Anyone familiar with this type of galling, or how it could be happening? This is the second Piston Retainer within 5000 miles and a third with less than 100 miles just installed and wearing again.
This began after the transmission was upgraded with an after market HD RV Billet T/C and a shift kit with billet servo and accumulator (which I don’t believe is the cause). The mechanic did completely disassemble and reassemble the transmission only to inspect it (I believe this may be the cause).
I have just completed an entire self rebuild, (all clearance specs are to either the ATSG guide or Red Eagle Power Pak Spec’s) reinstalled the transmission and removed the pan to make some pressure adjustments and once again I have aluminum shavings and aluminum metal flaking in the ATF again with less than 100 miles on it.
I was very meticulous and anal about everything being to spec and I found no evidence of wear or damage to any of the internal hard parts except the ones pictured below.
... ... ... ... ... ... ... Also See photo bucket link below!

The current shavings/flaking are very thin and floatable in the fluid unlike the type of shavings found when the other two retainers went bad which was thicker and accumulated in the pan.
Is this a common problem because of High Horse Power and Torque??
Thanks for any input or idea’s
