The insurance company came back with a counter offer. I ended up taking the money and going on my own. I ordered a used tranny that comes with a 3 yr warranty for 1K including shipping. 1yr all inclusive, the final two years are parts. Unlimited mileage. They wouldn't cover the manifolds, turns out they are fine, a few of the bolts on the manifold are broken, which is why it leaks. No warranty there. They are still waiting on the driver's side pull. All said and done, its gonna cost me about 700 out of pocket, which compared to 2 or 3K for a tranny job, I am happy. Looks like it is still gonna be a few weeks. I looked at putting a 4L60 or 80E tranny in. Same housing, diesel indestructible tranny, and it would have been about 700 more. The concern we had was the computer. Don't know if a reflash would work or not with the TOD inputs.
Oh well, stickin with the 4L30E.
