View Full Version : '06 V6 transmission service cost?

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?

The biggest differance is that the newer vehicles require Dextron VI transmission fluid. Dextron VI is synthetic (so guess what, it is quite a bit more expensive than the old stuff).
