Guess I'm still too 'old school' when it comes to manuals.
Well, people here call me old school Rodney because I like and drive an old Jeep and wear Jeans and boots and use to work with my hands... so if I am old school, what are you? LOL just teasing you bud, when I was an apprentice we learned that ATF is for auto trannies only and that filling a manual with ATF would destroy the tranny. But I've read that in some racing applications they used ATF in manuals decades ago. And Daimler uses ATF since about 20 years in their trannies depending on application and usage and VW used it since the mid 80s, no idea if they still do.
