Mobil1 Synthetic LV ATF HP 1 Quart

Mobile 1 is good stuff. Can you find other brands just as good yes. But, I bought this due to recommendations that it stopped the slipping of certain GM transmissions. I did change it and it did help the jerkiness of my trucks transmission, although not entirely. I plan on doing it again in six months due to it takes about 2 to 3 drain and fills to get all the old original out. Will update review later.

To help with the 8l90 shudder

This was used for the 8L90 transmission in my 2015 Yukon XL Denali. It's recommended to take care of the shudder from the torque converter as well as the hard shifting.My best guess as to why it works is partly because it's a thinner fluid, so it takes less time to circulate through the transmission and do it's thing.My hard shifting issue is caused by a temp sensor in the transmission, however this is still a smart upgrade as it's higher quality transmission fluid.

This is the fluid GM uses to fix the GM 8 speed shudder issue.

Worked great

Nothing much to say, it's the fluid GM specs for the Sierra/Silverado 1500 w/ the 8-speed.

I have a 19 new body silverado with the 8l90 transmission. It has all the known symptoms slipping, hard shift 1st to 2nd and shuttering. Used this fluid and clear up most of the issues. Still feel a little slip and a little bit of a hard shift occasionally. Definitely worth changing with this mobile one blue label synthetic transmission fluid.

Blue label shown in picture. Black label received. Disappointed as the blue label is the lastest formula. Ordered a case of blue label and needed 2 more. The 2 separate were ordered from this item and both were black label. Not happy with mixed product.
