This bulletin is being updated with the 2007 model year. Please discard Corporate Bulletin Number 04-07-30-037A (Section 07 - Transmission/Transaxle).
General Motors Powertrain has recently upgraded to DEXRON(R)-VI ATF with the start of 2006 vehicle production.
Only 2005 and prior models that currently use DEXRON(R)-III may use DEXRON(R)-VI as a replacement.
All 2006 and future models that use DEXRON(R)-VI are to be serviced with DEXRON(R)-VI fluid only.
DEXRON(R)-VI is an improvement over DEXRON(R)-III in the areas shown.
2006-2007 Transmission Fill and Cooler Flushing
Some new applications of the 6L80 six speed transmission will require the use of J 45096 - Flushing and Flow Tester to accomplish transmission fluid fill. It is highly recommended that the clean oil reserve of the machine be purged of DEXRON(R)-III and filled with DEXRON(R)-VI.
