This is what made me pull the trigger. All GM transmissions use the same friction materials,seal materials, and engineering in general. This is from a 8 Speed service bulletin .I know and I want to use a better fluid, why can't GM or Mobil just say it and make my brain happy?
Maybe I wasn't clear. I fully understand that only 5.5 qt drained out, but what does it actually hold? If it holds 12 (I'm just making up a number here) but only 5 come out without being opened up or flushed, you don't have all of the old fluid out, so then your 5 of new just mixes with the 7 old. Then you do it a 2nd or 3rd time after mixing the fluids around driving and then you have some degree of confidence that "most" of the fluid is new. I'm pretty sure this is the case with the Gen 1 Traverse.Read AlisoBob's original write up where he explains it's 5.5 qts but he adds 6.0 and drains the .5 out once the tranny reaches operating temp. I don't have shuddering on my 19 Traverse with 20k+ miles but many in the thread have said once they changed the ATF it shifts sooo much better and have not had the shuddering since...
Allot of factors play into how much drains out. The big one is the positioning of the car. The drain plug looks to be about in the middle of the transaxle case. If your a car isn't exactly level, some fluid will pool in either the front or rear of the case. Same goes for the sight plug. Its on the left side of the case. If your car is leaning a little to the left, or to the right.. this will effect the final fluid level. The simplest way is to refill it with what ever volume come out. It will be somewhere around 5.5 quarts. If it's much less than that. the fluid level was low to begin with so you need so set the level using the method I described.Read AlisoBob's original write up where he explains it's 5.5 qts but he adds 6.0 and drains the .5 out once the tranny reaches operating temp.
How do you not mix fluids and not flush? I did find something on the amsoil site that said the capacity of 9T65 is 10 quarts. But I don't consider that "official" really, and have no idea what the cooler also holds since I do have that vehicle option. I just feel 5.5 quarts seems light, and if that's all you drained/re-filled, I'm pretty sure you mixed fluids. JMO. If it was like 80-90% of the total, I wouldn't worry about it. But we are talking half here. Sure if you are doing this at less than 10k intervals you are more than covered. I'm at 50k, and most won't subscribe to that frequent of service.I dont recommend flushing, any transmission.
Totally incorrect. The sump holds 6 quarts and the converter and cooler hold another 4 so its ten quarts total. When you service it once your new fluid to old fluid ratio is already 6/10, which last time I checked was more than 50%.I just think the average Joe should know reading this that if they follow that, they are really only touching about half of the fluid that is in there.
Dude...why the attitude. You actually said 5.5 quarts...exactly...so we'll call it 55%. And you never mentioned a single word about a second fluid dump. That was my point. Based on your post you are now changing 6 quarts...ehem 5.5...every 30k miles.Totally incorrect. The sump holds 6 quarts and the converter and cooler hold another 4 so its ten quarts total. When you service it once your new fluid to old fluid ratio is already 6/10, which last time I checked was more than 50%.
(Maybe you're doing that common core math sh!t?)
Then , on the second service you dump the sump and refill it. You have 6 quarts of 100% new fluid + 4 quarts that are 60% new fluid and 40% old fluid.
That's equals 8.5 new quarts, or a 85% replacement.
From that point on if you do periodic changes, you are keeping the new to old fluid ratio in check, and replenishing the additives.
This is not rocket science.
It measured out a 5.5 quarts exactly.
I plan to do this again at 5000 miles, then every 30k miles afterwords.
The 6 quarts of ATF and the gold plug was $60 and a hour of time.
Your reading comprehension needs to be checked.......And you never mentioned a single word about a second fluid dump.
If you are servicing a neglected trans, do the "Double Dump". Service the trans, drive around the block a few times, and service the trans again. This gets most of the crap fluid out of the cooler, T/C, and valve body. Once done, you're good to go.
