2001 4 Door Grand Prix GT, 3800 V6 with 4T65E trans.
Trans History:
May 2001: Purchased new
12/06/2003, 30,026 miles: Dropped the pan, changed the filter, refilled with 7.5 qts of Mobil 1 ATF
3/25/2006 60,800 miles: Added a ATF cooler
3/26/2006 60,820 miles: Dropped the pan, changed the filter, refilled with 7.5 qts of Mobil 1 ATF
8/23/2008, 90,690 miles: Dropped the pan, changed the filter, flushed with 2.5 qts of leftover Mobil 1 ATF (DexIIIh) and 12+ qts of GM Vehicle Care Dex VI.
Blackstone's Comments: Universal averages show typical wear levels from this type of tranny after routine ATF use. This fluid was run significantly longer than that, and yet, wear displayed here is generally lower - a victorious combination. The TAN read 1.0. This is reasonably non-acidic, although a minute amount of acid is present. If that's palatable to you, no worries mate. A trace of insoluble material was found, which is perfectly acceptable. A picture of health here - nice transmission.

Seems to look OK. I did a flush this time but any reason I can't go back to 30k pan drops which is what this represents? Comments welcome.
