Best Fluid type on 4L60E
#1
![Default](https://ls1tech.com/forums/images/icons/icon1.gif)
I got a quick question on our wonderful 4L60E here, what kind of fluid do you guys use?
I have seen some people swear by synthetic and others not, I'm not quite sure which one to pick and I would like to swap out the transmission fluid.
The car has about 114k miles (mainly highway) and I'm not sure if the guy ever changed the fluid... :/ Shifts perfectly tho.
And I plan on just dropping the pan, also know of any walkthroughs of dropping the pan and what to look for?
Thanks

This!
I went to GM to get fluid when I did my ss3600 and the tech told me GM switched it all to dex 6 so thats what I have in there.
There seems to be some confusion if its a synthetic mix though. It didnt say on the jugs. All I know is on the Yank card they sent with the verter says dex 6 is ok to use.
You can still get dex3 at auto stores though. I pretty sure non synthetic is recomended.
Theres a few pics on my install thread that might help a little.

Here's a comprehensive article on Dex VI, if anyone cares to read it:

There is technically no more "Dex III" labling, as GM no longer licenses this. What used to be labled as Dex III is now typically sold under the generic name "Dex/Merc".

Easiest way to know for sure is to make note of how much you take out. Should be aroung 5 qts but I'm not certain. Just do a best guess. It's better to be a little over than a little under.

I don't believe I've ever changed the filter seal on either of my current 4L60Es, and after several filter changes the stock seal is still fine.
