Transmission Fluid Change

You shouldn't have to use any kind of sealant on the pan mating surfaces or gasket. Also, if yours has the rigid gasket, reuse it. They are designed to be able to be reused. Lastly, that filter you have is the wrong one. The shallow pan filters are metal, and the deep pan filters are all plastic. Look at the difference in overall height side by side. You'll see the top of the pickup tubes will differ by about a half inch. If you use that metal one, the trans will starve of fluid during driving. Also, the seal will be just fine. Some are partially rubber coated, others a completely coated. It'll be just fine.

 

Could you take a picture of the little bits of seal left in the pump body? It sounds like it won't be an issue, but it would be easier to discern with pics.

Thanks for the response. This is exactly what I thought as well, because the actual filter part like I mentioned is much more 'low profile' than the original. I am going to take it back tomorrow and hope they have the right kit. I will try to get some light up in the hole and take a picture tomorrow. 

 

Secondly, I thought the same thing about applying sealer to the gasket. However, everyone I have talked to said it should definitely be done, so far you are the only that has agreed with me. I am afraid that the sealant could act like a glue and adhere too early which could cause part of the gasket to crimp then actually cause a leak.

The reason you see RTV goobered all over everything on peoples rigs is because of the smart people that over torque the pan bolts while using the aftermarket cork or rubber gaskets (after they tossed the factory one). This then distorts the pan flange and causes leaks with any gasket. The factory rigid gasket has metal washers embedded in the bolt hole areas that prevent over-torquing.

Grumpy Bear and carkhz316,

 

Thanks for the responses. I am one of those guys that over torques everything unfortunately. My father has a torque wrench I can probably borrow. Does anyone know what torque my bolts are suppose to be torqued to? Also where do you locate such information?

So my father says he still thinks that metal ring is in there. It sort of looks like there still could be something from the pictures. The seal that came out was pretty much complete but it was all rubber unlike the new one. You guys still think something is up in there?

So the whole metal portion of the seal is still there. The seals on these are rubber coated rings of steel. You have 2 options for getting that ring out now (you have to since you peeled the rubber off of it.). First, a sharp chisel to nick the edge and fold it in on itself and then grab it with a needle nose pliers and pull it out. The second method (which I am a fan of) is to get a 1/2 or 3/4 (I can't remember.....take the new seal and match a plug to that) NPT (pipe thread) plug from your hardware store/ parts store and thread it in as you would a bolt to the point of nearly bottoming out. Then grab the end of the plug and rock/ wiggle it back and forth and it should pull right out. Hopefully this works for you.

Yes/ Metal part of the seal is still there. Do as described above or as Nick showed.

 

It's 1/2" NPT that will work

If you look at the thread I posted. I just used a small screwdriver to collapse the seal inward, then I was able to pull it out with the pliers.  It isn't very hard and will bend in easy.  Just take your time.

Thanks for all the replies gentleman, as always it is much appreciated. I already took a screwdriver and tried to gently tap it inward with a hammer. I had no luck in doing so. I might give it another go but I do like the pipe threader idea for sure. So I went to Advanced Auto and they did not have the ACDelco one in. So I went over to AutoZone, nice people but did not know what I was talking about. He brought out the same thin filter with the metal bottom and told him that was not it. Then he came back with this one. The little sticker on the cardboard says ACDelco on it and it definitely looks identical to the one I took out.

So for better or worse I got sick of dealing with the seal and I took a pick with a dull end and just drove it up in there. I bent the seal and tore it out with a pair of pliers. However, you can see where I put an indent into where the hole starts over to the right side of this picture. I got the new seal on and it looks good. I think worst case scenario some fluid will leak through and evade the new filter. However, no metal shavings of anything are likely to get through. Also the actual part of the seal that does work is around the top and it looks like that is pretty good still so I think I am good to go.

I know a lot of you guys probably frown upon 'snake oil' type products. I have heard a great many people swear by this stuff and assert how useful it is. When I was putting stuff into my cart on Amazon I must have accidentally clicked this twice because two of them arrived. It says to add two for larger harder working transmissions. I realize this probably does not describe mine, maybe if I had an Allison transmission on a Duramax or something. Having this in mind, you guys think it could help or hurt to add two of these to my transmission instead of one, or generally what you guys think of adding it in the first place?

I wouldn't use it.  Just use a dexron VI fluid and you will be good to go.

Agreed. I would leave it off since you will have fresh fill of synthetic fluid.

Good job on removing seal. See it wasn't that bad......

 

Did you ever mention if you had any large amount of material in the pan upon removal? Did you take a shot of it?

    • Still looks like a rivet to me in the pics, I don't see a nut and none of the pics show the head of the screw. But if you says so.....
    • Thanks for all the help so far!   I did try right from 2026 right down to 2021, and only from 2023 down lets me select the option for tire psi change, but I get the vehicle not supported error!   I'll definitely try it under Chevrolet after work today, and I'll get the sensor number from gm for my truck tire sensors. And I'll let you know if it works for me under Chevrolet!   And if that doesn't work, I'm going to guess that what @Atlas said about maybe I have a different body control module could be true!  
    • From where I'm sitting this sounds like a compatibility problem. I'm assuming the 2007 was a 900-series truck, and not an 800-series (they were sold side-by-side in dealerships that model year), since it starts and runs.   This is why I HATE post-2006 vehicles. Everything becomes a huge problem when you try to keep the thing running for longer than the manufacturer has designed it to.    I can't remember when Global-A architecture started - either '10 or '11. For your sake, you had better hope it's '11, or you're going to be spending some BIG money to correct this cluster-eff. That's something you need to find out before doing anything else. You may have several computers bricked ... but the fact that it runs tells me you MIGHT be ok here.     EDIT: Just did a quick refresher. You're screwed. This is Global-A. The 2 systems are NOT compatible in the slightest. Once you get the correct engine in there that IS compatible, you're going to need to see how many computers are locked. Absolute NIGHTMARE to straighten out, too. Your buddy might be better off cutting his losses and finding something else.   Welcome to post-2006 vehicle electronics. This is why I quit the industry, and drive nothing built after 1994. This stuff takes all the fun out of wrenching!

    • True, hard to say what differences there may or may not be between Chev and GM as well as a production year or mid year part change either.    I just found it odd that under the Sierra choice on the Autel that many of the last few years of production year did not include the choice of changing the tire pressure but if that is an Autel thing or a GM thing as to why the choices were not there. Knowing what tpms sensors are on the truck should give some guidance into which choices on the tool even make sense to try as I wouldn't give up just yet with the tool but I guess he will see what if anything he comes up with if he finds out a bit more info and tries a few more things on the Autel.
