Those gears are not synchronized (second and third are) and after the gear oil is heated up by driving, it gets thinner and gears are still spinning as you attempt the shift. I would consider that normal. All my 4 speed trannys do that (none are synchronized in first and reverse).
I cannot explain the difference due to your change in oil. Perhaps it is because it is summer in Michigan now and the oil is thinner?
