Well, you have to weigh the cost of the transmission (or whatever its' determined to be) vs. the overall condition of the van, vs. the cost of getting a new replacement vehicle (including title, tax, etc). I know this is nothing you don't already know. In other words, it's going to end up being a personal choice none of us can make. I've been there before. I've gone both ways. Sometimes you just bite the bullet and repair the thing, and sometimes you're just tired of owning it and ready to move on. Hope your insurance settlement covers whichever path you take.
