Re: GM: No Dexron VI ATF in Transfer Case
That's for you to decide. Since 2006 there has been no "official" Dexron III ATF produced.
This is the kind of crap that can happen when ATF is used in other applications. When the fluid is reformulated for better performance in automatic transmissions, a problem develops in manual transmissions and transfer cases!

Re: GM: No Dexron VI ATF in Transfer Case
SO now I am really confused. Went to my local Hummer dealer today to purchase the manual gear oil listed in the tsb for my 06 H2 and was told by both the parts and service areas that they are using DEX6 in the transfer case as the DEX3 is no longer made. When I told them that GM was advising to use the manual gear oil the parts manager went in the back and came back a few min later and told me he called GM and they said that they confirmed I should use the DEX6 in the transfer case.
Not sure what I should do now!

Re: GM: No Dexron VI ATF in Transfer Case
Dont take any chances! Put Redline High Temp ATF in the TC, as it meets DexIII specifications. Please note that it used to have the DexIII spec on it, but they had to remove it per GMs request: http://www.racerpartswholesale.com/p...ansmission_Oil
Put Redline D6 (which is spec'd for DexVI) in the tranny
http://www.racerpartswholesale.com/p...ansmission_Oil
Last time I checked, Redline had the only Full Synthetic ATF that fully met the GM DexVI specification! There may be others out now, but I am not sure. Don't listen to the BX AMSoil marketing that says there's meets this spec - it is close but does not fully meet it!
