4l60E Rear planet bearing gone/splines seperated Any one have the rear planet torington bearing desinegrate, as in bearing not there anymore reduced to lots of fine particals in the pan gone? Then looks like the sun gear popped the splined portion of the planet off. No forward gears, only had reverse. Any Ideas as to cause?

Nice pic bro, I've seen some nasty planet failures but that one might take the cake. Lack of lube is always first to mind when I hear of a planet failure, but I really don't see much of any lube issues on 60Es. I've actually had a run of several forward planet captured bearing failures in the last two weeks. One being a 53,000 mile CB
None of them showed signs of losing lube oil.I've also seen several rear ring gears split in two for no reason on stock 60Es. Quality control?
brybe- if the planet has been turned black/blue... most likely lube failure. Be sure to HOTFLUSH and flowcheck cooler or replace if no one locally has a HOTFLUSH cooler flusher. Standard overhual.
If no signs of overheating... most likely poor quality control. Standard overhaul. Good luck!
