Hi everyone, i have a Chevrolet Captiva, the tranny uses DEXRON VI compliant ATF, it is ok to top off with DEXRON III? Im asking this since where i live its hard to find DEXRON VI, and i need to top off a little. Thanks!

May not hurt, but probably not a good idea; Dexron III is not "forward compatible" with Dexron VI.

Perhaps more important: Why do you need to top off ATF in a vehicle as new as a Captiva?

I would say any possible harm (if there is any) that would come by topping off with DEX III is far outweighed by the harm of running low ATF levels.

Get the right stuff.
How far away from civilization could you possibly be?

How low could you be?

Give your old Dex to a friend who can use it.

Are we to assume you have leaks?

Get a new gasket and seals installed and you shouldn't need to top off.

What ATF products do you have access to in Ecuador?

For sure.

Can you order Dexron 6 ? Can you do Amazon or one of the other internet vendors ?

Is there a GM dealer close enough to get Dexron 6 , there ?

I agree , if you have a leak , get it fixed & make sure the mechanic uses Dexron 6 . How much are you needing , any way ?

Just found this with a google search ;

Best of luck to you , :-)

What is the reason it runs low? Was there a leak or did you replace the radiator? I'll be more concerned about why it runs low.

Do not top off with Dexron III.

The viscosity profile is completely different, as are the friction materials and additives in the formulas. Use a Dexron VI fluid.

Are you checking the fluid level when the tranny is at full operating temperature, engine running and on level ground? This could show a lower level if temp is not warm enough and running.
