It is the replacement from Dex III, its GM's words:

Automatic transmission fluid (ATF) is considered the life-blood of the automatic transmission. It is used to transfer power in the torque converter and provide the pressure to apply the transmission’s various clutches and bands. It also is used to clean, lubricate and cool the components of the transmission. GM’s new transmission fluid, DEXRON[ch1086]-VI, was developed to have a more consistent viscosity profile; a more consistent shift performance in extreme conditions; and less degradation over time.

Beginning with the design and development of GM’s new Hydra-Matic 6-speed rear-wheel-drive transmissions, GM Powertrain engineers determined the need for a new transmission fluid to withstand the complexity of the clutch-to-clutch transmission operation. Additionally, GM engineers identified opportunities to improve viscosity, durability, and impact on fuel economy with a new fluid.

"The development of DEXRON[ch1086]-VI is the first time an automotive company has worked so closely with petroleum and additive companies to develop a new fluid," says Roy Fewkes, driveline fluids group leader, GM Powertrain. "The result is a new fluid that significantly outperforms existing fluids in every aspect. In fact, we have had to significantly extend the length of our durability tests to fully test the fluid’s capability."

Internal GM tests have demonstrated DEXRON[ch1086]-VI to deliver more than twice the durability and stability in friction tests compared to existing fluids. It also has demonstrated superior performance in pitting, foaming, oxidation and shear stability tests.

cheers m8 looks all good then, thought i was being fleeced

have had exactly the same reply from the dealers when asking for Dex 3 which is the correct oil. They only offered  VI as they had run out of 3. I did not take them up on their offer and sort Dex 3 elsewhere. 3 is known in the omega box. 6 is not. I did not want to be the first to find out it does not work tbh. Too much guess work.

Fuchs titan 4000 rings a bell for Dex 3.

Tunnie's quote does look convincing though, but i'd stick with 3 as its known.

Most of us do it ourselves...and use the Fuchs titan 4000 


IIRC, Lizzie Zoom used GM Dex 6 in her (now crashed and written off) car.

May be worth asking how she got on with it...

I remember her's was the 1st we had heard of it in...

its now in mine fingers crossed
