How much pressure is that shim washer supposed to add??? If it's a lot, I can see how leaving it out may have caused or allowed a pre-mature failure to occure BUT I can't imagine it would happened all at once like that. I mean, it's kinda strange that had been holding fine, was holding fine at the time then just completely fried all of a sudden. Seems there would have been slippage at some point leading up to the failure as parts (clutches) deteriorated rather than just a sudden failure like that supposedly caused by lack of pressure??? Like I said, my rational (and I know next to nothing about these transmissions) is that the parts would have failed slowly if the only thing wrong was the lack of pressure. This seems like something gave way suddenly. Crazy. I do feel for you.
FWIW, my SCIII has held up great thus far. It was built by Eric Merchant. I failed to maintain my u-joints properly and now have a cracked tailhousing on my transmission that leaked all the fluid out as a result. Hopefully the damage is minimal and simply replacing the clutch packs will be the most I have to do (aside from a new tailhousing case
) to get it back on the road for 30K more miles of 500rwhp beating.
