Theres a thread in the EG forum, and everyone LS tranny seems to be marked S80, and Tom hasnt seen a Y80 LS tranny before. but sure enough the tranny that came on my LS is Y80, but I dont have a VIN plate so I dunno if its OEM or what. anyways what does everyones LS tranny say?

 

i used to have a y80 tranny in my 94, but almost all i've seen have been s80
