#04-07-30-037E: Release of DEXRON-VI Automatic Transmission Fluid (ATF) - (Apr 7, 2011)
DEXRON®-VI can be used in any proportion in past model vehicles equipped with an automatic transmission/transaxle in place of DEXRON®-III (i.e. topping off the fluid in the event of a repair or fluid change). DEXRON®-VI is also compatible with any former version of DEXRON® for use in automatic transmissions/transaxles.
Clutch Friction Stability Improved 100%
Clutch Durability Due To Fluid Improved 120%
Oil Film Thickness Increased 20%
Fluid Oxidation Improved 100%
Foam/Aeration Improved 150%
Shear Stability Improved 200%
Transfer cases & manual transmission that used earlier versions of Dexron (i.e. B/W T5) are NOT advised to use Dexron VI, use Dexron III or 88861800 manual transmission / transfer case fluid.
I run Dexron VI in all my G.M auto transmissions, from a 1970 TH350 on up.
