A very elderly family member failed to get TSB(SB-10056459-3388) done on a 34k mile Acadia within the 10 year limit, that switches fluid to Dextron VI. Surprisingly the power steering still works but the fluid is really black. What fluid would you use to flush it out with for now, to buy some time. What is the OEM fluid? Signed by: GM Vehicle Dumb

Added: Confirmed the original OE fluid as GM part #89021184 . Now searching for alternatives.

Gm is one of the lines we carry. Dex VI is what we would use.

Yes, but this vehicle was not converted. Read somewhere not to use new fluid unless.

Well I'm sure everyone is dying to know the final dillio on the GM power steering fluid dilemma. Be glad we own Hondas. After I cross referenced a replacement part # for the original #, I managed to find this fluid locally with a different #. I was able to come to the conclusion that it's the same stuff, by reading a Bob the Oil guy thread. It's just a larger bottle. They dont tell you these things. You got to painfully figure it out the hard way.

Dex 6 is speced after rack replacement, due to the seals not being compatible with the original fluid. Either dex 6 or the original will work fine as long as you know the rack hasn't been replaced with a rack containing the new composition seals.

I know the TSB was never performed..., so no new seals.
If it were my vehicle, I'd have put Full Synthetic Valvoline MaxLife ATF. Hence the pain of finding OEM.

Both Lubegard and Amsoil claim that their synthetic power steering fluid can be used where GM 89021184 was specified.
COMPLETE Synthetic Power Steering Fluid - Lubegard
Multi-Vehicle Synthetic Power Steering Fluid PSF - AMSOIL

🤔 If this AutoZone Honda Power Steering Fluid has the GM # 89021184 specification, does that mean my OE Honda PS fluid will work in this GMC power steering system?

There, I made a reason to post this GMC problem in a Honda forum. Lol

You're just lucky there's someone here who will find it in his heart to forgive not just seven times but seventy-seven times.

He beat me to it!

Many on the Traverse forum didn't know or never got it done on their early 1st gens. If you are running the original rack you must use the original power steering fluid. If that rack fails the only racks available will use DexVI so the switch should be made at that time.

My Traverse at 100k had some really dirty PS fluid, it took me 5 suck and fills before the fluid was a color I liked.

I read that you could use Dex VI in the old ps system, so long as you completely vacate the old fluid from the system. Mixing the 2 fluids can cause seals to swell. Since it's not my vehicle I've been looking for alternatives. So far I have put in 64 oz of OE Fluid and it did not clear. I got another 32oz on the way for this afternoon.
I was just curious about using Honda fluid since I found a correlation.

Well with 3 fresh quarts ($37) of OEM ps fluid pushed through the system, with the wheels off the ground, going lock to lock on the steering wheel, I'm somewhat satisfied, even though the fluid is not sparkling clean. I think I'm going to stop there.
Now, what to do with this 10 year old Dex Cool puke in the radiator. 🤦‍♂️

Replacing with Honda PSF is a move in the right direction. Just need to replace everything else. 🤣

Go to AutoZone.
Look for AutoZone branded Honda Power Steering Fluid 12oz. (Part # AZ860211 SKU # 84948) It's $5.29 a bottle. In the notes it has the old GM # specd for this 2010 GMC. Their photo is terrible.

After all the research, im pretty confident in saying that you could use AC Delco Power Steering Fluid item # 19329448 (32oz) or 19329450 (16oz) in our Honda's.

Same thing happens even for just "autozone.com".
The site loads normally and, after a few seconds, the "oops" message appears.
Haven't encountered that issue with any other websites.
This started happening a few months ago.
