I can't speak for FASS but I know I've got a converter in my truck that is purple from having zero fluid and getting so hot it cooked every clutch lining. I sent it in and was able to work something out. Please please please take that with a grain of salt as I'm a tier 2 dealer there.Their third party "comp generating" service didn't give very good comps, so we are in the first round of working that out. Sounds like they are counting on me being in a hurry for the check. I imagine we are all going to have to agree on a value first before that offer gets given. The truck is in Martinsville VA if someone from forum land is seriously interested. If so, I'd like the 1/2" drive craftsman tools (old usa forged stuff) back from under the back seat ashes. All my other metric tools are in the dumpster they loaded the camper remnants into on scene.
One comp was a twice wrecked, rusty, 400k mile GMT900. The other was a LS trim dually without a bumper, that was a theft recovery 14 years ago. I responded back with actual comps. I illustrated that everything within 500 miles <$15k has obvious rust issues, that mine didn't have. Anything reasonably comparable is >$22k.
Tongue in cheek…Will goerend warranty the converter? FASS lifetime warranty?
With that said, I know the converter itself could, at minimum, be rebuilt if it needed to be. If the concern is warranty for the second owner I know that one I can easily accomplish with a receipt and an explanation/email to Goerend.
