Valvoline Synthetic DexVI for '17 Silverado & '17 Tahoe 6L80's?? Recommendations please..

[Islandvic]

I have a 17 Silverado (62k) and 17 Tahoe (78k), both with 5.3/6L80 and in mechanically sound condition.

Looking at DEX VI ATF recommendations. I can easily source Valvoline synthetic Dex VI for $26-$30/gal.

A little history.... Silverado has the upgraded GM TBV and Tahoe getting the Superior Solutions TBV kit installed this weekend. Silverado had trans filter replaced, magnet inspected (no metal shavings) and fluid flushed out by dealer under warranty around 30k miles, while the Tahoe received a basic pan drop filter/fluid change around 70k miles (no metal shavings on magnet). Silverado occasionally tows a 6000lb travel trailer.

I plan on buying off Amazon a fluid extractor with both the manual and pneumatic pump so I can easily change out the fluids in our vehicles. Both the Silverado and Tahoe will first get another pan drop so I can change the filter, inspect for metal shavings, and then add another magnet or 2 to the pan.

Then I plan on either performing multiple drain/refills with fluid extractor or by disconnecting a cooler line to drain.

I am looking for anyone's experience/preference regarding the brand of Dex VI they used in their 6L80 and if anyone has used Valvoline syn Dex VI in the blue jugs.

Eventually I want to upgrade the torque converters to heavy duty billet units on both the Silverado and Tahoe because I like keeping vehicles that are paid off

Thank you for your input and suggestions !!

GM uses AC Delco Dexron VI, AC Delco is OEM.

Any officially licensed Dexron VI is going to perform about the same.

The Dexron VI license requires at least a semi synthetic base oil to meet the oxidation and other performance characteristics and specific, approved additive packages, so the Valvoline with it's synthetic base will be as good or better than anything else you can get for it.

I believe that SuperTech has a licensed Dexron VI; that would be my choice for that spec. Probably the least cost DexVI you'll find, especially if multiple drain/fill cycles are your goal.

Any license product is fine. Dont over think it.

Our 2017 Tahoe was mainly on the blue bottle Valvoline D6 - but on the last two swaps used the newer Valvoline Extended Performance …
Put in a B&M drain plug and only pull the pan for a filter …
(fluid yearly and filter at 3 years) …

My 6L90 is full of red and blue jug Valvoline Dex-VI

Just finished (3) extractor drain & fills on my '14 Sierra with a 6l80 at 87k miles. Valvoline Maxlife for the win. I didn't realize the shifts were getting a bit rough, now, they are smooth.

The valvolone dex vi that you can source is good fluid. I have used in the past and the trans worked perfectly

 

[slacktide_bitog]

Any licensed Dexron VI is acceptable. The cheapest licensed Dexron VI will be fine.

I would save your money on the extractor unless you really need it, and buy a new pan with drain plug for each truck. It makes service so fast and easy.
