Have you looked at the youtube videos already there? There dozens for these transmissions.
I just watched both videos and these do look great. I will probably upload my own youtube video of the process so equinox and terrain people can have their own video.

Thanks to the posters.

Glad you found the videos useful. The 6T70 is one in the 6Txx family of GM transmissions that have been used in various GM vehicles. So much of the architecture is the same or similar like the drain and fill ports. Size, internal parts, and capability of course are different. Even the small 6T30 is an interesting little marvel.

Pretty stout transmissions and many have found if you simply drain/fill every 30K to 40K miles (depending on which size) they are dependable. I've changed fluid on a couple that went 70,000 to 90,000 miles before an fluid change and the fluid is pretty nasty black by then.

JayTee2014 Yeah. .. this all just so hilarious. - -

Maybe also make sure tire pressure is correct so that the it can be assured that the vehicle is at the proper level as well. etc . . etc. . . yada yada
And the planets are in the proper alignment.

RIT333 Well, while we are nit-picking, I'm not sure if it was mentioned, but when doing a fluid change, make sure that you know where you are going to be adding the fluid, and practice taking off the fill closure before draining the fluid. Otherwise you be really screwed trying to transport a car to the dealer with a empty transmission, or at least low by how much you have drained out.

JayTee2014 Uh .. yes, we have seen this before. Totally unnecessary when references and videos are posted.

Drain old fluid. . . fill with new fluid. .. check level as per procedure. . . check fluid level again as per temps of fluid, shift through gears, take a drive. .. check fluid level again. Done.

I guess we're going off the rails again. We've seen this before.

You're primarily checking for an over-fill condition. If you're under-filled, well, that's mostly just informational - unless you don't do the AFTER check (for whatever reason).

As I said, it's a 'fine point'.

Next time, use a bigger font.

I'm just making the distinction that it's a good idea to *also include* a check BEFORE doing the drain and re-fill because you could be over OR under-filled to begin with.

And then you're driving it at least one more time that way. More if you don't do the AFTER check (for whatever reason).

It's a fine point, but one worth making, I think.

Ridiculous.. . All that matters is that after you drain and fill. . . then check the level.

Again. . have it YOUR way. . . Better check with rbarrios then, because he has been doing it "wrong" according to you in two GM vehicles for 10s of thousands of miles.

Follow the GM procedure. . . check for proper level - - AFTER - -- drain and fill.
