[Aqua Blue RS/SS]

Yep that’s exactly right. Your L99/6L80 wasn’t built with a dipstick from the factory. That plug I posted is in place of the dipstick and is actually the fill plug. To check the fluid you have to get the car up in the air and level. With the engine running, transmission in park, and up to temp per a scan tool, there’s a bolt that looks like a drain plug in the back of the pan that you remove. If you remove the bolt and get no fluid it’s low. If you pull the bolt and get a slow dribble it’s good. If you pull the bolt and it pours out it’s over full, let it run until it’s a slow dribble then it’s good. It’s all incredibly stupid. I can’t decide if I believe more that GM was being cheap or trying to force people to the dealer for service. Mine still with a factory fill, no leaks and 10,000 miles was close to a qt low. That’s irritating, with no easy way to check it. Mind you the fill plug is only a few inches from the exhaust, and fluid has to be pumped in without a dipstick.

I use those wipes from time to time, they do pretty good. I think next time around I’m going play around with sealers before I wax. I’ve never messed with them before but want to try it out.
