt or repaired. A transmission shop inspection found second gear failed, so the transmission jumps from first to third. Confirm fluid level and condition, and consider a PCM software update only after the gear failure is addressed.

Conversation Summary

A 2001 Dodge Neon accelerated poorly even after new spark plugs and wires, with a grinding noise around 30-35 mph and hard revving that limited speed near 50-55 mph. Fluid levels were confirmed normal. The expert asked whether engine speed rose without a matching increase in road speed, suggesting possible transmission slip, and recommended checking for a PCM software update. A transmission shop later found second gear failed, with the transmission jumping from first to third, and quoted a rebuild.
