Message-ID: <1189@shark.UUCP> Date: Mon, 10-Dec-84 14:02:44 EST Article-I.D.: shark.1189 Posted: Mon Dec 10 14:02:44 1984 Date-Received: Wed, 12-Dec-84 05:17:39 EST References: <155@decwrl.UUCP> Organization: Tektronix, Wilsonville OR Lines: 11 Some cars do use motor oil in the transmission/differential. I had a 77 Honda Civic that called for 10-30 oil in the trans. I put some syntheticc oil in hoping to reduce wear, etc. The transmission became hard to shift and the gears would grind, especially between first and second. I put standard 10-30 back in and the problem went away. Turns out some friction is required to make the synchro rings work properly. The synthetic oil reduced friction to a point where the rings did not work. Dave Williams Tektronix, Inc. ECS
