The other option is if someone wants to swap whole Carriers. This is a steptronic carrier with the shorter final gear. I've been told by a couple of people (including the Berk race team) that the Carriers swap directly from Manual to Steptronic.
Option two, I'd be looking for the other party to cover Labor for Carrier Swaps +$cash. (Carrier Swap also saves both parties on Diff Oil, though a diff oil change on my carrier should probably happen in the next 6 months/5,000 miles)
