    they've been advertising it forever in the popular automotive magazines. Its a redesigned 4L80e. Not sure what all they've done internally to make it 6 speed. If they added more parts internally, that means they had to weaken other parts to get an additional planetary set in there. I've hear gossip that they lock two sets of clutches together to make the additional gearing. Not too sure how all it works but built by a decent builder.
