The GL1, GL4, GL5 numbers are Gear Lube 1, 4, and 5.
I wanted to make the point that transmission leak fixer works partly by
swelling the rubber seals, using a chemical that does that same thing
that adding some brake fluid would do.
I don't recommend adding brake fluid to a tranny to fix a leak! But I
also don't recommend adding Leak Fixer for the same reason.
Changing the seals (and repairing the surface the seal rides against if
needed, as well as the bearings supporting the shaft), and replacing the
gaskets, is how to fix leaks in transmissions. You can't pour in new
seals from a bottle...it just doesn't work!
All clear now? :)
