5 quick operation and Maintenance Qs

I tried to do a "like new" test and drive the car about 55-60, just so the needle was on the bright beam indicator and see if it helped ever. It didn't. The only time you see a cool down is when leaving the freeway, like on the video.

I switched to a #57, readjusted the idle, and my gas gauge is not dropping as fast visibly - but it drives the same, but I won't know for sure till I read it at my marker later in the week, and then re-evaluate with another tank of gas. Something of note, is that the temp gauge is back at 180, not like 190 as before while in town. This may just be me being hopeful but it is pretty consistent.

It's been a while with the new radiator, and it has not leaked yet, and seems to function. The transmission cooler is built in, so I'd have to find an alternative cooler to try the test. I know they're inexpensive, but I may have to wait to try it. The transmission seems fine, except when in a parking lot or going really slow - you push the gas, then all the sudden someone backs out of a parking spot, so you let off. The transmission goes into 1st I'm assuming, since i believe it starts moving in 2nd on the torqueflite? I could be wrong. When the downshift occurs (only at this low speed) there is a metal pop that occurs. The car does not move, or lurch, it just makes a loud sound. It does not occur at any other time.
