Today I took my 06 STS 3.6 in to the dealer for a few small fixes under warranty, and asked about transmission service. I have about 43000 miles on it and like to stay ahead on maintenance. The service writer clearly didn't want to do this ("you shouldn't do that until 100,000 miles"). He proceeded to say it would cost about $250! I declined, but is this typical? Is there anything so special about this transmission that it would cost so much?
