BruceF Full Throttle Member Registered: 11/30/00 Posts: 5080 Loc: Long Island, NY	From http://www.corvettemechanic.com/forum/showthread.php?t=956 Quote: We have been corrected on the use of Dexron 6 in manual transmissions. You should NOT use Dexron 6 in any manual transmission. We have NOT been given any particular reason, however, the correct fluid number now is 88861800. Any vehicle that previously required DEXRON®-III for a manual transmission should now use P/N 88861800. This fluid is labeled Manual Transmission and Transfer Case Fluid.

I think my 07' Escalade's have Dexron 6 in them, it really did not seem much different in the specs of the oil as to why it could not be used in the manual. _________________________ Carl V.

rogerd Full Throttle Member Registered: 07/07/02 Posts: 774	Interesting that my stick shift K1500 specifies GM Synchromesh fluid for the 5 speed (New Venture) tranny, and Dexron III for the transfer case. That is, two quite different lubes (and very different specs)for Manual Transmission and Transfer Case. I am actually running Mobil 1 ATF in the transfer case and Royal Purple Synchromax in the 5 speed. Yes, I am a believer in synthetics but I would not buy GM's (or any other car manufacturer's, for that matter) part numbered lubes at marked up prices anyway. Let GM sell cars; let the oil companies sell oil.
