The bore that these rings ride in, is NOT as smooth as every other transmission that uses these PTF rings that I have seen and It's not always a slipped CDF drum sleeve as much as it is worn rings. These rings move back and forth within the end clearance tolerance of the 10R80 and wears down the OD or the rings from riding in such a ruff bore. I have not tried smoothing the bore of the CDF sleeve with a flapper wheel, but if it was my own transmission and not a warrantee job, I would give it a go, including the stator and hub shafts.
The small out put shaft sealing ring requires the 6r140 input shaft sealing ring tool
The distorted sealing ring is one of the reasons why 10r80 f drum failed so easily.
It is to bad nobody has taught you how to use a ring installer properly.
Thank you Sir!
You bet!
Is there a more universal tool for other transmissions similar to the one for 10R80? maybe for ZF 8HP ..?
Yes there are universal tools for most transmissions you can check with your local tool supplier.
Thanks. Have a nice day
