I am having to replace the transmission pan on my Lexus GS300. Auto parts stores sell gaskets and Lexus sells a pink gooey Toyota liquid gasket material. Which product would you use? I'm concerned about how big a bead of that Toyota stuff to lay down.
Sealing Transmission Pan on Lexus GS300

Use the pink FIPG. 3/16" bead is enough. Use a big flat blade screwdriver to carve out the old FIPG in the pan bolt holes

Pay attention to the part about getting the surfaces absolutely clean and dry.
XOXOXO I can do this! Thanks!

Just be careful that transmission fluid doesn't run down across the sealing surfaces and interfere with the FPG making a good bond. It helps to let the old fluid drain as long as possible (overnight or more) if you can. Then a trick I use is to stuff a couple of paper towels up into the areas of the transmission where most of the oil still seems to be dripping (but not up so high or wrapped around anything such that you can't remove them later). The paper towels will help to wick out additional fluid, and you can go ahead and apply the FPG to the pan or transmission surface as directed. Just as you are ready to put the pan up against the transmission, carefully pull out the paper towels making sure you don't tear them or leave anything behind. The towels will help to make sure you have enough time to carefully place the pan in place. Once the mating surfaces have made contact you are good to go ahead and install the bolts.
Now, if the rain would stop and it would stay in the 60's...
The car is on jacks outside in driveway and has been out there since last Wed blocking one side of my garage (don't ask) and my son's Prelude is in the other side (where my wife usually parks the GS300) waiting for OEM Honda Prelude brake pads to arrive from California via FedEx. We are down to the 4runner and the LS400. Ain't that something? 5 cars in your stable with 3 "out of commission" simultaneously. What started out as something so simple....This is not good with ADHD....LOL

On a sunny, dry day take an afternoon and take your time DIY.
Seems the sealants are used as a cost saving measure, but at the same time the Japanese mfgs use very good sealants that go for decades.
If I could use a synthetic gasket (not cork!) that would be my choice due to it being more forgiving.
As others have mentioned, a sealant is only as good as the prep work and the underside of a car is the last place I can do any sort of precision cleaning. Sealants make perfect sense on the assembly line where everything is clean and the transmissions are on articulating mounts so you can apply the stuff in a downward fashion (or nowadays they probably have a robotic arm do it in a very precise pattern).
My old F150 had the 4R70W and it came from the factory with a synthetic gasket for the oil pan. Lasted the entire life of the truck and never leaked.

Do you need to use a liquid gasket material? I had a 98 Sienna and I only used a gasket(rubber or cork) when changing the tranny filter and cleaning the pan.
