Is there any good info for the tranny fluid change? Searching I have found very terrible info and no pictures. I found a couple sparce videos on youtube and it appears there is a side plug for how much to fill tranny along with some process of heating up the tranny fluid.

Does anyone have any pictures for the tranny fluid drain plug? Is it the little bolt under the tranny directly facing the ground? I have black plastic plug on top of tranny and assume this is the fill plug?

I guess I will have to upload a video on youtube after I do this.

You have no dipstick, I believe, so you have to use the fill hole on the side. I would start by checking your current level first (because it’s possible it’s incorrect). You need the fluid at the proper temperature first : 85-95C (185-203F). The fluid expands as it heats up. Too hot, the fluid expands too much, and you’ll underfill. Too cold, the fluid expands too little, and you’ll overfill. Do you have a Scan Tool to read your transmission fluid temp, or is it displayed in the DIC on your Nox? If not, most people would just bring the engine temp up to the range and go with that, but that’s engine temp - not transmission fluid temp. Not sure how accurate that is.

The drain plug is a small-headed bolt on the bottom facing the ground. Looks to be near the center seam, about halfway down. Note the torque. Don’t overtighten! Your oil level plug is on the side. The fluid should be right at the lip of the oil level hole when it’s at proper temperature. If fluid pours out, it’s overfilled. I’d verify this first, then reinstall the level hole bolt, then drain out the bottom, then re-fill with whatever amount came out, using Dexron VI.

To assure that you are getting the "exactly" correct amount of fluid, it is also important to have the vehicle parked on a level surface. If there isn't enough room for you to get under the vehicle, it may require jacking up both the front and rear of the car.

Or measure the amount drained and fill back with same amount. Did this on a 6T30 a few months ago and just jacked up the front, loosened the drain bolt, lowered the car, reached under and removed the drain bolt, let it drain till it stopped dripping. reinstalled drain bolt.

Then, put one quart back at a time filling the then empty quart with previously drained oil. I had some spare empty quart oil containers as well. Then just filled with the same amount. Afterwards, started the engine, went through PRNDM a few times stopping for the recommended 3 seconds in each position. Let engine run a bit and took it for a drive. Checked trans fluid temps on scan gauge and then verified fluid level on trans side port.

Don't know if you looked it up yet. . but the new 8,9, and 10 speed GM transmissions will NOT be easy to changed the fluid on. There is no easy to use fill or drain bolts. And,some of these newer transmissions are developing a "shudder" under low load, steady speeeds. Seems the transmission torque converter clutch or TCC, doesn't like the fluid and needs a triple drain/fill from the dealer. The oil pan has to be removed each time!

No, I have the 6-speed. One of the reasons why I wanted the 6-speed was I didn't want to debug a new transmission for GM without the salary.

On my 2011 there is a dipstick. I'll try to get pictures tonight.

Its in the same location were you would fill the trans.

Yes. . I know you have the 6 speed. Was just stating this for those here who do not...0:)

Try these video. . same transmission fluid drain and fill procedure.

As far as the “measure what comes out and put that same amount back in” method:

I do the same thing, but you *really* should determine if your *current* level is correct *before* you do that because if you don’t your level may *never* be right!

How many transmission failures over the years were due (at least in part) to incorrect fluid levels? Had to be *some* of them...

True, but that is what the follow up warm up, drive, and check level port part of the procedure is for. Measure and refill is just the first part of getting near what should be the righr amount. Read the whole GM procedure or watch the entire videos. They pretty well cover what needs to be done.

Thanks for all the info. If I heat up the tranny and nothing comes out the side hole how do I know if it is at the proper level before I start doing anything?

I see a black cap looks like it is on top side of tranny so this must be my fill plug. I have not pulled that out so not sure if just a cap or actual dipstick.

I will video everything and upload to youtube.

If you looked at the youtube videos I posted you yes,, they show wha tis athe fill cap and drain plug. . .
Have you looked at the youtube videos already there? There dozens for these transmissions.

If you've got the fluid at the *right temperature*, and you open the level hole, and nothing comes out, then you ask yourself - "Can I see the fluid *right there* at the bottom edge of the hole, or is the fluid just barely dripping out?" If yes, then your level is correct. If no, then you're under-filled (by some unknown amount).

Now, with *my* 2011 V6 Equinox, I have a dipstick, so I can drain, re-fill, check the dipstick and add (if necessary) in 1/2 pint increments (that's what the rule-of-thumb is). But if the vehicle has no dipstick, I guess you have to pull the level hole plug *again* and add until the fluid just starts to come out the hole.

*Should be* being the operative phrase there. You just never know - unless you check it.

Perhaps you missed it has already been stated. . Post # 4 in this very thread I tell how to check and verify the level. But I guess * some folks * just like to jump in the middle of things and rip away. . .

Maybe with you I have to repeat everything previously stated and shown in a thread? ? ?

I never said you do not have to * check and verify proper levels *. You fill it first with what you take out. . then verify at the level port using the previously mentioned warm up and cycling though the gears. Then when checking the side level port , you are verifying whether you need to drain or ADD fluid.

- - *Plus* - - I posted not one, but TWO Youtube videos on the previous page which also indicate how to verify the proper level.

See below - - -

Or measure the amount drained and fill back with same amount. Did this on a 6T30 a few months ago and just jacked up the front, loosened the drain bolt, lowered the car, reached under and removed the drain bolt, let it drain till it stopped dripping. reinstalled drain bolt.

Then, put one quart back at a time filling the then empty quart with previously drained oil. I had some spare empty quart oil containers as well. Then just filled with the same amount.

Note ; ; I did not say to just leave it at drain and replace what you take out. . . but have it your way. ..

JayTee2014,

By just draining, re-filling, then checking "AFTERWARDS" *only*, you're assuming your baseline level is correct and it may not be.

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.

If you have to be OCD about it .. . but it does not matter. If say, the fluid level was low when you checked BEFORE changing. . then what? Are you going to add some new fluid before changing just to make sure you *might* then be at the right level? That's simply nuts.

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.

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.

Uh .. yes, we have seen this before.

Drain old 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.
