No way, Jose. Not worth the risk as them thar fancy trannys can be a little bit spendy.
There's no real alternative to the Pento fluid either. At one time redline said they might consider making a DSG fluid but they or anyone else has not stepped up as far as I know.
It's a really light tranny fluid (I think 11 cST as I remember). WJdell has a VOA of it on tdiclub.
