Just did a filter and fluid change on my 4l60e and I didn’t order enough. I used eurol. There isn’t any local stores that have this brand, but they have others brands. Is it okay to mix different brands as long as the oil specifications is the same?
They are both GM Dexron IIIG, semi synthetic. The local brand is called IQ-X oil, which come from the Dutch company Kroon-oil. Parts and oils for American cars isn’t that easy to get in Norway unfortunately.

If they are the same spec then you can mix. How low is the transmission? The 4L60E will not tolerate much more than 1-2qts. Internal damage will happen. Its transmission fluid, not oil. Oil goes in your engine and differentials.

Do you mean the fluid level? If so, it’s right at the bottom of the hot mark. I measured after the car had been running for 5-6min and I had also done some gear cycles, leaving it in each get for about 10 seconds.

In my Norwegian dialect we say use the world oil instead of fluid, my bad.

Man, don't worry about your vocabulary. Here, in daily usage, they're different; but in the dictionary, they're both oils and they're both fluids.

Based on these 2 posts, your command of English is excellent. LOL, better than a lot of ours is.

Theres a reason I honed in on the oil/fluid. The OP is from NORWAY and I dont want him getting the wrong liquid to pour into his tranny, engine, diff, Tcase, etc. I also dont want him inadvertently telling his fellow norwegians the wrong term and they ending up using the wrong oil/fluid.

You are of course welcome to keep it in backwoods terms. ;)

I knew I should've added this...

I agree that it's better to know the correct word. I did not want him feeling bad about his word choice.

And it seems to me like they're doing fine, in Norway, with the way they express it.

@homesick @rockola1971 I understand why the correct word is important and also why you corrected me. I took no offense of this as I don’t have any blue hair nor do I wear any rainbow clothes. Autocorrect is also a good thing to have.

Now let’s end the “spelling competition”. If you have any knowledge on my original question it will be much appreciated.

At the bottom of the mark for level you are right at the problem area. I hope you didnt go driving around like that. You are over 1qt low.

It would be good to know what year, make, model, and engine you have, although for fluid checks it probably doesn't matter as long as this is posted in the correct year section.

The fluid is likely not hot enough for a proper check after running only a few minutes. Check your owner's manual for the proper warmup and temperature. The instructions for my '04 start with the graphic below, with more details after. I can tell you that I would struggle to get mine much over 160° F but once it won't go higher I figure that it's warmed up enough.

@rockola1971 No I haven’t been driving it. But from reading @Fless comment it seems that maybe my fluid isn’t hot enough. I have a Tahoe 5.3L 2001. Manual says the same thing. I kept the car idling for probably 20mins yesterday, and I did several cycles between the gears.

My mistake was I didn’t measure the amount of fluid I took out. Lesson learned
