TRNW-2: 6R80, rebuild minimums

[Healy Powertrain]

I had one with a cracked E-Drum (4-5-6). It was on a Raptor though, maybe from heavy use. Looking at the design of that drum (Thin Stamped Steel with Friction welded Input Shaft) I consider that too weak for heavy use.From now on Raptors and F250's get a new OEM drum, cracked or not.

Theyre not that expensive, 300-something

This trans only had tcc shudder, no codes. 200k, looks like original fluid. just tearing into it. pan very clean for mileage and no maintenance. Also hearing only borg clutches in 456. ANy other 6r80 experience greatly appreciated. Thank you
