Use 6 year old unopened bottle of ATF?

[Bird's_Garage]

I'm going to be replacing the radiator on my Tahoe tomorrow and just remembered I'll need some Dexron VI to replace the amount in the cooler.

I live 30 miles from a real parts store or Walmart. The best I have is Dollar General's selection (Valvoline Maxlife) or some Supertech Dexron VI that's been sitting on my shelf in my garage for about 6 years. The last option is to drive the 30 miles and get some new Dexron VI.

Which would you use? I'm really leaning toward just using the Supertech I have.

Date code looks to be 83rd day of 2017.

It's fine

I believe most companies that spec a shelf life say 5 years.

Having said that, I would use what you have. What is the factory ATF change interval - likely longer than that, and its been in a sealed container unused.

It's fine. Many cars are much older and running the original fluid

I'd use that all day.

That was my train of thought as well. 6 years in a sealed bottle vs 6, 10, 20 years in a transmission...

Use it

Shake the bottle up before using it, and then pour it in! It's fine!

I'd use it, as it was said before - many transmissions run ATF for many years where ATF goes thru work, heat cycles and contamination, so this ATF will be an improvement either way.

I wouldn't think twice, dump away!

Supertech Dex VI works great. My AW-4 / A340 which was spec'd for DexIII loves it.

Quick question, what year is the Tahoe?
If the Tahoe is older than the fluid, use it.

Also, if the Tahoe is newer than the fluid, use it.

I like that perspective!

2014, by the way, so it went in the "use it" category.

I would have no problem using it.
