DEXRON®-VI ATF
General Motors Powertrain has recently upgraded to DEXRON®-VI ATF with the start of 2006 vehicle production.
Current and prior models that had used DEXRON®-III must now only use DEXRON®-VI.
All 2006 and future models that use DEXRON®-VI are to be serviced with DEXRON®-VI fluid only.
DEXRON®-VI is an improvement over DEXRON®-III in the following areas:
DEXRON®-VI
Extended Factory Fill For Life---160,000 km (100,000 mi) For Cars and Light Duty Trucks*---80,000 km (50,000 mi) (Severe Use) For Cars and Light Duty Trucks*
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%
* These ATF change intervals remain the same as DEXRON®-III for the time being.
I mean smoother. I have a bad input speed sensor (code P056/OBD I) and the shifting is more firm then stock with that problem. The Dexron VI made it shift noticeably smoother.Hey clarkz71, when you say shifting was improved, do you mean smoother or more aggresively? Also could we you use the B&M transmission fluid for firmer shifts in our trannies?
I don't know if my clutch packs were doing anything, but if you know cadillacswhat you are actually feeling is the fact that the older fluid has been allowing the cluch packs to shudder but at high frequency so the new stuff has a friction modifier to help with that and its a synthetic too.

You can do that J, but it's very easy to pull the top line, attach a fitting/hose and purge the transaxle completely.I read that to say that the DEXRON-VI is fully compatible with DEXON-III, meaning that when doing a normal drain/fill service on a DEXRON-III car, no additional steps are necessary (like trying to pump out the old fluid, etc), correct? Simply drain as much DEXRON-III as you can, and fill with a like amount of DEXRON-VI?
