Type 3 ATF is commonly used in modern manual transmissions,some of them behind Vipers and Z06 Vettes.
A long time ago my daughter's car,a 70's Ford V-8 auto,started leaking red tranny oil from the front of the trans.I figured it was the front seal,pulled the transmission,replaced the seal.It still leaked red oil,must be the convertor? Not so,her well meaning boy friend had changed the oil for her,he was car dumb and used ATF by mistake unknown to me.The engine started to knock shortly afterwards,so before pulling the pan I drained the oil...RED!!!The engine was spotless inside,the bearings were also spotless,especially where the bearing material was worn to the bearing shell.
