Downshifting in a 793
Lots of people send it photos to this blog. (Thank you!). Normally, I check them to see if I already have them in my collection, and then put them into
the rotation. Sometimes, the photos are so amazing that I just have to put
them up on the site right away.

That is awesome. I'm glad I wasn't in the engine bay at the time, it looks like an anti-tank mine went off in there.
The story's a load of BS. The tranny won't downshift from 6th to 1st like that.
Looks like the floor of a slaughter house!
Ref the comment above. Not necessarily total BS. There WAS an electronic issue where transmissions would experience a 5th or 6th speed to 1st speed downshift around the 1999-2000 frame. However although I personally saw a few engines that had this problem none of them ever grenaded like this one, the worst that happened was a single connecting rod through the side of the block.
See here if you want more discussion on the subject.....

Sunrise dam 793 after a midlife??
There was an engine which let go in similar fashion after a rag (which was left in the sump) blocked the oil pickup
Not sure is these are from the same incident though
looks like an oil pan failure to me.....a failure to catch all the broken parts!!
The last photo with the guy holding a Pepsi can is a Liebherr Haul truck, not a CAT.
