Part 2: Transmissiom fluid color
This might be the dirtiest fluid I have seen. New stuff was red.

Passenger bottom of control arm is also covered in oil. Not a drip or leak but it's just been like that since I got the car.
is it just me or does it not feel kind of criminal how often a flight will start checking carry on bags half way through boarding even though they were fully aware of how many seats they sold that come with overhead space? like its not a mysterious thing that just happens, they sell a certain amount with carry on space and they cost extra. It really just feels like they sell more than they know they can handle and we take the hit.
Thankyou to those who responded previously and here is a video of the car revving slightly. ( I want to add that the car has spark plugs that are were for the tune it previously had, roughly a 50hp difference. But it is currently on the stock ECU. Could that possibly be the cause of the noise?) Also it has 5w30 in it currently but I have heard people reccomend 5w40. Why?
I want to preface this by saying I am not very mechanically inclined.
This video shows how this 2004 95 arc sounds idling. If anyone with some better ears can give it a listen and let me know if everything sounds right or if there's something I should be worried about please let me know.
