I replaced my transmission oil today with Napa GL-1 80-90 wt /mineral/gear oil, drove it around town some, transmission grinds easier than before, lots of double clutching, not sure which transmission I have, 3 speed behind an 8BA. Seemed like it shifted better with Coastal 80/90 GL4 or 5. Any thoughts?
