Quick questions with pics

Hi,

I'm going to replace coolant and transmission fluid on my 95 Avalon for the first time (on my own) either this weekend or the next. I just have a few questions before I proceed.

Is this the transmission plug?



As for the coolant replacement, I've located the radiator drain petcock but I wasn't able to find the engine drain plug. Is it possible to do a clean replacement without removing the engine drain plug?

While I as underneath the car, I took the following pic:



What is the circled connector for?

the first pic is the trans plug, second i dunno. lol on the trans can u just "drain" the fluid. but i prefer to get and "Screen and gasket" and remove the transmission pan and relpace the screen and gasket and clean the inside of the pan and check to see how much metel and crap the magents have caught.

I think that connector in the second pic is for the outside temperature sensor

What size is the transmission drain plug? Is it 14mm hex?

Mine are 10mm. The engine oil drain is 14.
