If it is a 2FA wallet... you're not going to be able to spend them anyway, as TrustedCoin does not support BCC... so you won't be able to get them to sign any transactions you make.
To use your Electrum 2FA wallet on Electron Cash, you need to restore in Electron Cash using your 2FA seed and select "DISABLE" when prompted during the restore process:
That should enable you to then spend your BCC from Electron Cash (as it restores 2 master private keys onto your PC, so you can sign the transactions with 2 keys without needing TrustedCoin).
If it is showing up as unconfirmed, and showing the BTC transfer, then it sounds like Electron Cash is currently connected to BTC network and not the BCC network... Go into the network settings and see what server it is connected to.
If the blockchain you're connected to shows a number much higher than: 478818 (like ~479750), then you are connected to BTC network.
I can start Electron Cash 2.9.2 with a server specified at the command line, and it will show the correct BCC balance but I can't send.
"your client produced a transaction that is not acceptable to the network anymore"
Are you using a 2FA (or MultiSig) wallet by any chance? It sounds like the transaction is not being signed correctly... so the network is rejecting it.
