Hey man I read your sticky in the DIY section and I was trying to look up the service bulletin you quoted and my guy at GM says the number is no good. Any ideas if it could be under a different number?
"07- = Dex III or GM Manual Transmission/Transfer Case Fluid 88861800 (88861801 Canada) as per "GM Document ID #1897292".
07.5+ = Dex VI Automatic Transmission Fluid
From the factory, these t-cases come filled with automatic transmission fluid. Due to licensing changes around 2006 regarding Dexron III, GM released a service bulletin (Document ID #1897292) recommending the use of manual transmission fluid, in place of Dex III. This manual transmission fluid is: GM Manual Transmission/Transfer Case Fluid 88861800 (88861801 Canada). "
