I have a 2005 Chevy Trailblazer Ext LS 4.2l v6 and I need to do some maintenance on it but I'm not the best with fixing cars and I don't know if I'd save money in these scenarios or if I should let the shop handle it but question 1 is

1) I need to change the spark plugs. Is that a costly and difficult procedure? I've never done that before.

and 2) I bought my car @ 150k miles and I'm at 175k now and I feel like I might need the trans. fluid changed but idk how to check if I do and I also don't know if its something I should do myself or let the shop do.

Any advice would be helpful I don't have to much money to spend, I know the shop is gunna want probably $500-800 just to do one of those if not both. I have rent and my car insurance coming up and that's gunna hurt my wallet.

I have found this video for you about your transmission fluid as I wasn't sure myself

however I do know that changing your spark plugs is an easy enough job, there any many tutorials and help threads on the internet that will save me a lot of time explaining and also save you so some bucks!

I wasn't able to follow the video clearly, so basically is he saying that you leave the motor running for a few minutes and after its warmed up you check the dip stick on the trans. fluid? what color is it supposed to be and how do I know if its low or anything.

is it an automatic? if so it should be a pinky colour (ish) if its not very pink and more brown then it should be changed. (there are many images online) <- have a look because there will be scales of how bad it really is etc and on your dip gauge you should have a measurement on the actual stick its self? make sure you properly wipe the gauge before putting it back in to get an accurate reading

Alright once I leave work and go to my car I'll check before leaving. I hope its good to go still. I really got money problems rn and its pretty shitty. I can't buy another car or even get a loan if my shit blows up.

This is correct.

There should be a low/min and a high/max line on the stick. Make sure it is within these.

I wouldn't worry about it to much, what has made you think about it? has your car started running differently or something?

Starting with trans fluid, it's generally a light pink / amber color, once you drive somewhere and the vehicle is at operating temp, check the dipstick to see if the level is fine, the color of it, and smell it. If the level and color is fine but smells burnt, it needs to be changed. I personally would not recommend a novice to change trans fluid as it usually requires you to drop the trans pan which means you need to make another gasket and tighten all the bolts in the right order and at the right torque when you put it back on. If you do do it yourself, usually there is a magnet in the pan and there will be metal shavings on it. This is normal. Sometimes you might find a plug (usually yellow), this is also normal. They put that in from the factory so nothing could get into the trans before they put the dipstick in it. Just take it out and it will be fine.

Spark plugs can be tricky, if you don't have a torque wrench I would not do it. If you do them yourself, do one at a time. Each spark plug has its own wire and if you mix up the wires the vehicle will never run right. If the vehicle is rusty, the job will be a PITA. A lot of times the spark plug will break making it impossible for someone who's not knowledgeable to do it. Sometimes things can be in the way, in one of my old trucks there was a fuel or oil rail that you had to take off to do the passenger side spark plugs. If you have a torque wrench and the vehicle isn't too rusty, I'd look up the torque specs and see if the plugs are easy to get to. If they are I'd try it and save yourself some money.

Do you have a junk yard around? If you do, try to change the spark plugs / drop the trans pan on one of those vehicles and see if it's something you're comfortable doing to your own vehicle.

On top of what he said i would do a complete flush mostly likely the previous owner(s) didnt. Also as long as you how to set the gaps on the spark plugs and have the means to do so, then go right ahead

Spark plugs are something you can do yourself to be honest, the torque setting isn't high for spark plugs, it usually is just 1 or 2 nips of the wrench and it's all good. Spark plugs usually come pre-gapped if they are for your exact engine that is, otherwise you would need to adjust them with a feeler gauge.

As 002 said, it is preferred to have a torque wrench but as long as they are not too tight or too loose, they're fine. Over tightening could lead to your spark plug being thread locked and metal shavings going into the cylinder, but I mean it's pretty hard to cause that to be honest.

But yes, I don't see why you can't do spark plugs yourself, it's worth a shot.

As for the transmission fluid, that's a little more difficult.
