ACDelco GM Original Equipment 10-9244 (88865618) Dexron VI Full Synthetic Automatic Transmission Fluid - 1 gal

I ordered this for my 2015 GMC Sierra 4WD SLT with the 6L80E transmission. Since there are two different best seller listings with different part numbers I used AcDelco’s website to verify the correct fluid. This fluid (88865618) was first used in 2021 and is full synthetic, even though the spec sheet in the listing says no. The spec sheet in the ad is for the discontinued mix (other best seller) that is a synthetic blend. The bottle is identical to AcDelco website.I bought a total of three gallons to fully change out fluid. The price is great. Will definitely be ordering again for the next service when it’s due. Fast secure shipping. Each bottle had lid tape to prevent spills . Thanks!

I put this in my 2019 Buick Enclave.The shifting is very much improved.

Very pricey:

Happy with product 👍

Great synthetic fluid for my cadillac.I trust brand name, I did a empty and refill on the transmission after 100k , about 2 months ago, still shifts smooth and as expected, will do a another empty refill in about 20k miles again to keep fresh fluid in transmission as preventive maint

Service good

Quality fluid

I used this to change my transmission fluid in my 2016 Silverado 2500. I used a fluid pump to suck most of the fluid out of the pan through the dipstick. I then dropped the pan and changed the filter. Buttoned it back up and filled her back up to full when she got warm. I then ran her for about a thousand miles and used the pump to pull out another five quarts and refilled. I'm doing this process about every 40k. So many issues out there with these transmissions and I tow a lot so I'm trying do what I can to prevent the implosion. I like to use the oem stuff so I don't have to worry about it.
