92 Ranger transmission fluid leak question

Hey Ranger guys and gals! I’ve got a quick question that hopefully y’all will be able to answer. So my 92 Ranger 5-Speed has a transmission fluid leak and I’m looking into getting this leak stopped. Found a bottle of “Bar’s Leaks Automatic Transmission Repair” laying around, and it says it stops leaks among other things. But I was wondering if it’s safe to use in a manual transmission, I’m figuring it is since it uses ATF, but I wanted some other opinions first before I go ahead and do it.
