i have herd the stories that one you swap the oil from an old machine over to synthetic there is a potential for many porblems, one of which is leaking. I switched my tranny fluid to a full synthetic and about 2 months later it started to leak....before it was bone dry with the facotry stuff. my question is if i swap back to the original tranny fluid will it stop leaking? or did i ruin something and now have to replace the seals...................?

 

I don't think you "ruined" anything. I've been told what happens is gum/varnish deposits build up on the shafts around the seals and prevents them from leaking. When you go to synthetic, because it is thinner and more detergent, it melts those deposits and you get a leak. Switching back at that point won't help.

I put synthetic in the T-5 in my Mustang and it was very hard to shift. That problem went away once I switched back to dino.
