Shumby, let me know how the new tranny works out as I may try and talk to Sam about one. I am working a deal on a 2012 GTR right now, so if I get it I will be unloading my Z and wont need the tranny.

The AT is most definitely not sealed, and the flush methodology is clearly spelled out in the service manual. For AT's the service life with the modern fluids can be as long as 100,000 miles, which for most manufacturers that is considered the "life of the car". The oil will only last that long however if it is driven very conservatively, get the oil hot on a regular basis and it will degrade much more rapidly. Regular mountain carving, consider 30,000. If you track the car you ATF may only last 5000 miles. A transmission cooler is a worthy investment in extending the service intervals in that case.
