Using pywallet, dump your wallet
You will see lots of things including your keys, and transactions (At the bottom, that contains tx something)
I think that if you search (Ctrl-F) '3ea177ce0db93b9bbbdc2286f5ca08e038a364db704205250d253d704a67d6a1' in the pywallet web page it will find it
Then you have the txid

BTW isn't 3ea177ce0db93b9bbbdc2286f5ca08e038a364db704205250d253d704a67d6a1 the txid?
