4 speed ka-booom !

OK what's this whole using Vaseline thing all about? I figured I didn't need to order transmission grease and have it sent all across the United States and I could go down to the local parts store and get it. well I learned that lesson, they don't have it not nobody. So I bought a jar of Vaseline and just in case someone is reading this thread and wondering where you get it, it's with the lip gloss and lip balm and all that stuff. I had to search for it in the grocery store for a while till I found it. Is it for surely soluble in transmission fluid or actually in gear oil that's what I intend to use? And I've already heard about the colder temperatures to make it more pliable or sticky. I plan to use it outdoors on my patio and it's starting to get a little cooler here. Thank you.....
