I once was able to reduce synchro problems in a manual transmission by switching to a thinner oil. But I suspect the OEM oil "weight" in the Insight is already about as thin as it gets.

Have you tried double-clutching when going to 2nd? That's generally another way to avoid the crunchy sounds.

Wow - 600 bucks for the oil pan! Is there no other fix available? Have you searched around on insightcentral.net?
