I used it when I rebuild my trans last year. Yeah - it leaks very slightly, not enough to note on the floor but there is always a drop "dangling" underneath. I just wrote it off to the gasketless design of the split-case, and figured that nothing else would do any better. Every DMC I've ever been under has the same leak. The only one I've ever seen that didn't was a car with less than 2000 miles on it, the trans has probably never been hot. The fact that the case design has the lube sitting on the seam at all times is kind of an invitation to leak. I was impressed that the Hylomar that I took out was just as soft as the new stuff. Based on other experience, Silicone will eventually split and leak under these conditions, usually a lot worse. It may take longer to start though. Too bad there's no way to put a gasket in there, but due to gear tolerances you couldn't do it. That's probably why split-case (as opposed to side-loader) transmission designs are so rare.
