02 transmission leak
So I was driving home and noticed a check engine light on so I pulled over noticed good amount of tranny fluid was leaking so I got to autoZone checked the levels they were low as I assumed and put to quarts in to get home it Also pulled a code and it was transmission temp sensor low voltage I’m confused on where this part is and how to fix it pulled wheel and shroud still. Can’t find the source yet

No exact answer, but a few things to note:
1) proper transmission fluid level is checked with the car running and warm (not hot), and only accurately gauged if sitting for a few hours as the drip and splash from the fill tube skews the read otherwise (makes it look too full/more full than it is). Bottom line: tricky to read accurately and fools most mechanics. Check it in the am after starting and before driving - best way to get accurate reading.
2) Most common leak source IME is the 1/2 shaft seals on the inboard ends of the axles. Had any work done lately? PS leak that makes you think it is the transmission is far more common. Same fluid, and can be hard to trace to the source.
3) On all other transmission I know, the temp sensor is inside the transmission usually adjacent to the valve body and solenoids as that is the easiest point to wire; remove the lower pan to access. You do not need to pull a wheel or fender liner to get at it; it is from below.
4) This transmission is very robust and more tolerant of getting a little low on fluid than many others, but don't keep driving it if it is leaking and push your luck too far. Otherwise you will need a replacement transmission or complete rebuild.
